OPA2211AIDDA

Texas Instruments · Operational Amplifier · SOP-8-EP

OPA2211AIDDA from Texas Instruments, in a SOP-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT A output Output channel A with voltage swing from (V-) + 0.2V to (V+) - 0.2V at RL = 10kΩ and maximum output current capability of 30mA source or 45mA sink.
2 -IN A input Inverting input channel A with common-mode voltage range from (V-) + 1.8V to (V+) - 1.4V for dual supply voltages ≥ ±5V.
3 +IN A input Non-inverting input channel A with common-mode voltage range from (V-) + 1.8V to (V+) - 1.4V for dual supply voltages ≥ ±5V.
4 V- power_in Negative power supply rail with rated supply voltage range ±2.25V to ±18V (dual supply) or 4.5V to 36V (single supply).
5 +IN B input Non-inverting input channel B with common-mode voltage range from (V-) + 1.8V to (V+) - 1.4V for dual supply voltages ≥ ±5V.
6 -IN B input Inverting input channel B with common-mode voltage range from (V-) + 1.8V to (V+) - 1.4V for dual supply voltages ≥ ±5V.
7 OUT B output Output channel B with voltage swing from (V-) + 0.2V to (V+) - 0.2V at RL = 10kΩ and maximum output current capability of 30mA source or 45mA sink.
8 V+ power_in Positive power supply rail with rated supply voltage range ±2.25V to ±18V (dual supply) or 4.5V to 36V (single supply).
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
