Figure 7-1 shows the basic connections required for operation of the INA141. Applications with noisy or high impedance power supplies can require decoupling capacitors close to the device pins as shown.

Figure 7-1 Basic Connections.

The output is referred to the output reference (Ref) pin, which is normally grounded. This connection must be low-impedance to maintain good common-mode rejection. A resistance of 8 Ω in series with the Ref pin causes a typical device to degrade to approximately 80 dB CMR (G = 10 V/V).
