•

Multiple Device Access (MDA):

a four-ball wafer chip-scale package (WCSP). The

– Global Read/Write Operations

TMP104 is capable of reading temperatures to a

resolution of 1

°C.

•

Resolution: 8 Bits

The TMP104 features a SMAART wire interface that

•

Accuracy:

±0.5°C Typ (–10°C to +100°C)

supports daisy-chain configurations. In addition, the

interface supports multiple device access (MDA)

•

Low Quiescent Current:

commands that allow the master to communicate with

multiple

devices

on

the

bus

simultaneously,

– 1 μA Shutdown

eliminating the need to send individual commands to

each TMP104 on the bus.

•

Supply Range: 1.4 V to 3.6 V

•

Digital Output

Up to 16 TMP104s can be tied together in parallel

and easily read by the host. The TMP104 is
