Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connect pin, marked NC in the datasheet pin figure and not assigned a function. |
| 2 | -IN | input | Inverting input; the datasheet specifies an input voltage range of 0 V to 5 V at VS = 5 V and 0 V to 2.7 V at VS = 2.7 V, with absolute maximum input voltage of VSS − 0.3 V to VDD + 0.3 V. |
| 3 | +IN | input | Non-inverting input; the datasheet specifies an input voltage range of 0 V to 5 V at VS = 5 V and 0 V to 2.7 V at VS = 2.7 V, with absolute maximum input voltage of VSS − 0.3 V to VDD + 0.3 V. |
| 4 | V- | power_in | Negative supply; the part is fully specified for single-supply operation from 2.7 V to 5.0 V or dual supply of ±1.35 V to ±2.5 V, with absolute maximum supply voltage of +6 V. |
| 5 | NC | unconnected | No connect pin, marked NC in the datasheet pin figure and not assigned a function. |
| 6 | OUT | output | Amplifier output; the datasheet gives a short-circuit limit (ISC) of ±25 mA at VS = 5 V and ±8 mA at VS = 2.7 V. |
| 7 | V+ | power_in | Positive supply; the part is fully specified for single-supply operation from 2.7 V to 5.0 V, with absolute maximum supply voltage of +6 V. |
| 8 | NC | unconnected | No connect pin, marked NC in the datasheet pin figure and not assigned a function. |
