The AD7886 is fabricated in Analog Devices’ Linear Com-

patible CMOS process, a mixed technology process that

combines precision bipolar circuits with low power CMOS

logic.

GENERAL DESCRIPTION

The AD7886 is a 12-bit ADC with a sample-and-hold amplifier

offering high speed performance combined with low power dissi-

pation. The AD7886 is a triple pass flash ADC that uses 15

comparators in a 4-bit flash technique to achieve 12-bit accuracy

in 1 µs/750 ns conversion time. An on-chip clock oscillator pro-

vides the appropriate timing for each of the three conversion

stages, eliminating the need for any external clocks. Acquisition

time of the sample-and-hold amplifier gives a resulting through-

put rate of 750 kHz/1 MHz.*

The AD7886 is available in both a 28-pin DIP and a 28-pin

leaded chip carrier.

PRODUCT HIGHLIGHTS

1. Fast 1.33 µs/1 µs Throughput Time.

Fast throughput time makes the AD7886 suitable for a

wide range of data acquisition applications.

The AD7886 operates from ±5 V power supplies. Pin-strappable

inputs offer a choice of three analog input ranges: 0 V to 5 V,

0 V to 10 V or ±5 V.

2. Dynamic Specifications for DSP Users.

The AD7886 is specified for ac parameters, including

signal-to-noise ratio, harmonic distortion and inter-

modulation distortion. Key digital timing parameters are

also tested and guaranteed over the full operating tem-

perature range.

In addition to the traditional dc accuracy specifications such as

linearity, offset and full-scale errors, the AD7886 is also speci-

fied for dynamic performance parameters, including harmonic

distortion and signal-to-noise ratio.

3. Fast Microprocessor Interface.

The AD7886 has a high speed digital interface with three-state

data outputs. Conversion control is provided by a CONVST in-

put. Data access is controlled by CS and RD inputs, standard

microprocessor signals. The data access time of less than 57 ns

means that the AD7886 can interface directly to most modern

microprocessors, including DSP processors.

Standard control signals, CS and RD, and fast bus ac-

cess times make the AD7886 easy to interface to micro-

processors.

4. Low Power.

LC²MOS fabrication process gives low power dissipa-

tion of 250 mW.
