LTC1392 - Micropower Temperature, Power Supply and Differential Voltage Monitor - Linear Technology（凌力尔特）

功能描述
The LTC?1392 is a micropower data acquisition system designed to measure temperature, on-chip supply voltage and a differential voltage. The differential inputs feature rail-to-rail common mode input voltage range. The LTC1392 contains a temperature sensor, a 10-bit A/D converter with sample-and-hold, a high accuracy bandgap reference and a 3-wire half-duplex serial interface.The LTC1392 can be programmed to measure ambient temperature, power supply voltage and an external voltage at the differential input pins, that can also be used for current measurement using an external sense resistor. When measuring temperature, the output code of the A/D converter is linearly proportional to the temperature in °C. Production trimming achieves ?2°C initial accuracy at room temperature and ?4°C over the full ?40°C to 85°C temperature range.The on-chip serial port allows efficient data transfer to a wide range of MPUs over three or four wires. This, coupled with low power consumption, makes remote location sensing possible and facilitates transmitting data through isolation barriers.
