GENERAL DESCRIPTION  
The AD7417 and AD7418 are 10-bit, 4-channel and single-channel  
ADCs 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 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 AD7416 is a temperature-monitoring only  
device in an 8-lead package.

The temperature sensor on the parts can be accessed via multip-  
lexer 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 @ 25°C).  
On-chip registers can be programmed with high and low tempera-  
ture 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.
