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.
