126.96.36.199 Operational Amplifier Considerations
The operational amplifier used for this design example requires the following features:
- Unipolar supply operation (5 V)
- Low input offset voltage (< 10 µV) and input offset voltage drift (< 0.5 µV/°C)
- Rail-to-rail input and output capability
- Low thermal and flicker noise
- High common-mode rejection (> 100 dB)
OPA333-Q1 offers all these benefits and is selected for this application.
