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. |
