GS8054-TR

Gainsil · Operational Amplifier · TSSOP-14

GS8054-TR from Gainsil, in a TSSOP-14. 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 CMOS output stage; typical swing to within ~30 mV of the supply rail into 150 Ω and ~8 mV into >1 kΩ. Output current 80 mA typ / 60 mA min. Closed-loop output impedance ~0.08 Ω at f<100 kHz.
2 INA- input Amplifier A inverting input. High-impedance CMOS input (input bias current ~1 pA typ). Absolute input range Vss-0.5 V to VDD+0.5 V; recommended common-mode range -0.2 V to +3.8 V on a 5 V supply.
3 INA+ input Amplifier A non-inverting input. High-impedance CMOS input (IB ~1 pA typ, IOS ~2 pA typ). Same absolute and common-mode range as INA-.
4 VDD power_in Positive supply rail for all four amplifiers. Operating range +2.5 V to +5.5 V (single supply) or +1.25 V to +2.75 V (with matching VSS for dual supply). Absolute max VDD-VSS = 7.5 V. Decouple with a 0.1 µF ceramic close to the pin.
5 INB+ input Amplifier B non-inverting input. High-impedance CMOS input, same electrical characteristics as INA+.
6 INB- input Amplifier B inverting input. High-impedance CMOS input, same electrical characteristics as INA-.
7 OUTB output Amplifier B output. Rail-to-rail CMOS output stage with the same drive characteristics as OUTA.
8 OUTC output Amplifier C output. Rail-to-rail CMOS output stage with the same drive characteristics as OUTA.
9 INC- input Amplifier C inverting input. High-impedance CMOS input, same electrical characteristics as INA-.
10 INC+ input Amplifier C non-inverting input. High-impedance CMOS input, same electrical characteristics as INA+.
11 VSS power_in Negative supply / ground return for all four amplifiers. Tie to GND for single-supply operation, or to the negative rail (down to -2.75 V) for split-supply operation. Decouple with a 0.1 µF ceramic in dual-supply mode.
12 IND+ input Amplifier D non-inverting input. High-impedance CMOS input, same electrical characteristics as INA+.
13 IND- input Amplifier D inverting input. High-impedance CMOS input, same electrical characteristics as INA-.
14 OUTD output Amplifier D output. Rail-to-rail CMOS output stage with the same drive characteristics as OUTA.
