9.2 Typical Application

Wide gain bandwidth, low input bias current, low input voltage, and current noise make the OPAx354 family of devices an ideal wideband photodiode transimpedance amplifier. Low-voltage noise is important because photodiode capacitance causes the effective noise gain of the circuit to increase at high frequency. The key elements to a transimpedance design, as shown in Figure 37, are the expected diode capacitance, (which include the parasitic input common-mode and differential-mode input capacitance) the desired transimpedance gain, and the gain-bandwidth (GBW) for the OPAx354 family of devices (20 MHz). With these three variables set, the feedback capacitor value is set to control the frequency response. Feedback capacitance includes the stray capacitance , which is 0.2 pF for a typical surface-mount resistor.
