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 and ±1°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.
