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 temperature-

sensing 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 temperature-

sensing 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.
