LM2902MT from HGSEMI, in a TSSOP-14. 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. Push-pull output stage capable of ~40mA short-circuit current at VCC=+15V; sink current 20mA typ (Vid=-1V, Vo=+2V). |
| 2 | IN1- | input | Inverting input of op-amp 1. High-impedance input; input bias current 20nA typ, input offset 2mV typ. Input common-mode range 0 V to VCC-1.5V. |
| 3 | IN1+ | input | Non-inverting input of op-amp 1. High-impedance input; input bias current 20nA typ. Common-mode range includes ground. |
| 4 | VCC+ | power_in | Positive supply pin. Single-supply +3V to +30V, or +1.5V to +15V for split supplies. Absolute max ±16 to 32V; total supply current 0.7mA typ (all amps, no load, VCC=+5V). |
| 5 | IN2+ | input | Non-inverting input of op-amp 2. High-impedance input; common-mode range includes ground. |
| 6 | IN2- | input | Inverting input of op-amp 2. High-impedance input; input bias current 20nA typ. |
| 7 | OUT2 | output | Output of op-amp 2. Push-pull output; ~40mA short-circuit source current at VCC=+15V. |
| 8 | OUT3 | output | Output of op-amp 3. Push-pull output; ~40mA short-circuit source current at VCC=+15V. |
| 9 | IN3- | input | Inverting input of op-amp 3. High-impedance input; input bias current 20nA typ. |
| 10 | IN3+ | input | Non-inverting input of op-amp 3. High-impedance input; common-mode range includes ground. |
| 11 | VCC- | power_in | Negative supply / ground pin. Tie to GND for single-supply operation, or to a negative rail (down to -15V) for split-supply operation. |
| 12 | IN4+ | input | Non-inverting input of op-amp 4. High-impedance input; common-mode range includes ground. |
| 13 | IN4- | input | Inverting input of op-amp 4. High-impedance input; input bias current 20nA typ. |
| 14 | OUT4 | output | Output of op-amp 4. Push-pull output; ~40mA short-circuit source current at VCC=+15V. |
