Performing a function that you have previously done and consuming considerably less power is a goal for many system designers today. If the solution is crammed into even less space – so much the better. For temperature sensing that is the one-two punch that Texas Instruments delivers with its TMP103 digital temperature sensor.
The TMP103 draws a maximum of 1 µA while in shutdown mode and 3 µA while in active mode to extend battery life. Its active state power consumption is approximately half the power of the next closest competitor in shutdown state.
The two-wire IC is packaged in a four-ball wafer chip-scale package (WCSP) that measures only 0.76 mm x 0.76 mm. Capable of reading temperatures to a resolution of 1°C, the sensor’s two-wire interface is compatible with both I2C and SMBus interfaces and can support up to eight daisy-chained sensors.
