3 Description

The TMP104 device is a digital output temperature

sensor in a four-ball wafer chip-scale package

(WCSP). The TMP104 is capable of reading

temperatures to a resolution of 1°C.

The TMP104 features a SMAART wire™ interface

that supports daisy-chain configurations. In addition,

the interface supports multiple device access (MDA)

commands that allow the master to communicate with

multiple devices on the bus simultaneously,

eliminating the need to send individual commands to

each TMP104 on the bus.

Up to 16 TMP104s can be tied together in parallel

and easily read by the host. The TMP104 is

especially ideal for space-constrained, powersensitive

applications with multiple temperature

measurement zones that must be monitored.

The TMP104 is specified for operation over a

temperature range of –40°C to +125°C.
