Table 5-1 Pin Functions

PIN		TYPE	DESCRIPTION
NAME	NO.	TYPE	DESCRIPTION
A0	4	Input	Gain option pin 0
A1	5	Input	Gain option pin 1
A2	1	Input	Gain option pin 2
DA_IN+	9	Input	Connection to output difference amplifier summing node
DA_IN–	12	Input	Connection to output difference amplifier summing node
DGND	16	Power	Ground reference for digital-logic and gain-setting pins
IN–	3	Input	Negative (inverting) input
IN+	2	Input	Positive (noninverting) input
LVDD	7	Power	Output-driver positive supply
LVSS	14	Power	Output-driver negative supply
NC	8	—	Do not connect
NC	13	—	Do not connect
OUT	11	Output	Output
REF	10	Input	Reference input. This pin must be driven by a low-impedance source
VS+	6	Power	Input-stage positive supply
VS–	15	Power	Input-stage negative supply
Thermal Pad	Thermal pad	—	The thermal pad must be soldered to the printed-circuit board (PCB). Connect thermal pad to a plane or large copper pour that is either floating or electrically connected to VS–, even for applications that have low power dissipation.
