Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Output of amplifier A, which swings rail-to-rail and is rated for 30 mA output current with 20 mA short-circuit current (RL = 10 Ω to -VS) per the electrical characteristics. |
| 2 | INA- | input | Inverting input of amplifier A, with analog input voltage limited to VSS-0.5V to VDD+0.5V (absolute maximum rating). |
| 3 | INA+ | input | Non-inverting input of amplifier A, with analog input voltage limited to VSS-0.5V to VDD+0.5V (absolute maximum rating) and a common-mode input range extending 100 mV beyond the supply rails. |
| 4 | VSS | power_in | Negative power supply pin; the device operates from a single supply of 1.8V to 5.5V or a dual supply of ±0.9V to ±2.75V, and the datasheet recommends a 0.1µF ceramic bypass capacitor on the supply pins. |
| 5 | INB+ | input | Non-inverting input of amplifier B, with analog input voltage limited to VSS-0.5V to VDD+0.5V (absolute maximum rating). |
| 6 | INB- | input | Inverting input of amplifier B, with analog input voltage limited to VSS-0.5V to VDD+0.5V (absolute maximum rating). |
| 7 | OUTB | output | Output of amplifier B, which swings rail-to-rail and is rated for 30 mA output current with 20 mA short-circuit current (RL = 10 Ω to -VS) per the electrical characteristics. |
| 8 | VDD | power_in | Positive power supply pin; supply voltage is 1.8V to 5.5V in single-supply operation, with an absolute maximum VDD to VSS of 7.5V. |
