SBOS690A July 2016 – December 2019 OPA2626
The circuit shown in Figure 56 measures the ac parameters of the OPA2626. Configure V+, V–, and CLOAD as desired. The THS4271 family is used to buffer the input and output of the OPA2626 to prevent loading by the gain phase analyzer. Monitor the input and output voltages on a gain phase analyzer. Use this circuit to measure the gain bandwidth product, and open-loop gain versus frequency versus capacitive load.
