Part Number: INA260
Hello, I am planning on using the INA260AIPWR PWR/Current Monitor in my next design. I want to know that max current the device can handle through pins IN+ to IN- would that be the "Maximum Continuous Current" found on page 6 under the Integrated Shunt heading? That spec is +15A and -15A. I need to be able to handle 40A could you suggest a device if this one can't handle that current?
Thanks,
Joe
Part Number: INA226-Q1
Hi,
Our condition is in a high current sensing application, per considering the shunt resistor power dissipation, we may consider to use shunt resistors parallel for INA226-Q1 current sensing.
However, there should be more we need to take care of the layout or placement, is there TI's reference design for INA226-Q1 with using parallel shunt resistors for current sensing that could be for reference.
Or how should we do in this kind of application? Currently we may use 4 pcs shunt resistors parallel, and its output have 4 pcs MOSFET parallel with using LM5060.
I'd appreciate for your help.
Thanks much,
Lewis

Dear TI Experts,
Could you kinldy provide the input capacitance of VIN+1/VIN-1；VIN+2/VIN-2；VIN+3/VIN-3 Pins? We can find it from datasheet, thanks.
Part Number: TLV3201
Hi team,
May I know if TLV3201 is exact function with TS3011(SC70-5 package)?
Or could you recommend which part is fully same function with TS3011 and propagation delay is similar with TS3011 as well?

Part Number: TMS320F28075
Hi
We are using "TMS320F28075" micro controller in our design. Currently flash is accessed and programmed using JTAG interface via micro controller ie.PC--->JTAG interace-->Micro controller--->Flash memory
We would like to know if it is possible to use USB interface to program the bootloader to the flash via micro controller i.e PC--->USB interface--->Micro controller--->Flash.
Kindly let us know how can we implement this using "TMS320F28075".The flash memory we are using is SPI Flash "M25P40-VMN6TPB".
Part Number: OPA2188
Hi Support team
my customer adopted OPA2188 for output current measurement, the application circuit is as following
the current shunt resistor is 5mohm // 5mohm = 2.5mohm
they observed that the current reporting is NOT smoothly in heavy current condition
may i have your help to take a look and kindly advice how to make it smoothly

Part Number: AMC1100
Hi
I need the FIT rate of AMC1100DUBR.
Part Number: LM7171
Dear Tech Support
I am interested in using the LM7171 designed as a high frequency astable multivibrator, similar to the illustration shown in the data sheet. My question is: there are
no known values attributed to the diodes and zener diodes mounted across the output? Are these set to limit the output swing or, are they there to keep the signal on
the output locked to the zero baseline? How are the values of these diodes determined? Lastly, it seems that the output is a triangle wave at half supply level? Will I
need a second op amp such as, an LM7171 to function as a high frequency amplifier and a wave conversion to a square output with 50% duty cycle?
Regards

I am currently playing organ in a loud 70s rock/metal band. I am playing through a 100watt ampeg solid state bass head into a cab with 2 15' speakers in it. The problem is it's just not cutting the sonic mustard. The guitarist is playing through a 100watt Mesa tube head half stack. Even at practice when the guitar amp is on five I struggle to cut through. Does anyone have any solutions without spending thousands of dollars?
Part Number: THS6212
Dear Sir or Madame
We want to use THS6212 to current control a string of LEDS, we understand that the THS6212 is aimed for a total different application area but we hope it can be used for our application.
The reason the THS6212 is chosen is it is cheap, can drive at least 1 ampere with a slew rate of 3800V/usat 150MHz bandwidth
Our idea is to let the THS6212 drive a string of LED’s to ground via a 0.1 ohm shunt resistor to ground and then feedback the voltage over the shunt to the - input.
In this way we can vary the current through the LED's as we wish by applying a chosen voltage to the + input.
The basic requirements for our application is to control the LEDS in two ways
Is it possible to drive the THS6212 on 24V (the datasheet says +-12 Volt)?
Is there any other suggestion to archive this LED control (the op amp gives such elegant and simple solution)?
Is there a dedicated LED driver chip that can archive this (which we obvious is not aware of)?
A second solution we been thinking of is a much simpler op feeding a Darlington that drives the LED’s, perhaps it is better?

Part Number: AMC1302
Hello,
My customer has been using AMC1302 for current sensing. They have found AMC1302 output distortion when input is 20KHz, +/-40mV voltage signal. The gain of AMC1302 is 41. However, with the same schematic and parameter, the input signal decrease to 550Hz, we no longer see the distortion.
Could you explain what possibly cause the distortion?
This the schematic:
This is the input& output waveform:
Thanks!

Hi，
I have some problems with using THS4531.
We knowTHS4531 is a differential op-amp that allows single-ended inputs
And the single-ended input voltages is 0-5V, how can I get the differential signals with 0-3V?
I have tried some methods, but it did not work.
I tried to reduce the 0-5V voltage to 0-3V input to the THS4531, and the output waveform is shown in the figure.
Looking forward to your help.
Part Number: INA226
I have a client looking for something similar to the INA226 features ( I2C capable/16bit resolution ) but I needed more features listed below:
Or can you recommend something similar to LTC1859 ( but I need high impedance Mux input ) with the following features
Thank you for helping me.
Part Number: LMH6321
Hi,
We're designing a unity gain buffer amplifier for a 38 kHz, 0 - 3V or 0 - 5V PWM signal. The specs aren't particularly fussy; the rise and fall times with a slew rate of 10 V/us would probably be fine so this part is more than adequate there. We do need a higher output current which is why this part looks good. It's to provide the TTL input to a laser diode module, other than mentioned signal quality/integrity doesn't need to be considered.
Again the desired output signal should go from GND to +3V or GND to +5V, therefore will it be ok if we connect the V- input of the LMH6321 to GND? We don't have a negative supply and don't need it. So for our application we'd need to connect both the GND and V- pins to the overall GND net. Will that work for this part?
We want to keep the design as minimal as possible in general, so we'd also like to leave the EF and CL pins either floating or tied to GND or V+. Will that be ok? I didn't see much detail on those pins in the datasheet.
If our intended implementation won't work for this part, can you recommend another part (either a buffer amp IC or even just an op-amp designed for unity gain applications) that have slew rate > 10 V/us and output current > 200 mA?
Thanks very much,
Matt
Part Number: AMC1302-Q1
The AMC1302-Q1 datasheet EC table shows CMTI specs of 55 kV/us min and 80 kV/us typ, which do not match the CMTI values listed on the front page (70 kV/us min, 140 kV/us typ) and parametric spec on TI.com. Which are the correct CMTI min specs?
Also, do we have an auto-qualified reinforced isolated current sense amplifier or modulator IC with Min. CMTI > 75 kV/us for inline phase current measurement on a 3-phase output? This is needed for a traction inverter application with SiC switching. Any device existing or on the roadmap?
Thanks,
Alan Ocampo
