OPA211AIDR

Texas Instruments · Precision OpAmps · SOIC-8

OPA211AIDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No internal connection. May be left floating or tied to any voltage between V- and V+.
2 -IN input Inverting input of the op-amp. Common-mode input range extends to (V-)+1.5 V and up to (V+)-2 V; input bias current typ ±60 nA.
3 +IN input Non-inverting input of the op-amp. Common-mode input range extends to (V-)+1.5 V and up to (V+)-2 V; input bias current typ ±60 nA.
4 V- power_in Negative supply rail. Operates from -18 V to -2.25 V for split supplies, or 0 V (GND) for single-supply operation up to 36 V total across V+ and V-. Bypass to V+ with 0.1 µF ceramic close to the pins.
5 NC unconnected No internal connection. May be left floating or tied to any voltage between V- and V+.
6 OUT output Rail-to-rail amplifier output. Sources/sinks up to ±30 mA short-circuit; output swings to within ~600 mV of each rail at 10 mA load. Slew rate 27 V/µs.
7 V+ power_in Positive supply rail. Operates from +2.25 V to +18 V for split supplies, or 4.5 V to 36 V single-supply (referenced to V-). Bypass to V- with 0.1 µF ceramic close to the pins. Typical supply current 3.6 mA per channel.
8 Shutdown input Active-high shutdown control. Device enabled when (V-) ≤ V_SHUTDOWN ≤ (V+)-3 V; device disabled when V_SHUTDOWN ≥ (V+)-0.35 V. Reduces supply current when asserted.
