The AD569 is a monolithic 16-bit digital-to-analog converter (DAC) manufactured in Analog Devices' BiMOS II process. BiMOS II allows the fabrication of low power CMOS logic functions on the same chip as high precision bipolar linear circuitry. The AD569 chip includes two resistor strings, selector switches decoding logic, buffer amplifiers, and double-buffered input latches.The AD569's voltage-segmented architecture insures 16-bit monotonicity over time and temperature. Integral nonlinearity is maintained at ±0.01%, while differential nonlinearity is ±0.0004%. The on-chip, high-speed buffer amplifiers provide a voltage output settling time of 3 µs to within ±0.001% for a full-scale step.The reference input voltage which determines the output range can be either unipolar or bipolar. Nominal reference range is ±5 V and separate reference force and sense connections are provided for high accuracy applications. The AD569 can operate with an ac reference in multiplying applications.Data may be loaded into the AD569's input latches from 8- and 16-bit buses. The double-buffered structure simplifies 8-bit bus interfacing and allows multiple DACs to be loaded asynchronously and updated simultaneously. Four TTL/LSTTL/5 V CMOS-compatible signals control the latches:CS,LBE,HBE, andLDAC.The AD569 is available in five grades: J and K versions are specified from 0°C to +70°C and are packaged in a 28-pin plastic DIP and 28-pin PLCC package; AD and BD versions are specified from −25°C to +85°C and are packaged in a 28-pin ceramic DIP. The SD version, also in a 28-pin ceramic DIP, is specified from −55°C to +125°C.

The AD570 is an 8-bit successive approximation A/D converter consisting of a DAC, voltage reference, clock, comparator, successive approximation register and output buffers-all fabricated on a single chip. No external components are required to perform a full accuracy 8-bit conversion in 25 µs.The AD570 incorporates the most advanced integrated circuit design and processing technology available today. I2L (integrated injection logic) processing in the fabrication of the SAR function along with laser trimming of the high stability SiCr thin-film resistor ladder network at the wafer stage (LWT) and a temperature compensated, subsurface Zener reference insures full 8-bit accuracy at low cost.Operating on supplies of +5 V and -15 V, the AD570 accepts analog inputs of 0 V to +10 V unipolar of ±5 V bipolar, externally selectable. As the BLANK andCONVERTinput is driven low, the three-state outputs go into the high impedance state and a conversion commences. Upon completion of the conversion, theDATAREADYline goes low and the data appears at the output. Pulling the BLANK andCONVERTinput high three states the outputs and readies the device for the next conversion. The AD570 executes a true 8-bit conversion with no missing codes in approximately 25 µs.The AD570 is available in two versions; the AD570J is specified for the 0°C to +70°C temperature range, the AD570S for -55°C to +125°C. Both guarantee full 8-bit accuracy and no missing codes over their respective temperature ranges.PRODUCT HIGHLIGHTSThe AD570 is a complete 8-bit A/D converter. No external components are required to perform a conversion. Full-scale calibration accuracy of ± 0.8% (2 LSB of 8 bits) is achieved without external trims.The AD570 is a single chip device employing the most advanced IC processing techniques. Thus, the user has at his disposal a truly precision component with the reliability and low cost inherent in monolithic construction.The AD570 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 device offers true 8-bit accuracy and exhibits no missing codes over its entire operating temperature range.Operation is guaranteed with –15 V and +5 V supplies. The device will also operate with a –12 V supply.The AD570S is also available processed to MIL-STD-883C, Class B. The military data sheet for the AD570SD/883B is included in the Analog Devices Military Products Databook.
