TMP121AIDBVR

Texas Instruments · Temperature Sensors · SOT-23-6

TMP121AIDBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No Connection pin that may be left floating or connected to GND.
2 GND power_in Ground power supply return, thermally connected to die flag.
3 V+ power_in Power supply input with operating range 2.7V to 5.5V, with 0.1µF bypass capacitor to GND recommended.
4 SCK input Serial clock input for SPI interface accepting logic levels with VIH ≥ 0.7V+, VIL ≤ 0.3V+, maximum input current ±1µA.
5 CS input Chip select input (active low) pulling low to initiate temperature data read and terminate active conversion, accepting logic levels with VIH ≥ 0.7V+, VIL ≤ 0.3V+, maximum input current ±1µA.
6 SO output Serial data output transmitting 12-bit plus sign temperature data on falling SCK edge with VOL = 0.4V at 3mA and VOH = V+ - 0.4V at 2mA.
