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. 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 oper- ate 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 asynchro- nously and updated simultaneously. Four TTL/LSTTL/5 V 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 0 °C to +70°C and are packaged in a 28-pin plas- tic 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. One Technology Way, P.O. Box 9106, Norwood, MA 02062-9106, U.S.A. Tel: 617/329-4700 Fax: 617/326-8703 PRODUCT HIGHLIGHTS 1. Monotonicity to 16 bits is insured by the AD569’s voltage- segmented architecture. 2. The output range is ratiometric to an external reference or ac signal. Gain error and gain drift of the AD569 are negligible. 3. The AD569’s versatile data input structure allows loading from 8- and 16-bit buses. 4. The on-chip output buffer amplifier can supply ±5 V into a 1 k Ω load, and can drive capacitive loads of up to 1000 pF. 5. Kelvin connections to the reference inputs preserve the gain and offset accuracy of the transfer function in the presence of wiring resistances and ground currents. 6. The AD569 is available in versions compliant with MIL-STD- 883. Refer to the Analog Devices Military Products Data- book or current AD569/883B data sheet for detailed specifications. |
