The AD7884 / AD7885 is a 16-bit monolithic analog-to-digital converter with internal sample-and-hold and a conversion time of 5.3 µs. 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 2s complement code.
The AD7884 / AD7885 has its own internal oscillator which controls conversion. It runs from ±5 V supplies and needs a VREF+ of +3 V.
The AD7884 is available in a 40-pin plastic DIP package and in a 44-pin PLCC package.
The AD7885 is available in a 28-pin plastic DIP package and the AD7885A is available in a 44-pin PLCC package.
