GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

1. Low Power, Single Supply Operation

The AD7813 is a high speed, microprocessor-compatible,

8-/10-bit analog-to-digital converter with a maximum through-

put of 400 kSPS. The converter operates off a single +2.7 V to

+5.5 V supply and contains a 2.3 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. The 10-bit

conversion result is read by carrying out two 8-bit read opera-

tions. The first read operation accesses the 8 MSBs of the ADC

conversion result and the second read accesses the 2 LSBs.

Using only address decoding logic the AD7813 is easily mapped

into the microprocessor address space.

The AD7813 operates from a single +2.7 V to +5.5 V sup-

ply and typically consumes only 10.5 mW of power. The

power dissipation can be significantly reduced at lower

throughput rates by using the automatic power-down mode.

2. Automatic Power-Down

The automatic power-down mode, whereby the AD7813

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

powers up before the next conversion, means the AD7813

is ideal for battery powered applications; e.g., 34.6 µW

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

3. Parallel Interface

When used in its power-down mode, the AD7813 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

AD7813 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 400 kSPS throughput.

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 AD7813

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

and distortion.

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

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

small outline IC (SOIC) and in a 16-pin thin shrink small out-

line package (TSSOP).
