Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | AMPIN+ | input | Non-inverting input of the operational amplifier; common-mode input range is 0 V to VCC. |
| 2 | GND | power_in | Ground reference for the device; all supply and absolute maximum voltages are referenced to this pin. |
| 3 | AMPOUT | output | Operational amplifier output; short-circuit duration to ground or VCC is continuous. |
| 4 | VCC | power_in | Positive supply for the internal circuits, operating from 2.5 V to 5.5 V; absolute maximum VCC to GND is -0.3 V to +6.5 V. |
| 5 | REF | output | Internal voltage reference output, typically 1.205 V with ±2% accuracy; external filter capacitance above 80 pF may make the output unstable. |
| 6 | AMPIN- | input | Inverting input of the operational amplifier; common-mode input range is 0 V to VCC. |
