Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUT1 | output | Output of op-amp 1. Class-AB stage; short-circuit protected to ground (Isc typ 40 mA). Output swings from VEE up to VCC-1.5 V typical. |+| 2 | IN1- | input | Inverting input of op-amp 1. High-impedance BJT input; typical input bias current -90 nA (max -250 nA at 25 °C for LM2902). |+| 3 | IN1+ | input | Non-inverting input of op-amp 1. Common-mode range extends to VEE (0 V) up to VCC-1.7 V. Absolute input voltage tolerated up to +32 V and down to -0.3 V. |+| 4 | VCC | power_in | Positive supply rail. Single-supply operation 3.0 V to 32 V, or split-supply +1.5 V to +16 V. Quiescent current typically 0.7 mA at VCC = 5 V (all four amps). |+| 5 | IN2+ | input | Non-inverting input of op-amp 2. See IN1+ for common-mode range and absolute limits. |+| 6 | IN2- | input | Inverting input of op-amp 2. Typical input bias current -90 nA. |+| 7 | OUT2 | output | Output of op-amp 2. Short-circuit protected; source ~40 mA / sink ~20 mA typical at VCC = 15 V. |+| 8 | OUT3 | output | Output of op-amp 3. Short-circuit protected to ground; class-AB output stage. |+| 9 | IN3- | input | Inverting input of op-amp 3. |+| 10 | IN3+ | input | Non-inverting input of op-amp 3. |+| 11 | VEE/GND | power_in | Negative supply rail. Tie to GND for single-supply operation (VCC up to 32 V), or to a negative rail down to -16 V for split supplies. |+| 12 | IN4+ | input | Non-inverting input of op-amp 4. |+| 13 | IN4- | input | Inverting input of op-amp 4. |+| 14 | OUT4 | output | Output of op-amp 4.
