| 3 | IN A+ | input | Amplifier A non-inverting input, common mode range extends 200 mV below V-. |
| 4 | V+ | power_in | Positive supply, 1.6V to 5.5V operating range relative to V-, 6V absolute maximum. |
| 5 | IN B+ | input | Amplifier B non-inverting input, common mode range extends 200 mV below V-. |
| 6 | IN B- | input | Amplifier B inverting input, CMOS high impedance with ±20 fA typical bias current. |
| 7 | OUT B | output | Amplifier B output, rail-to-rail swinging within 15 mV of the supply. |
| 8 | OUT C | output | Amplifier C output, rail-to-rail swinging within 15 mV of the supply. |
| 9 | IN C- | input | Amplifier C inverting input, CMOS high impedance with ±20 fA typical bias current. |
| 10 | IN C+ | input | Amplifier C non-inverting input, common mode range extends 200 mV below V-. |
| 11 | V- | power_in | Negative supply (ground in single-supply use), 1.6V to 5.5V total supply range relative to V+. |
| 12 | IN D+ | input | Amplifier D non-inverting input, common mode range extends 200 mV below V-. |
| 13 | IN D- | input | Amplifier D inverting input, CMOS high impedance with ±20 fA typical bias current. |
| 14 | OUT D | output | Amplifier D output, rail-to-rail swinging within 15 mV of the supply. |
