| 3 | INA+ | input | Channel A non-inverting input; analog input voltage must stay within Vss-0.5V to VDD+0.5V. |
| 4 | VSS | power_in | Negative supply or ground; VDD to Vss operating range is 2.5V to 5.5V (absolute maximum 7.5V). |
| 5 | INB+ | input | Channel B non-inverting input; analog input voltage must stay within Vss-0.5V to VDD+0.5V. |
| 6 | INB- | input | Channel B inverting input; analog input voltage must stay within Vss-0.5V to VDD+0.5V. |
| 7 | OUTB | output | Channel B amplifier output, rail-to-rail output swing, typically within 0.12V of the rail at RL=150Ω. |
| 8 | VDD | power_in | Positive supply, 2.5V to 5.5V operating (absolute maximum 7.5V relative to Vss), with a 0.1µF ceramic bypass capacitor placed close to the pin. |
