**GTIC** · Precision OpAmps · SOT-23-5

GT8501S5 from GTIC, in a SOT-23-5. 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 | OUT | output | Amplifier output, rail-to-rail, with short-circuit current specified at 10 mA. |
| 2 | V- | power_in | Negative (lowest) power supply; the device operates from 1.8 V to 5.5 V single supply with Vs=(V+)-(V-). |
| 3 | +IN | input | Positive (noninverting) input with common-mode range from (V-)-0.1 V to (V+)+0.1 V. |
| 4 | -IN | input | Negative (inverting) input with common-mode range from (V-)-0.1 V to (V+)+0.1 V. |
| 5 | V+ | power_in | Positive (highest) power supply; Vs=(V+)-(V-) must not exceed the 6.5 V absolute maximum. |
