Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Out A | output | Output of amplifier A, which swings rail-to-rail between the supply rails. |
| 2 | -In A | input | Inverting input of amplifier A; the input common-mode range extends 100mV beyond V- and V+. |
| 3 | +In A | input | Non-inverting input of amplifier A; the input common-mode range extends 100mV beyond V- and V+. |
| 4 | +VS | power_in | Positive supply (V+); supply range is 2.5V to 5.5V, with absolute maximum supply voltage of 6V. |
| 5 | +In B | input | Non-inverting input of amplifier B; the input common-mode range extends 100mV beyond V- and V+. |
| 6 | -In B | input | Inverting input of amplifier B; the input common-mode range extends 100mV beyond V- and V+. |
| 7 | Out B | output | Output of amplifier B, which swings rail-to-rail between the supply rails. |
| 8 | Out C | output | Output of amplifier C, which swings rail-to-rail between the supply rails. |
| 9 | -In C | input | Inverting input of amplifier C; the input common-mode range extends 100mV beyond V- and V+. |
| 10 | +In C | input | Non-inverting input of amplifier C; the input common-mode range extends 100mV beyond V- and V+. |
| 11 | -VS | power_in | Negative supply (V-), the reference for the input common-mode range and the lower supply rail. |
| 12 | +In D | input | Non-inverting input of amplifier D; the input common-mode range extends 100mV beyond V- and V+. |
| 13 | -In D | input | Inverting input of amplifier D; the input common-mode range extends 100mV beyond V- and V+. |
| 14 | Out D | output | Output of amplifier D, which swings rail-to-rail between the supply rails. |
