LM2902Q4T

STMicroelectronics · Operational Amplifier · QFN-16-EP(3x3)

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.
