AD573

PRODUCT DESCRIPTION

The AD573 is a complete 10-bit successive approximation

analog-to-digital converter consisting of a DAC, voltage refer-

ence, clock, comparator, successive approximation register

(SAR) and three state output buffers—all fabricated on a single

chip. No external components are required to perform a full

accuracy 10-bit conversion in 20 µs.

PRODUCT HIGHLIGHTS

l. The AD573 is a complete 10-bit A/D converter. No external

components are required to perform a conversion.

2. The AD573 interfaces to many popular microprocessors

without external buffers or peripheral interface adapters. The

10 bits of output data can be read as a 10-bit word or as 8-

and 2-bit words.

The AD573 incorporates advanced integrated circuit design and

processing technologies. The successive approximation function

is implemented with I²L (integrated injection logic). Laser trim-

ming of the high stability SiCr thin-film resistor ladder network

insures high accuracy, which is maintained with a temperature

compensated subsurface Zener reference.

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

ing codes over its entire operating temperature range.

4. The AD573 adapts to either unipolar (0 V to +10 V) or

bipolar (–5 V to +5 V) analog inputs by simply grounding or

opening a single pin.

Operating on supplies of +5 V and –12 V to –15 V, the AD573

will accept analog inputs of 0 V to +10 V or –5 V to +5 V. The

trailing edge of a positive pulse on the CONVERT line initiates

the 20 µs conversion cycle. DATA READY indicates completion

of the conversion. HIGH BYTE ENABLE (HBE) and LOW

BYTE ENABLE (LBE) control the 8-bit and 2-bit three state

output buffers.

5. Performance is guaranteed with +5 V and –12 V or –15 V

supplies.

6. The AD573 is available in a version compliant with MIL-STD-

883. Refer to the Analog Devices Military Products Data-

book or current /883B data sheet for detailed specifications.

The AD573 is available in two versions for the 0°C to +70°C

temperature range, the AD573J and AD573K. The AD573S

guarantees ±1 LSB relative accuracy and no missing codes from

–55°C to +125°C.

Three package configurations are offered. All versions are offered

in a 20-pin hermetically sealed ceramic DIP. The AD573J and

AD573K are also available in a 20-pin plastic DIP or 20-pin

leaded chip carrier.
