OPA2387: OPAMP section for design review

Part Number: OPA2387
Other Parts Discussed in Thread: OPA387

Hello TI team,

I have designed buffer circuit with OPA2387DSGR. Inputs arte pressure sensor (0-5V output) and thermistor. Buffer output is connected to ADC ADS114S08IPBSR (please refer follwoing link for more information) https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/1651315/ads114s08-schematic-review-of-ads114s08ipbsr-and-opa2387dsgr?tisearch=e2e-sitesearch&keymatch=%20user%3A617902#

I have attached the schematic images and pressure sensor data. Please review the design and let me know the changes if any required.

The image of your schematic has illegible component values. Assuming the circuits are biased within OPA2387 linear input/output range with high output impedance (no large capacitive load), I do not see any issues.
