TMP103BYFFR

低功耗数字温度传感器，具有双线接口的WCSP Low-Power, Digital Temperature Sensor with Two-Wire Interface in WCSP

Description

The TMP103 is a digital output temperature sensor in a four-ball wafer chip-scale package WCSP. The TMP103 is capable of reading temperatures to a resolution of 1°C.

The TMP103 features a two-wire interface that is compatible with both I2C and SMBus interfaces. 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 TMP103 on the bus. Up to eight TMP103s can be tied together in parallel and easily read by the host. The TMP103 is especially suitable for space-constrained, power sensitive applications with multiple temperature measurement zones that must be monitored.

The TMP103 is specified for operation over a temperature range of –40°C to 125°C.
