## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output, channel A of the dual-channel precision operational amplifier. |
| 2 | -IN A | input | Inverting input, channel A; part of the rail-to-rail input stage. |
| 3 | +IN A | input | Noninverting input, channel A; part of the rail-to-rail input stage. |
| 4 | V- | power_in | Negative (lowest) power supply; operating range ±1.25 V to ±2.75 V dual-supply, or 2.5 V to 5.5 V single-supply. |
| 5 | +IN B | input | Noninverting input, channel B; part of the rail-to-rail input stage. |
| 6 | -IN B | input | Inverting input, channel B; part of the rail-to-rail input stage. |
| 7 | OUT B | output | Output, channel B of the dual-channel precision operational amplifier. |
| 8 | V+ | power_in | Positive (highest) power supply; operating range ±1.25 V to ±2.75 V dual-supply, or 2.5 V to 5.5 V single-supply. |
