Other Parts Discussed in Thread: OPA350, REF2030, , REF2033, REF2025, TIDA-00316
Hello, TI experts.
I'm designing a transimpedance sensor using MEMS capacitor.
I configured a circuit using TI's OPA1S2385, REF2030, and OPA350.
The circuit consists of transimpedance amplifier, all-pass filter, SAC ADC, voltage reference and added buffer.
Here is my schematic.
Here are my questions:
1. Without OPA350 buffer, can REF2030 drive OPA1S2385 and ADC?
2. If I connect the OPA1S2385 supply voltage pin to 3.3 V from LDO instead of BUFF OUT, is there any degradation of performance?
Best regards,
