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 at 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.
