Part Number:OPA348-Q1
Hello team,
My customer have a question. please review below question and let me know your opinion.
1. Bypass capacitor : Which value is correct? 0.1uF or 0.01uF?
- Datasheet section 7.3.1(12 page) Power supply pins should be bypassed with 0.01uF ceramic capacitors.
- Datasheet section 8.1 (16page) Power supply pins should be bypassed with 0.01uF ceramic capacitors.
- Datasheet section 9. (19page) Place 0.1uF bypass capacitors close to the power supply pins to reduce errors coupling in form noisy or high impedance power supplies.
- Datasheet section 10.1(20page) Connect low ESR, 0.1uF ceramic bypass capacitors between each supply pin and ground.
2. GBW
- Datasheet 7page, GBW is 1MHz at Cload = 100pF, Temp =25C.
- GBW is fixed value regardless of Cload and temp? If not, Would you let me know variation of GBW value per Cload and Temp?
Thank you.
