| 4 | V- | power_in | Negative supply; supply voltage range is ±4.5 V to ±18 V. |
| 5 | +IN B | input | Amplifier B non-inverting input; common-mode range guaranteed from -11 V to +15 V at VS = ±15 V. |
| 6 | -IN B | input | Amplifier B inverting input; input voltage must not exceed ±18 V (or the supply voltage if less than ±18 V). |
| 7 | OUT B | output | Amplifier B output. |
| 8 | V+ | power_in | Positive supply; supply voltage range is ±4.5 V to ±18 V. |
