ALM2403QPWPRQ1 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 op amp input for channel 1. |
| 2 | IN1+ | input | Noninverting op amp input for channel 1. |
| 3 | OTF/SH_DN | bidirectional | Overtemperature flag and shutdown; high (≥1.2 V) enables operation, low (≤0.5 V) initiates low IQ shutdown state. |
| 4 | IN2+ | input | Noninverting op amp input for channel 2. |
| 5 | IN2- | input | Inverting op amp input for channel 2. |
| 6 | V- | power_in | Negative supply pin; must be connected together with pin 14. |
| 7 | NC | unconnected | No internal connection; do not connect. |
| 8 | NC | unconnected | No internal connection; do not connect. |
| 9 | OUT2 | output | Op amp output for channel 2; sources 500 mA and sinks 400 mA peak at 25°C. |
| 10 | V+ | power_in | Positive supply pin; voltage range 5 to 24 V. |
| 11 | V+ | power_in | Positive supply pin; voltage range 5 to 24 V. |
| 12 | V+ | power_in | Positive supply pin; voltage range 5 to 24 V. |
| 13 | OUT1 | output | Op amp output for channel 1; sources 500 mA and sinks 400 mA peak at 25°C. |
| 14 | V- | power_in | Negative supply pin; must be connected together with pin 6. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
