Part Number: OPA454
Tool/software: TINA-TI or Spice Models
Hello, i am comparatively new to this analog part of the world and usualy deal with power supplies' designing for the embedded products. I have been working on generation of an oscillator. It needs to drive a capacitive load of around 20mA with 50Hz, 48Vpp ac signal. I just made a TINA simulation for the same using OPA743 as oscillator and then amplifying its output with OPA454. I got the waveform i needed.
Out of curiosity, i tried to use OPA454 Directly to get a 48Vpp ac, but the output was even lower than opa743. Any inputs on this?
