## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output of amplifier A, which swings to within a few millivolts of ground while sinking current and needs no pull-down resistor. |
| 2 | -IN A | input | Inverting input of amplifier A, whose input voltage range includes ground in single-supply operation at 5V. |
| 3 | +IN A | input | Non-inverting input of amplifier A, whose input range goes below ground; input voltage must stay within the absolute maximum rating of 5V below the negative supply. |
| 4 | V+ | power_in | Positive supply pin; the absolute maximum supply voltage is ±22V and single-supply operation at 5V is specified, with a minimum supply of 2V. |
| 5 | +IN B | input | Non-inverting input of amplifier B, whose input range goes below ground; input voltage must stay within the absolute maximum rating of 5V below the negative supply. |
| 6 | -IN B | input | Inverting input of amplifier B, whose input voltage range includes ground in single-supply operation at 5V. |
| 7 | OUT B | output | Output of amplifier B, which swings to within a few millivolts of ground while sinking current and needs no pull-down resistor. |
| 8 | OUT D | output | Output of amplifier D, which swings to within a few millivolts of ground while sinking current and needs no pull-down resistor. |
| 9 | -IN D | input | Inverting input of amplifier D, whose input voltage range includes ground in single-supply operation at 5V. |
| 10 | +IN D | input | Non-inverting input of amplifier D, whose input range goes below ground; input voltage must stay within the absolute maximum rating of 5V below the negative supply. |
| 11 | V- | power_in | Negative supply pin, which is 0V in the single-supply 5V configuration; input voltage must not go more than 5V below this pin per the absolute maximum ratings. |
| 12 | +IN C | input | Non-inverting input of amplifier C, whose input range goes below ground; input voltage must stay within the absolute maximum rating of 5V below the negative supply. |
| 13 | -IN C | input | Inverting input of amplifier C, whose input voltage range includes ground in single-supply operation at 5V. |
| 14 | OUT C | output | Output of amplifier C, which swings to within a few millivolts of ground while sinking current and needs no pull-down resistor. |
