GENERAL DESCRIPTION
The AD7818 and AD7817 are 10-bit, single- and 4-channel A/D converters with
on-chip temperature sensor that can operate from a single 2.7 V to 5.5 V power
supply. Each part contains a 9 µs successive-approximation converter based
around a capacitor DAC, an on-chip temperature sensor with an accuracy of
±2°C, an on-chip clock oscillator, inherent track-and hold functionality and
an on-chip reference (2.5 V). The AD7816 is a temperature monitoring only
device in a SOIC/µSOIC package.
The on-chip temperature sensor of the AD7817 and AD7818 can be accessed via
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 with a resolution of ±0.25°C. See Measuring Temperature
section of the data sheet.
The AD7816, AD7817 and AD7818 have a flexible serial interface that allows
easy interfacing to most microcontrollers. The interface is compatible with
the Intel 8051, Motorola SPI™ and QSPI™ protocols and National Semiconductors
MICROWIRE™ protocol. For more information refer to the Serial Interface
section of this data sheet.
The AD7817 is available in a narrow body 0.15" 16-lead Small Outline IC
(SOIC), in a 16-lead, Thin Shrink Small Outline Package (TSSOP), while the
AD7816/AD7818 come in an 8-lead Small Outline IC (SOIC) and an 8-lead
microsmall Outline IC (µSOIC).
