PRODUCT HIGHLIGHTS

1. Low Power, Single Supply Operation

GENERAL DESCRIPTION

The AD7819 is a high speed, microprocessor-compatible, 8-bit

analog-to-digital converter with a maximum throughput of

200 kSPS. The converter operates off a single 2.7 V to 5.5 V

supply and contains a 4.5 µs successive approximation A/D

converter, track/hold circuitry, on-chip clock oscillator and 8-bit

wide parallel interface. The parallel interface is designed to

allow easy interfacing to microprocessors and DSPs. Using only

address decoding logic the AD7819 is easily mapped into the

microprocessor address space.

The AD7819 operates from a single 2.7 V to 5.5 V supply

and typically consumes only 10.5 mW of power. The power

dissipation can be significantly reduced at lower through-

put rates by using the automatic power-down mode.

2. Automatic Power-Down

The automatic power-down mode, whereby the AD7819

goes into power-down mode at the end of a conversion and

powers up before the next conversion, means the AD7819

is ideal for battery powered applications; e.g., 57.75 µW

@ 1 kSPS. (See Power vs. Throughput Rate section.)

When used in its power-down mode, the AD7819 automatically

powers down at the end of a conversion and powers up at the

start of a new conversion. This feature significantly reduces the

power consumption of the part at lower throughput rates. The

AD7819 can also operate in a high speed mode where the part is

not powered down between conversions. In this mode of opera-

tion the part is capable of providing 200 kSPS throughput.

3. Parallel Interface

An easy to use 8-bit wide parallel interface allows interfacing

to most popular microprocessors and DSPs with minimal

external circuitry.

4. Dynamic Specifications for DSP Users

In addition to the traditional ADC specifications, the AD7819

is specified for ac parameters, including signal-to-noise ratio

and distortion.

The part is available in a small, 16-lead 0.3" wide, plastic dual-

in-line package (DIP); in a 16-lead, 0.15" wide, narrow body

small outline IC (SOIC) and in a 16-lead, narrow body, thin

shrink small outline package (TSSOP).
