3 Description

The TMP23x devices are a family of precision CMOS

integrated-circuit linear analog temperature sensors

with an output voltage proportional to temperature,

making

the

series

suitable

for

multiple

analog

temperature sensing applications. These temperature

sensors

are

more

accurate

than

similar

pin-

compatible devices on the market, featuring accuracy

from 0°C to +70°C of ±1°C and ±2°C. The increased

accuracy makes this series suitable 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 2.3 V to 5.5 V supply range. The higher gain

TMP236 sensor provides a positive slope output of

19.5 mV/°C from –10°C to +150°C and a 3.1 V to 5.5

V supply range.

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 well-suited 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 excellent, cost-effective

alternatives to passive thermistors.
