AD7417 (sensor)
Added by ALMICO on 01 nov 2002
The AD7416, AD7417 and AD7418 are 10-bit, 4-channel and single-channel A/D converters with an on-chip temperature sensor that can operate from a single 2.7 V to 5.5 V power supply. The devices contain a 15 us successive-approximation converter, a 5-channel multiplexer, a temperature sensor, a clock oscillator, a track-and-hold, and a reference (2.5 V). The AD7416 is a temperature-monitoring-only device in an 8-lead package. 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 (+-1C @ 25C). 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. A Configuration Register allows programming of the sense of the OTI output (active high or active low) and its Operating Mode (comparator or interrupt). A programmable fault queue counter allows the number of out of limit measurements that must occur before triggering the OTI output to be set to prevent spurious triggering of the OTI output in noisy environments. An I2C compatible serial interface allows the AD7416/AD7417/ AD7418 registers to be written to and read back. The three LSBs of the AD7416/AD7417's serial bus address can be selected, which allows up to eight AD7416/AD7417s to be connected to a single bus. The AD7417 is available in a narrow body, 0.15", 16-lead, small outline IC (SOIC) and in a 16-lead, thin shrink, small outline package (TSSOP). The AD7416 and AD7418 are available in 8-lead SOIC and MSOP packages.
