## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output of amplifier A; input/output pin voltage must stay between V- − 0.3 V and V+ + 0.3 V, and continuous output current above 45 mA adversely affects reliability. |
| 2 | -IN A | input | Inverting input of amplifier A; input/output pin voltage must stay between V- − 0.3 V and V+ + 0.3 V, with a common-mode range extending about 200 mV beyond each supply rail at 25 °C. |
| 3 | +IN A | input | Non-inverting input of amplifier A; the input common-mode voltage range extends about 200 mV beyond each supply rail at 25 °C. |
| 4 | V- | power_in | Negative power supply; for single-supply operation this is connected to GND (0 V), and the total supply (V+ − V-) is 1.8 V to 5.5 V recommended with 6 V absolute maximum. |
| 5 | +IN B | input | Non-inverting input of amplifier B; the input common-mode voltage range extends about 200 mV beyond each supply rail at 25 °C. |
| 6 | -IN B | input | Inverting input of amplifier B; input/output pin voltage must stay between V- − 0.3 V and V+ + 0.3 V, with a common-mode range extending about 200 mV beyond each supply rail at 25 °C. |
| 7 | OUT B | output | Output of amplifier B; input/output pin voltage must stay between V- − 0.3 V and V+ + 0.3 V, and continuous output current above 45 mA adversely affects reliability. |
| 8 | V+ | power_in | Positive power supply; recommended supply voltage is 1.8 V to 5.5 V, with 6 V absolute maximum for V+ − V-. |
