OPA2277M

HGSEMI · Precision Op Amps · SOP-8

OPA2277M from HGSEMI, in a SOP-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 channel A; the datasheet specifies a continuous short-circuit rating (one amplifier per package, short to ground).
2 -In A input Inverting input of channel A; input voltage must stay within (V-) - 0.7 V to (V+) + 0.7 V per the absolute maximum ratings.
3 +In A input Noninverting input of channel A; input voltage must stay within (V-) - 0.7 V to (V+) + 0.7 V per the absolute maximum ratings.
4 V- power_in Negative (lowest) power supply; total supply Vs = (V+) - (V-) is specified from 4 V (±2 V) to 32 V (±16 V).
5 +In B input Noninverting input of channel B; input voltage must stay within (V-) - 0.7 V to (V+) + 0.7 V per the absolute maximum ratings.
6 -In B input Inverting input of channel B; input voltage must stay within (V-) - 0.7 V to (V+) + 0.7 V per the absolute maximum ratings.
7 Out B output Output of channel B; the datasheet specifies a continuous short-circuit rating (one amplifier per package, short to ground).
8 V+ power_in Positive (highest) power supply; total supply Vs = (V+) - (V-) is specified from 4 V (±2 V) to 32 V (±16 V).
