Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output of amplifier A, which swings rail to rail (datasheet lists output swing from rail of 31 mV at RL=2kΩ and 7 mV at RL=10kΩ). |
| 2 | -IN A | input | Inverting input of amplifier A; input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10 mA. |
| 3 | +IN A | input | Non-inverting input of amplifier A; common-mode input range is -0.1V to 5.6V at Vs=5.5V. |
| 4 | V+ | power_in | Positive supply pin; operating supply range is 2.5V to 5.5V and the absolute maximum supply voltage V+ to V- is 7.0V. |
| 5 | +IN B | input | Non-inverting input of amplifier B; common-mode input range is -0.1V to 5.6V at Vs=5.5V. |
| 6 | -IN B | input | Inverting input of amplifier B; input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10 mA. |
| 7 | OUT B | output | Output of amplifier B, which swings rail to rail (datasheet lists output swing from rail of 31 mV at RL=2kΩ and 7 mV at RL=10kΩ). |
| 8 | OUT C | output | Output of amplifier C, which swings rail to rail (datasheet lists output swing from rail of 31 mV at RL=2kΩ and 7 mV at RL=10kΩ). |
| 9 | -IN C | input | Inverting input of amplifier C; input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10 mA. |
| 10 | +IN C | input | Non-inverting input of amplifier C; common-mode input range is -0.1V to 5.6V at Vs=5.5V. |
| 11 | V- | power_in | Negative supply pin (ground in single-supply use); operating supply range is 2.5V to 5.5V single-supply or ±1.25V to ±2.75V dual-supply. |
| 12 | +IN D | input | Non-inverting input of amplifier D; common-mode input range is -0.1V to 5.6V at Vs=5.5V. |
| 13 | -IN D | input | Inverting input of amplifier D; input terminals are diode-clamped to the supply rails and signals more than 0.5V beyond the rails should be limited to 10 mA. |
| 14 | OUT D | output | Output of amplifier D, which swings rail to rail (datasheet lists output swing from rail of 31 mV at RL=2kΩ and 7 mV at RL=10kΩ). |
