FIGURE 2. Offset Adjustment.
FIGURE 3. Precision Difference Amplifier.
For low source impedance applications, an input stage using OPA27 op
amps will give the best low noise, offset, and temperature drift performance.
At source impedances above about 10k
, the bias current noise of the
OPA27 reacting with the input impedance begins to dominate the noise
performance. For these applications, using the OPA111 or dual OPA2111
FET input op amp will provide lower noise performance. For lower cost use
the OPA121 plastic. To construct an electrometer use the OPA128.
