Temp sensors offer accuracy of ±1°C max

Temp sensors offer accuracy of ±1°C max

Housed in an 8-lead SOT23 package, the single remote-channel TMP421 and dual remote-channel TMP422 temperature sensors feature n-factor and series resistance correction. Both provide a remote sensor accuracy of ±1°C max and feature a local sensor with ±1.5°C accuracy.

The sensors operate on a standard I2 C/SMBus compatible, two-wire interface over a temperature range of 40° to 125°C, with a remote temperature range of up to 150°C. For maximum power savings, the device circuitry (other than the serial interface) can be shut down, thereby reducing current consumption to typically less than 3 μA. (Ea/1,000: TMP421, $1.25; TMP422, $1.65—available now.)
