Pin Functions: OPA211

PIN I/O DESCRIPTION
NAME NO.
+IN 3 I Noninverting input
–IN 2 I Inverting input
NC 1, 5 — No internal connection. This pin can be left floating or connected to any voltage between (V–) and (V+).
OUT 6 O Output
Shutdown 8 I Shutdown, active high
The shutdown function is as follows:

Device enabled: (V–) ≤ VSHUTDOWN ≤ (V+) – 3 V


Device disabled: VSHUTDOWN ≥ (V+) – 0.35 V
V+ 7 I Positive power supply
V– 4 I Negative power supply
Thermal pad — — Exposed thermal die pad on underside; connect thermal die pad to V–. Soldering the thermal pad to the printed circuit board is required and improves heat dissipation and provides specified performance.
