response. T The diodes to the supplies are only necessary if input voltages
outside of the range of the supplies are encountered. In higher
gain applications where differential voltages are small, back-toback Zener diodes and smaller resistors, as shown in Figure
26b Any resistors in series with the inputs of the AD625 will degradethe noise performance. For this reason the circuit in Figure 26bshould be used if the gains are all greater than 5. For gains lessthan 5, either the circuit in Figure 26a or in Figure 26c can beused. The two 1.4 kΩ resistors in Figure 26a will degrade thenoise performance to:
RESISTOR PROGRAMMABLE GAIN AMPLIFIER
In the resistor-programmed mode (Figure 27), only three external resistors are needed to select any gain from 1 to 10,000.
Depending on the application, discrete components or a
pretrimmed network can be used. The gain accuracy and gain
TC are primarily determined by the external resistors since the
AD625C contributes less than 0.02% to gain error and under

As previously stated each RF provides feedback to the input
stage and sets the unity gain transconductance. These feedback
resistors are provided by the user. The AD625 is tested and
