# AD8628ARTZ

**UMW** · Operational Amplifier · SOT-23-5

AD8628ARTZ from UMW, 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 with rail-to-rail swing; output current IO is specified at ±30 mA on a 5 V supply and ±10 mA on a 2.7 V supply. |
| 2 | V- | power_in | Negative supply rail; the part is specified for 2.7 V to 5 V single supply or ±1.35 V to ±2.5 V dual supply. |
| 3 | +IN | input | Non-inverting input with rail-to-rail common-mode range (0 V to VS); if the input exceeds a supply rail by more than 0.3 V, a series resistor must limit the current to less than 5 mA maximum. |
| 4 | -IN | input | Inverting input with rail-to-rail common-mode range (0 V to VS); if the input exceeds a supply rail by more than 0.3 V, a series resistor must limit the current to less than 5 mA maximum. |
| 5 | V+ | power_in | Positive supply rail; the part is fully specified from 2.7 V to 5 V single supply, with PSRR specified over 2.7 V to 5.5 V. |
