UMW · Precision Op Amps · SOT-23-5
ADA4051-1ARJZ from UMW, in a SOT-23-5. 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 | OUT | output | Rail-to-rail output with 1 Ω output impedance; withstands indefinite short-circuit to supply rails with 13 mA short-circuit current. |
| 2 | V- | power_in | Negative supply rail and circuit ground reference for single-supply (1.8 V to 5.5 V) operation. |
| 3 | +IN | input | Non-inverting input; accepts input voltage 0 to VSY with 8 MΩ differential input impedance and 250 GΩ common-mode impedance; 5-50 pA typical input bias current. |
| 4 | -IN | input | Inverting input; accepts input voltage 0 to VSY with 8 MΩ differential input impedance and 250 GΩ common-mode impedance; 5-50 pA typical input bias current. |
| 5 | V+ | power_in | Positive supply; operating range 1.8 V to 5.5 V with 15-18 μA supply current. |
