TSZ124IQ4T

STMicroelectronics · Precision Op Amps · QFN-16-EP(3x3)

TSZ124IQ4T from STMicroelectronics, in a QFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN1+ input Non-inverting input of amplifier 1, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V.
2 VCC+ power_in Positive supply, 1.8 V to 5.5 V operating range (6 V absolute maximum), decoupled with a 0.1 µF capacitor close to the pin.
3 NC unconnected No internal connection.
4 IN2+ input Non-inverting input of amplifier 2, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V.
5 IN2- input Inverting input of amplifier 2; input current must be limited to 10 mA by a series resistor.
6 OUT2 output Output of amplifier 2, rail-to-rail swinging within 30 mV of the rails with a 10 kΩ load.
7 OUT3 output Output of amplifier 3, rail-to-rail swinging within 30 mV of the rails with a 10 kΩ load.
8 IN3- input Inverting input of amplifier 3; input current must be limited to 10 mA by a series resistor.
9 IN3+ input Non-inverting input of amplifier 3, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V.
10 NC unconnected No internal connection.
11 VCC- power_in Negative supply (ground reference for single-supply operation).
12 IN4+ input Non-inverting input of amplifier 4, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V.
13 IN4- input Inverting input of amplifier 4; input current must be limited to 10 mA by a series resistor.
14 OUT4 output Output of amplifier 4, rail-to-rail swinging within 30 mV of the rails with a 10 kΩ load.
15 OUT1 output Output of amplifier 1, rail-to-rail swinging within 30 mV of the rails with a 10 kΩ load.
16 IN1- input Inverting input of amplifier 1; input current must be limited to 10 mA by a series resistor.
17 EP passive Exposed pad, marked NC in the pinout; the datasheet says it can be connected to VCC- or left floating.
