TC74A2-3.3VAT is a serially accessible digital temperature sensor particularly suited for low cost and small form-factor applications. Temperature data is converted from the on-board thermal sensing element and made available as an 8-bit digital word.Communication with the TC74A2-3.3VAT is accomplished via a simple 2-wire SMBus/I2C™-compatible serial port.This bus also can be used to implement multi-drop/multi-zone monitoring.The SHDN bit in the CONFIG register can be used to activate the low-power Standby mode.Temperature resolution is 1°C.Conversion rate is a nominal 8 samples/sec.Power consumption in only 200 µA (5 µA Standby).Small size, low installed cost and ease of use make the TC74A2-3.3VAT an ideal choice for implementing thermal management in a variety of systems.
