Texas Instruments · Temperature Sensors · SOIC-8
TMP411ADR from Texas Instruments, in a SOIC-8. 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 | V+ | power_in | Positive supply: 2.7 V to 5.5 V for TMP411 (1.62 V to 5.5 V for TMP411D), with 0.1 µF bypass recommended between V+ and GND placed as close to the device as possible. |
| 2 | D+ | passive | Positive connection to the remote temperature sensor (diode-connected or transistor-connected); if the remote channel is unused, D+ must be tied to D-. |
| 3 | D- | passive | Negative connection to the remote temperature sensor; differential input capacitance between D+ and D- should be 1000 pF or less for best accuracy. |
| 4 | THERM | output | Thermal flag output, active low, open-drain, requires a pullup resistor to V+; it cannot be disabled in software. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | ALERT/THERM2 | output | Alert output (reconfigurable as a second thermal flag, THERM2), active low, open-drain, requires a pullup resistor to V+. |
| 7 | SDA | bidirectional | SMBus/two-wire serial data line, open-drain, requires a pullup resistor to V+. |
| 8 | SCL | input | SMBus/two-wire serial clock line, open-drain, requires a pullup resistor to V+; supports up to 3.4 MHz in high-speed mode. |
