GM45002ARZ-R7 from GONGMOSEMI, in a SOIC-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 | OUTA | output | Output of amplifier A; the datasheet gives the output current as ±220 mA at VS=±2.5 V and ±50 mA at VS=2.7 V (VOUT=±0.5 V). |
| 2 | -INA | input | Inverting input of amplifier A; the input voltage should not exceed the supply by more than 0.3 V, and the input current should be limited to less than 5 mA with a series resistor if a higher input voltage is applied. |
| 3 | +INA | input | Non-inverting input of amplifier A; the input common-mode range is 0 V to 5 V, and the input should not exceed the supply by more than 0.3 V (input current limited to less than 5 mA). |
| 4 | V- | power_in | Negative power supply terminal; the device operates from a 2.7 V to 5.5 V single supply or ±1.35 V to ±2.75 V split supply, with an absolute maximum V+ to V- of 6 V. |
| 5 | +INB | input | Non-inverting input of amplifier B; the input common-mode range is 0 V to 5 V, and the input should not exceed the supply by more than 0.3 V (input current limited to less than 5 mA). |
| 6 | -INB | input | Inverting input of amplifier B; the input voltage should not exceed the supply by more than 0.3 V, and the input current should be limited to less than 5 mA with a series resistor if a higher input voltage is applied. |
| 7 | OUTB | output | Output of amplifier B; the datasheet gives the output current as ±220 mA at VS=±2.5 V and ±50 mA at VS=2.7 V (VOUT=±0.5 V). |
| 8 | V+ | power_in | Positive power supply terminal; the device operates from 2.7 V to 5.5 V, with an absolute maximum V+ to V- of 6 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
