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. |
