PHOTODIODE APPLICATION
The AD854x family has very high impedance with an input bias
current typically around 4 pA. This characteristic allows the
AD854x op amps to be used in photodiode applications and
other applications that require high input impedance. Note that
the AD854x has significant voltage offset that can be removed
by capacitive coupling or software calibration.
Figure 40 illustrates a photodiode or current measurement
application. The feedback resistor is limited to 10 MΩ to avoid
excessive output offset. In addition, a resistor is not needed on
the noninverting input to cancel bias current offset because the
bias current-related output offset is not significant when compared
to the voltage offset contribution. For best performance, follow the
standard high impedance layout techniques, which include the
following:
Shielding the circuit.
Cleaning the circuit board.
Putting a trace connected to the noninverting input around
the inverting input.
Using separate analog and digital power supplies.
