## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Output 1 | output | Amplifier 1 output. All-NPN output stage sourcing/sinking up to 30 mA typ (10 mA source / 20 mA sink min short-circuit). Swings to within ~1.0 V of VCC and ~0.3 V of VEE with 10 kΩ load. |
| 2 | In-1 | input | Amplifier 1 inverting input. Bipolar Darlington input; IIB ≈ 100 nA typ, differential input resistance ~150 MΩ, input capacitance ~2.5 pF. |
| 3 | In+1 | input | Amplifier 1 non-inverting input. Common-mode range includes VEE up to (VCC − 1.8 V); do not exceed VCC or drive below VEE − 0.3 V. |
| 4 | VCC | power_in | Positive supply rail. Single-supply operation 3.0 V to 44 V, or split supplies with VCC + |VEE| ≤ 44 V. Supply current ≈ 1.9 mA typ per amplifier (7.6 mA typ total for the quad) at ±15 V. Bypass with a decoupling capacitor immediately adjacent to the pin. |
| 5 | In+2 | input | Amplifier 2 non-inverting input. Same VICR/IIB characteristics as amplifier 1. |
| 6 | In-2 | input | Amplifier 2 inverting input. Bipolar Darlington input; IIB ≈ 100 nA typ. |
| 7 | Output 2 | output | Amplifier 2 output. All-NPN output stage, 30 Ω typ open-loop output impedance at 1 MHz; drives 0 pF to 10,000 pF capacitive loads without oscillation in unity gain. |
| 8 | Output 3 | output | Amplifier 3 output. All-NPN output stage; 20 mA min sink capability typically to (VEE + 1.8 V). |
| 9 | In-3 | input | Amplifier 3 inverting input. Bipolar Darlington input stage; ESD-protected input diodes/clamps. |
| 10 | In+3 | input | Amplifier 3 non-inverting input. Common-mode input voltage range VEE to (VCC − 1.8 V) at 25 °C. |
| 11 | VEE | power_in | Negative supply / ground return. Tie to ground for single-supply operation (3.0 V to 44 V at VCC) or to a negative rail for split supplies. VCC to VEE differential must not exceed +44 V. |
| 12 | In+4 | input | Amplifier 4 non-inverting input. Same input characteristics as the other channels. |
| 13 | In-4 | input | Amplifier 4 inverting input. Bipolar Darlington input; VIO ≤ 3.0 mV max (A suffix) at 25 °C. |
| 14 | Output 4 | output | Amplifier 4 output. All-NPN output stage; short-circuit protected indefinitely to ground at ±15 V supplies. |
