LM2902Q4T from STMicroelectronics, in a QFN-16-EP(3x3). 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 | IN1+ | input | Non-inverting input of op-amp 1. Common-mode input range includes the negative rail up to (VCC+)-1.5 V; low input bias current (~20 nA typ). |
| 2 | VCC+ | power_in | Positive supply rail. Single-supply operation 3 V to 30 V, or +1.5 V to +15 V split supply. Absolute maximum 32 V. |
| 3 | NC | unconnected | No internal connection. Present on QFN16 3x3 only (added for package symmetry vs. the SO14/TSSOP14 pinout). |
| 4 | IN2+ | input | Non-inverting input of op-amp 2. Common-mode input range includes the negative rail up to (VCC+)-1.5 V. |
| 5 | IN2- | input | Inverting input of op-amp 2. Low input bias current (~20 nA typ), input offset current ~2 nA. |
| 6 | OUT2 | output | Op-amp 2 output. Output swing to within ~20 mV of the negative rail (single-supply); short-circuit current limited to ~20 mA typ. |
| 7 | OUT3 | output | Op-amp 3 output. Output swing to within ~20 mV of the negative rail (single-supply); short-circuit current limited to ~20 mA typ. |
| 8 | IN3- | input | Inverting input of op-amp 3. Low input bias current (~20 nA typ). |
| 9 | IN3+ | input | Non-inverting input of op-amp 3. Common-mode input range includes the negative rail up to (VCC+)-1.5 V. |
| 10 | NC | unconnected | No internal connection. Present on QFN16 3x3 only (added for package symmetry vs. the SO14/TSSOP14 pinout). |
| 11 | VCC- | power_in | Negative supply rail / ground for single-supply operation. Tie to GND for 3 V-30 V single-supply, or -1.5 V to -15 V for split-supply operation. |
| 12 | IN4+ | input | Non-inverting input of op-amp 4. Common-mode input range includes the negative rail up to (VCC+)-1.5 V. |
| 13 | IN4- | input | Inverting input of op-amp 4. Low input bias current (~20 nA typ). |
| 14 | OUT4 | output | Op-amp 4 output. Output swing to within ~20 mV of the negative rail (single-supply); short-circuit current limited to ~20 mA typ. |
| 15 | OUT1 | output | Op-amp 1 output. Output swing to within ~20 mV of the negative rail (single-supply); short-circuit current limited to ~20 mA typ. |
| 16 | IN1- | input | Inverting input of op-amp 1. Low input bias current (~20 nA typ), input offset current ~2 nA. |
| EP | EP | power_in | Exposed thermal pad on the QFN16 3x3 underside. Per datasheet note, may be connected to VCC- or left floating. Connecting to VCC- is recommended for improved thermal dissipation. |
