6.1 Application Information

The INA146 is a programmable gain difference amplifier consisting of a gain of 0.1 difference amplifier and a programmable-gain output buffer stage. Basic circuit connections are shown in Figure 6-1. Power supply bypass capacitors must be connected close to pins 4 and 7, as shown. The amplifier is programmable in the range of G = 0.1 to G = 50 with two external resistors.

The output of A1 is connected to the noninverting input of A2 through a 10-kΩ resistor which is trimmed to ±1% absolute accuracy. The A2 input is available for applications such as a filter or a precision current source. See application figures for examples.
