BiMOS II allows the fabrication of low power CMOS logic functions on the same chip as high precision bipolar linear cir- cuitry. The AD569 chip includes two resistor strings, selector switches decoding logic, buffer amplifiers, and double-buffered input latches. PRODUCT HIGHLIGHTS 1. Monotonicity to 16 bits is insured by the AD569s voltage- The AD569s voltage-segmented architecture insures 16-bit segmented architecture. monotonicity over time and temperature. Integral nonlinearity is maintained at 0.01%, while differential nonlinearity is 2. The output range is ratiometric to an external reference or ac 0.0004%. The on-chip, high-speed buffer amplifiers provide a signal. Gain error and gain drift of the AD569 are negligible. voltage output settling time of 3 s to within 0.001% for a 3. The AD569s versatile data input structure allows loading full-scale step. from 8- and 16-bit buses. The reference input voltage which determines the output range 4. The on-chip output buffer amplifier can supply 5 V into a can be either unipolar or bipolar. Nominal reference range is 1 k load, and can drive capacitive loads of up to 1000 pF. 5 V and separate reference force and sense connections are 5. Kelvin connections to the reference inputs preserve the gain provided for high accuracy applications. The AD569 can oper- and offset accuracy of the transfer function in the presence of ate with an ac reference in multiplying applications. wiring resistances and ground currents. Data may be loaded into the AD569s input latches from 8- and 6. The AD569 is available in versions compliant with MIL-STD- 16-bit buses. The double-buffered structure simplifies 8-bit bus 883.

Four TTL/LSTTL/5 V specifications. CMOS-compatible signals control the latches: CS, LBE, HBE, and LDAC The AD569 is available in five grades: J and K versions are specified from 0C to +70C and are packaged in a 28-pin plas- tic DIP and 28-pin PLCC package AD and BD versions are specified from 25C to +85C and are packaged in a 28-pin ceramic DIP. The SD version, also in a 28-pin ceramic DIP, is specified from 55C to +125C. REV. A Information furnished by Analog Devices is believed to be accurate and reliable.
