AD8531ARTZ-REEL7 from Analog Devices, 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 A | output | Amplifier output, rail-to-rail, rated for ±250 mA output current, with no internal short-circuit protection so direct connection to the positive supply destroys the device. |
| 2 | V- | power_in | Negative supply rail; the part operates from a 2.7 V to 6 V single supply (3 V and 5 V specified). |
| 3 | +IN A | input | Non-inverting input with rail-to-rail input range; input voltage range is 0 V to 3 V at VS = 3 V with input bias current of 5 pA typical and 50 pA maximum at 25°C. |
| 4 | -IN A | input | Inverting input with low input bias current (5 pA typical, 50 pA maximum at 25°C) and input offset current of 1 pA typical. |
| 5 | V+ | power_in | Positive supply rail; the part operates from a 2.7 V to 6 V single supply (absolute maximum supply and output stability depend on the rating given in the datasheet). |
