SNAS781E October 2020 – July 2022 REF70
For this design example, use the reference op amp recommendation listed in Table 10-2 for the buffer circuit.
|SELECTION PARAMETERS||OP AMPS|
|Low voltage and current noise||OPA211, OPA827, OPA828|
|Low offset and drift||OPA189|
The REF70 turn-on time is dependent on the output capacitor. In certain applications that require a fast turn-on can require a smaller output capacitor as shown in Figure 10-4
