Hot-selling and scarce TMP37GSZ Low Voltage Temperature Sensors SOP8 spot stock

Product Descriptions

The TMP35/TMP36/TMP37 are low voltage, precision centigrade temperature sensors. They provide a voltage output thatis linearly proportional to the Celsius (centigrade) temperature .The TMP35/TMP36/TMP37 do not require any externalcalibration to provide typical accuracies of ±1°C at +25°Cand ±2°C over the −40°C to +125°C temperature range 

The low output impedance of the TMP35/TMP36/TMP37 andits linear output and precise calibration simplify interfacing totemperature control circuitry and ADCs . All three devices areintended for single-supply operation from 2.7 V to 5.5 V maximum. The supply current runs well below 50 µA, providingvery low self-heating—less than 0.1°C in still air. In addition, ashutdown function is provided to cut the supply current to lessthan 0.5 µA .

The TMP35 is functionally compatible with the LM35/LM45and provides a 250 mV output at 25°C . The TMP35 readstemperatures from 10°C to 125°C . The TMP36 is specified from−40°C to +125°C, provides a 750 mV output at 25°C, andoperates to 125°C from a single 2.7 V supply. The TMP36 isfunctionally compatible with the LM50 . Both the TMP35 andTMP36 have an output scale factor of 10 mV/°C .
