GS8042-SR

Gainsil · Operational Amplifier · SOP-8

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.
