6.1 Application Information

Figure 6-1 shows the basic connections required for operation of the INA114. Applications with noisy or high-impedance power supplies can require decoupling capacitors close to the device pins as shown.

INA114 Basic Connections. Figure 6-1 Basic Connections.

The output is referred to the output reference (Ref) pin, which is normally grounded. This connection must be low-impedance to provide good common-mode rejection. A resistance of 5Ω in series with the Ref pin causes a typical device to degrade to approximately 80dB CMR (G = 1).
