Pin Functions

PIN DESCRIPTION
NAME NO.
VOUT 1 Single-Ended Output Voltage
V- 2 Negative Supply Voltage. This pin should be connected to ground.
+IN 3 Positive Input
-IN 4 Negative Input
RG 5 External Gain Resistor. An external capacitance (CG) may be added in parallel with RG to limit the bandwidth.
