3 Description
The TMP23x devices are a family of precision CMOS
integrated-circuit linear analog temperature sensors
with an output voltage proportional to temperature
engineers can use in multiple analog temperaturesensing
applications. These temperature sensors are
more accurate than similar pin-compatible devices on
the market, featuring typical accuracy from 0°C to
+70°C of ±0.5°C. The increased accuracy of the
series is designed for many analog temperaturesensing
applications.The TMP235 device provides a
positive slope output of 10 mV/°C over the full –40°C
to +150°C temperature range and a supply range
from 2.3 V to 5.5 V. The higher gain TMP236 sensor
provides a positive slope output of 19.5 mV/°C from
–10°C to +125°C and a supply range from 3.1 V to
5.5 V.
The 9-μA typical quiescent current and 800-μs typical
power-on time enable effective power-cycling
architectures to minimize power consumption for
battery-powered devices. A class-AB output driver
provides a strong 500-μA maximum output to drive
capacitive loads up to 1000 pF and is designed to
directly interface to analog-to-digital converter sample
and hold inputs. With excellent accuracy and a strong
linear output driver, the TMP23x analog output
temperature sensors are cost-effective alternatives to
passive thermistors.
