Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output. Rail-to-rail output; swings to within ~5mV of the supply rails at light resistive loads (>100kΩ) and within ~20mV at 10kΩ. Short-circuit current typically 20mA source/sink. |
| 2 | INA- | input | Amplifier A inverting input. Rail-to-rail input; common-mode range extends 100mV beyond supply rails (VSS-0.1V to VDD+0.1V). Very low input bias current (~20pA typ). |
| 3 | INA+ | input | Amplifier A non-inverting input. Rail-to-rail input (VSS-0.1V to VDD+0.1V common-mode range). Absolute maximum: VSS-0.5V to VDD+0.5V. |
| 4 | VDD | power_in | Positive supply. Single-supply operation from +1.8V to +5.5V (or dual ±0.9V to ±2.75V). Absolute maximum VDD-VSS = 7.5V. Bypass to VSS with a 0.1µF ceramic capacitor placed close to this pin. |
| 5 | INB+ | input | Amplifier B non-inverting input. Rail-to-rail input (VSS-0.1V to VDD+0.1V common-mode range). |
| 6 | INB- | input | Amplifier B inverting input. Rail-to-rail input; very low input bias current (~20pA typ). |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail; swings to within ~5mV of supply rails at light loads (>100kΩ), ~20mV at 10kΩ. Short-circuit current typically 20mA source/sink. |
| 8 | OUTC | output | Amplifier C output. Rail-to-rail; swings to within ~5mV of supply rails at light loads (>100kΩ), ~20mV at 10kΩ. Short-circuit current typically 20mA source/sink. |
| 9 | INC- | input | Amplifier C inverting input. Rail-to-rail input; very low input bias current (~20pA typ). |
| 10 | INC+ | input | Amplifier C non-inverting input. Rail-to-rail input (VSS-0.1V to VDD+0.1V common-mode range). |
| 11 | VSS | power_in | Negative supply / ground. Tie to GND for single-supply operation, or to the negative rail for dual-supply operation. Absolute maximum VDD-VSS = 7.5V. Bypass with a 0.1µF ceramic capacitor for dual-supply use. |
| 12 | IND+ | input | Amplifier D non-inverting input. Rail-to-rail input (VSS-0.1V to VDD+0.1V common-mode range). |
| 13 | IND- | input | Amplifier D inverting input. Rail-to-rail input; very low input bias current (~20pA typ). |
| 14 | OUTD | output | Amplifier D output. Rail-to-rail; swings to within ~5mV of supply rails at light loads (>100kΩ), ~20mV at 10kΩ. Short-circuit current typically 20mA source/sink. |
