8.2.1.2 Detailed Design Procedure

To achieve a maximally-flat, second-order Butterworth frequency response, the feedback pole must be set to:

Equation 1. OPA356-Q1 q_fback_slos884.gif

Use Equation 2 to calculate the bandwidth.

Equation 2. OPA356-Q1 q_bw_slos884.gif

For other transimpedance bandwidths, consider the high-speed CMOS OPA380 (90-MHz GBW), OPA354
(100-MHz GBW), OPA300 (180-MHz GBW), OPA355 (200-MHz GBW), or OPA656 and OPA657 (400-MHz GBW).

For single-supply applications, the +INx input can be biased with a positive DC voltage to allow the output to reach true zero when the photodiode is not exposed to any light, and respond without the added delay that results from coming out of the negative rail; this configuration is shown in Figure 30. This bias voltage appears across the photodiode, providing a reverse bias for faster operation.
