Test Circuits

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

Figure 1-5 and Figure 1-6. Lay the bypass capacitors

out as discussed in Section 4.3.10, Supply Bypass-

ing and Filtering. RN is equal to the parallel combina-

tion of RF and RG to minimize bias current effects.

The circuit in Figure 1-7 tests the op amp input’s

dynamic behavior (i.e., IMD, 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/2. The error at the

input (VERR) appears at VOUT with a noise gain of

10 V/V.
