OPA314 is a good choice. I prefer TLV6741; reducing noise was a key factor in its design. R243 and C217 are set to 73kHz, if you need less bandwidth then C217 can be increased to reduce total noise level.
Hi V Pot,
You might want to consider OPA320 or TLV6741.
The exact meaning of low noise is going to depend on your circuit configuration. A bipolar input op amp with very low voltage noise may have significant current noise, which will dominate the noise…
Other Parts Discussed in Thread: OPA172 , TLV9062 , TLV6741 , OPA377 Hello,
I have enjoyed reading tidu765. I am working on a design to try to detect a 50-100 hz signal based on this design reference.
Has anyone modified tidu765 to run on a 3.3v supply? Is this…

Part Number: TLV2772 Other Parts Discussed in Thread: TLV2771 , TLV6741 Hello,
I am looking for an appropriate charge amplifier for a Piezo sensor.
The sensor is a PVDF foil, metallized with gold with a size of ~5x5mm2.
The thickness is 28µm (also available…
