Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Output of amplifier A; the datasheet rates the output short-circuit condition as continuous and lists ISC as ±45 mA. |
| 2 | -INA | input | Inverting input of amplifier A; signal input voltage must stay between VS- - 0.3 V and VS+ + 0.3 V, with input current limited to ±10 mA. |
| 3 | +INA | input | Non-inverting input of amplifier A; the rail-to-rail input range extends 100 mV beyond each supply rail, and input current is limited to ±10 mA. |
| 4 | -VS | power_in | Negative (lowest) power supply; the operating supply range is 1.8 V to 5.5 V (VS+ to VS-), with an absolute maximum of 10.0 V. |
| 5 | +INB | input | Non-inverting input of amplifier B; the rail-to-rail input range extends 100 mV beyond each supply rail, and input current is limited to ±10 mA. |
| 6 | -INB | input | Inverting input of amplifier B; signal input voltage must stay between VS- - 0.3 V and VS+ + 0.3 V, with input current limited to ±10 mA. |
| 7 | OUTB | output | Output of amplifier B; the datasheet rates the output short-circuit condition as continuous and lists ISC as ±45 mA. |
| 8 | +VS | power_in | Positive (highest) power supply; the operating supply range is 1.8 V to 5.5 V (VS+ to VS-), with an absolute maximum of 10.0 V. |
