Test Circuits

The circuits used for most DC and AC tests are shown in

Figure 1-4 and Figure 1-5. Lay the bypass capacitors out

as discussed in

Section 4.3.10 “Supply Bypassing

and Filtering”. RN is equal to the parallel combination of

RF and RG to minimize bias current effects.

Most Inverting Gain Conditions.

The circuit in Figure 1-6 tests the input’s dynamic

behavior (i.e., tSTR, tSTL and tODR). The potentiometer

balances the resistor network (VOUT should equal VREF

at DC). The op amp’s Common-Mode Input Voltage is

VCM = VIN/3. The error at the input (VERR) appears at

VOUT with a noise gain of approximately 10 V/V.
