Pin Functions

PIN I/O DESCRIPTION
NO. NAME
REF 5 I Reference input. This pin must be driven by low impedance or connected to ground.
RG 1, 8 — Gain setting pin. For gains greater than 1, place a gain resistor between pin 1 and pin 8.
V– 4 — Negative supply
V+ 7 — Positive supply
VIN– 2 I Negative input
VIN+ 3 I Positive input
VOUT 6 O Output
