AD7416ARZ

The AD7416ARZ is a 10-bit Digital Temperature Sensor and Four 1-channel ADC with an on-chip temperature sensor that can operate from a single 2.7 to 5.5V power supply. The devices contain a 15µs successive approximation converter, a 5-channel multiplexer, a temperature sensor, a clock oscillator, a track-and-hold and a reference (2.5V). The temperature sensor on the parts can be accessed via multiplexer Channel 0. When Channel 0 is selected and a conversion is initiated, the resulting ADC code at the end of the conversion gives a measurement of the ambient temperature (±1°C at 25°C). On-chip registers can be programmed with high and low temperature limits and an open-drain over-temperature indicator (OTI) output is provided, which becomes active when a programmed limit is exceeded. A configuration register allows programming of the sense of the OTI output (active high or active low) and its operating mode (comparator or interrupt).
