HG2277M from HGSEMI, in a SOP-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 | Out A | output | Output of amplifier channel A. Drives ±35 mA short-circuit current; can swing to (V-)+2 V / (V+)-2 V into 10 kΩ, or (V-)+3 V / (V+)-3 V into 2 kΩ. |
| 2 | -In A | input | Inverting input of amplifier channel A. Protected with 1 kΩ series resistor and diode clamps; withstands ±30 V differential. Common-mode range (V-)+2 V to (V+)-2 V. |
| 3 | +In A | input | Noninverting input of amplifier channel A. Protected with 1 kΩ series resistor and diode clamps; withstands ±30 V differential. Common-mode range (V-)+2 V to (V+)-2 V. |
| 4 | V- | power_in | Negative (lowest) power supply. Operating range ±2 V to ±18 V (total 4 V to 36 V); specified over ±5 V to ±15 V. Bypass with 0.1 μF close to the pin for noisy supplies. |
| 5 | +In B | input | Noninverting input of amplifier channel B. Protected with 1 kΩ series resistor and diode clamps; withstands ±30 V differential. Common-mode range (V-)+2 V to (V+)-2 V. |
| 6 | -In B | input | Inverting input of amplifier channel B. Protected with 1 kΩ series resistor and diode clamps; withstands ±30 V differential. Common-mode range (V-)+2 V to (V+)-2 V. |
| 7 | Out B | output | Output of amplifier channel B. Drives ±35 mA short-circuit current; can swing to (V-)+2 V / (V+)-2 V into 10 kΩ, or (V-)+3 V / (V+)-3 V into 2 kΩ. |
| 8 | V+ | power_in | Positive (highest) power supply. Operating range ±2 V to ±18 V (total 4 V to 36 V); specified over ±5 V to ±15 V. Bypass with 0.1 μF close to the pin for noisy supplies. |
