GENERAL DESCRIPT ION
T he AD7417 and AD7418 are 10-Bit, single and four-
channel A/D Converters with an On-Chip T emperature
Sensor that can operate from a single 2.7V to 5.5V power
supply. T he devices contain a 15μs successive-
approximation converter, a 5-Channel Multiplexer, a
T emperature Sensor, a Clock Oscillator, a T rack/Hold
and a Reference (2.5V). T he AD7416 is a temperature
monitoring only device in an 8-pin package.
T he T emperature Sensor on the parts can be accessed via
multiplexer channel 0. When channel 0 is selected and a
conversion initiated, the resulting ADC code gives a
measurement of the ambient temperature (±1°C @ 25°C).
On-chip registers can be programmed with high and low
temperature limits, and an open-drain Over T emperature
Indicator output (OT I) is provided, which becomes active
when a programmed limit is exceeded.
An I

C-compatible serial interface allows the AD7416/17/
18 registers to be written to and read back. T he three
LSBs of the AD7416/17’s serial bus address can be
selected, which allows up to 8 AD7416/17s to be
connected to a single bus.
T he AD7417 is available in a Narrow Body 0.15'' 16 Lead
mall Outline IC (SOIC) and in a 16 Lead, T hin Shrink
Small Outline Package (T SSOP). T he AD7416 and
AD7418 are available in SOIC and 8-lead MicroSmall
Outline (uSOIC ).

1. On-Chip T emperature Sensor for accurate
measurement of the ambient temperature (±1°C @
25C, ±2°C over temperature). T he measurable
temperature range is -55°C to +125°C.
2. Space saving 10-Bit A/D solution with four voltage
input channels, a T emperature Sensor, Reference and
C lock Oscillator.
3. Automatic Power Down and Programmable Shutdown
features enable superior power performance.
