**Texas Instruments** · Global Sourcing Parts · HTSSOP-14-EP

ALM2402QPWPRQ1 from Texas Instruments, in a HTSSOP-14-EP. 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 | Inverting input terminal for opamp 1; input common mode range 0.2V to (VCC - 1.2V) per Electrical Characteristics |
| 2 | IN1+ | input | Non-inverting input terminal for opamp 1; input common mode range 0.2V to (VCC - 1.2V) per Electrical Characteristics |
| 3 | OTF/SH_DN | bidirectional | Bidirectional over temperature flag and shutdown pin; pull above 1.0V (VIH_OTF) for normal operation or below 0.35V (VIL_OTF) for shutdown; driven low when junction temperature exceeds 157-175°C |
| 4 | IN2+ | input | Non-inverting input terminal for opamp 2; input common mode range 0.2V to (VCC - 1.2V) per Electrical Characteristics |
| 5 | IN2- | input | Inverting input terminal for opamp 2; input common mode range 0.2V to (VCC - 1.2V) per Electrical Characteristics |
| 6 | GND | power_in | Ground reference pin; both ground pins (6 and 14) must be connected together on PCB board and to exposed thermal pad |
| 7 | NC | unconnected | No internal connection; must not be connected |
| 8 | NC | unconnected | No internal connection; must not be connected |
| 9 | OUT2 | output | Output of opamp 2; can source and sink up to 400mA continuous output current per channel; powered by VCC_O2 (3V to 16V) |
| 10 | VCC_O2 | power_in | Output stage power supply pin for opamp 2; operating range 3V to 16V, independent from VCC |
| 11 | VCC | power_in | Gain stage and protection circuitry power supply for both opamps; operating range 4.5V to 16V |
| 12 | VCC_O1 | power_in | Output stage power supply pin for opamp 1; operating range 3V to 16V, independent from VCC |
| 13 | OUT1 | output | Output of opamp 1; can source and sink up to 400mA continuous output current per channel; powered by VCC_O1 (3V to 16V) |
| 14 | GND | power_in | Ground reference pin; both ground pins (6 and 14) must be connected together on PCB board and to exposed thermal pad |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
