The TMP103AYFFT is a digital output temperature sensor in a four-ball wafer chip-scale package. The TMP103AYFFT is capable of reading temperatures to a resolution of 1°C. This IC features two-wire interface that is compatible with both I2C and SMBus interfaces. In addition, the interface supports multiple device access commands that allow the master to communicate with multiple devices on the bus simultaneously. the TMP103AYFFT is ideal for space-constrained, power-sensitive applications with multiple temperature measurement zones that must be monitored.
