GT3140ADTR

XBLW · Operational Amplifier · SOP-8

GT3140ADTR from XBLW, in a SOP-8. 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 OA1 passive Offset null terminal (OFFSET NULL) used to trim input offset voltage.
2 IN- input Inverting input of the operational amplifier.
3 IN+ input Non-inverting input of the operational amplifier.
4 V- power_in Negative power supply.
5 OA2 passive Offset null terminal (OFFSET NULL) used to trim input offset voltage.
6 OUT output Amplifier output.
7 V+ power_in Positive power supply.
8 ST input Strobe pin (labelled STROBE in the diagram).
