TMP20AIDCKR

Texas Instruments · Temperature and Humidity Sensor · SC-70-5

TMP20AIDCKR from Texas Instruments, in a SC-70-5. 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 internal connection. Must be grounded or left floating. See Layout Example for recommended handling.
2 NC/GND passive No internal connection. Must be grounded or left floating. For best thermal response, connect to the GND plane. Do not attempt to connect this pin to any electrical potential other than GND - the substrate is directly connected to this pad through conductive epoxy.
3 VOUT output Analog voltage output proportional to die temperature. Linear transfer function with -11.77 mV/°C (typical) slope and 1.8639 V (typical) at 0°C.
4 V+ power_in Positive supply voltage input. Operating range 2.7 V to 5.5 V (1.8 V to 5.5 V for T ≥ 15°C); absolute maximum 7 V. Bypass with a local decoupling capacitor. When V+ < 0.5 V the device enters shutdown (<20 nA typical).
5 GND power_in Ground reference / negative supply pin.
