is determined by C3, C4, and the input transconductance, increases with gain, thereby, optimizing frequency
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 us the I × R drops “inside the loop” and virtually eliminating this
error source.
Typically, IC instrumentation amplifiers are rated for a full ±10
volt output swing into 2 kΩ. In some applications, however, the
need exists to drive more current into heavier loads. Figure 29
shows how a high-current booster may be connected “inside the
loop” of an instrumentation amplifier. By using an external
