GS8634-TR

Gainsil · Operational Amplifier · TSSOP-14

GS8634-TR from Gainsil, in a TSSOP-14. 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 Amplifier A output, rail-to-rail swing.
2 INA- input Amplifier A inverting input; common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
3 INA+ input Amplifier A non-inverting input; common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
4 VDD power_in Positive supply, 2.1V to 5.5V (absolute max 7.5V above VSS); bypass with a 0.1µF ceramic capacitor close to the pin.
5 INB+ input Amplifier B non-inverting input; common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
6 INB- input Amplifier B inverting input; common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
7 OUTB output Amplifier B output, rail-to-rail swing.
8 OUTC output Amplifier C output, rail-to-rail swing.
9 INC- input Amplifier C inverting input; common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
10 INC+ input Amplifier C non-inverting input; common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
11 VSS power_in Negative supply or ground; for dual-supply operation bypass with a separate 0.1µF ceramic capacitor.
12 IND+ input Amplifier D non-inverting input; common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
13 IND- input Amplifier D inverting input; common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
14 OUTD output Amplifier D output, rail-to-rail swing.
