Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Amplifier A rail-to-rail output, with 70mA typical output short-circuit current. |
| 2 | -IN A | input | Amplifier A inverting input; input range -0.1V to 5.6V at Vs=5.5V and diode-clamped to the supply rails (limit to 10mA). |
| 3 | +IN A | input | Amplifier A non-inverting input; input range -0.1V to 5.6V at Vs=5.5V and diode-clamped to the supply rails (limit to 10mA). |
| 4 | V- | power_in | Negative supply, ground in single-supply use; supply V+ to V- is 2.5V to 5.5V (7.0V absolute maximum). |
| 5 | +IN B | input | Amplifier B non-inverting input; input range -0.1V to 5.6V at Vs=5.5V and diode-clamped to the supply rails (limit to 10mA). |
| 6 | -IN B | input | Amplifier B inverting input; input range -0.1V to 5.6V at Vs=5.5V and diode-clamped to the supply rails (limit to 10mA). |
| 7 | OUT B | output | Amplifier B rail-to-rail output, with 70mA typical output short-circuit current. |
| 8 | V+ | power_in | Positive supply, 2.5V to 5.5V operating (7.0V absolute maximum), with a 0.1uF capacitor placed closely across the supply pins. |
