PRODUCT DESCRIPTION

AD571

The AD571 is an 10-bit successive approximation A/D con-

verter consisting of a DAC, voltage reference, clock, compara-

tor, successive approximation register and output buffers—all

fabricated on a single chip. No external components are re-

quired to perform a full accuracy 10-bit conversion in 40 µs.

DATA READY

PRODUCT HIGHLIGHTS

1. The AD571 is a complete 10-bit A/D converter. No external

components are required to perform a conversion. Full-scale

calibration accuracy of ±0.3% is achieved without external

trims.

Operating on supplies of +5 V to +15 V and –15 V, the

AD571 will accepts analog inputs of 0 V to +10 V unipolar of

±5 V bipolar, externally selectable. When the BLANK and

CONVERT input is driven low, the three-state outputs will be

open and a conversion will commence. Upon completion of the

conversion, the DATA READY line goes low and the data ap-

pears at the output. Pulling the BLANK and CONVERT input

high blanks the outputs and readies the device for the next con-

version. The AD571 executes a true 10-bit conversion with no

missing codes in 40 µs maximum.

2. The AD571 is a single chip device employing the most ad-

vanced IC processing techniques. Thus, the user has at his

disposal a truly precision component with the reliability and

low cost inherent in monolithic construction,

3. The AD571 accepts either unipolar (0 V to +10 V) or bipolar

(–5 V to +5 V) analog inputs by grounding or opening a

single pin.

The AD571 is available in two version for the 0°C to +70°C

temperature range, the AD571J and K. The AD571S guarantees

10-bit accuracy and no missing codes from –55°C to +125°C.

4. The device offers true 10-bit accuracy and exhibits no miss-

ing codes over its entire operating temperature range.

*Covered by Patent Nos. 3,940,760; 4,213,806; 4,136,349.

5. Operation is guaranteed with –15 V and +5 V or +15 V sup-

plies. The device will also operate with a –12 V supply.
