Table 6-1 Pin Functions

PIN		TYPE⁽¹⁾	DESCRIPTION
NAME	NO.	TYPE⁽¹⁾	DESCRIPTION
IN–	2	I	Negative (inverting) input
IN+	3	O	Positive (non-inverting) input
OUT	6	—	Output
REF	5	—	Reference input. This pin internally connects to a reference buffer amplifier in G = 1, unity gain follower configuration.
GS	1	I	Gain select – logic low (G = 10 for INA351ABS and G = 30 for INA351CDS) Gain select – logic high (G = 20 for INA351ABS and G = 50 for INA351CDS) Gain select – no connect (G = 20 for INA351ABS and G = 50 for INA351CDS)
SHDN	8	I	Shutdown – logic high (device enabled) Shutdown – logic low (device disabled) Shutdown – no connect (device enabled)
V–	4	—	Negative supply
V+	7	—	Positive supply
