OPA2227P

Texas Instruments · Precision Op Amps · PDIP-8

OPA2227P from Texas Instruments, in a PDIP-8. 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 of amplifier channel A.
2 -In A input Inverting input of channel A.
3 +In A input Non-inverting input of channel A.
4 V- power_in Negative (lowest) power supply; recommended dual supply is ±2.25 V to ±18 V (single supply 4.5 V to 36 V).
5 +In B input Non-inverting input of channel B.
6 -In B input Inverting input of channel B.
7 Out B output Output of amplifier channel B.
8 V+ power_in Positive (highest) power supply; see V- for the recommended supply range of ±2.25 V to ±18 V (single supply 4.5 V to 36 V).
