PINTYPE(1)DESCRIPTION
NAMENO.
IN–2IInstrumentation amplifier negative (inverting) input
IN+3IInstrumentation amplifier positive (non-inverting) input
OUT6OInstrumentation amplifier output
A_IN+5IReference amplifier positive (non-inverting) input. This pin usually connects to a reference voltage externally.
A_OUT1OReference amplifier output. This is connected internally to the 60 kΩ resistor of the INA which is also called as REF node.
A_IN–8IReference amplifier negative (inverting) input.
V–4—Negative supply
V+7—Positive supply
(1) I = input, O = output
