PIN TYPE(1) DESCRIPTION
NAME NO.
IN– 2 I Negative (inverting) input
IN+ 3 O Positive (noninverting) 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
