The AD7884/AD7885 is a 16-bit monolithic analog-to-digital converter with internal sample-and-hold and a conversion time of 5.3 t,s. The maximum throughput rate is 166 kSPS. It uses a two-pass flash architecture to achieve this speed. Two input ranges are available: +- 5 V and +-3 V. Conversion is initiated by the CONVST signal. The result can be read into a microprocessor using the CS and RD inputs on the device. The AD7884 has a 16-bit parallel reading structure while the AD7885 has a byte reading structure. The conversion result is in twos complement code. The AD7884/AD7885 has its own internal oscillator that controls conversion. It runs from +-5 V supplies and needs a V REF+ of 3 V. The AD7884 is available in a 40-lead CERDIP package and a 44-lead PL CC package. The AD7885 is available in a 28-lead CERDIP package and theAD7885A is available in a 44-lead PL CC package.
