GS8042-SR from Gainsil, 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 | OUTA | output | Amplifier A output. Rail-to-rail output stage; can swing to within ~50mV of either supply rail into light resistive loads (>50kΩ) and source/sink up to 20mA into a 10Ω load to VS/2. |
| 2 | INA- | input | Amplifier A inverting input. High-impedance CMOS input (1pA typ bias current). Input common-mode range extends from VSS-0.1V to VDD+0.1V. |
| 3 | INA+ | input | Amplifier A non-inverting input. High-impedance CMOS input (1pA typ bias current). Input common-mode range extends from VSS-0.1V to VDD+0.1V. |
| 4 | VSS | power_in | Negative supply / ground. In single-supply operation tie to GND; in dual-supply operation tie to the negative rail (down to -2.75V). Absolute max VDD-VSS = 7.5V. |
| 5 | INB+ | input | Amplifier B non-inverting input. High-impedance CMOS input (1pA typ bias current). Input common-mode range extends from VSS-0.1V to VDD+0.1V. |
| 6 | INB- | input | Amplifier B inverting input. High-impedance CMOS input (1pA typ bias current). Input common-mode range extends from VSS-0.1V to VDD+0.1V. |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail output stage; can swing to within ~50mV of either supply rail into light resistive loads (>50kΩ) and source/sink up to 20mA into a 10Ω load to VS/2. |
| 8 | VDD | power_in | Positive supply. Operating range 1.4V to 5.5V (absolute max 7.5V VDD-VSS). Bypass with a 0.1µF ceramic capacitor placed close to the pin. Quiescent current is 600nA/amplifier typ. |
