Product Summary

The AD7416AR is a 10-bit, 4-channel and singlechannel ADC with an on-chip temperature sensor that can operate from a single 2.7 V to 5.5 V power supply. The AD7416AR contains a 15 μs successive approximation converter, a 5-channel multiplexer, a temperature sensor, a clock oscillator, a track-and-hold, and a reference (2.5 V). The AD7416AR is a temperature-monitoring only device in an 8-lead package. The AD7416AR 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℃ @ 25℃). On-chip registers can be programmed with high and low temperature limits, and an open-drain overtemperature indicator (OTI) output is provided, which becomes active when a programmed limit is exceeded.
