The AD669 is a complete voltage output 16-bit DAC with converter with an on-board reference and output amplifier. It is voltage reference and digital latches on a single IC chip. manufactured on Analog Devices BiMOS II process. This pro- 2. The internal buried Zener reference is laser trimmed to cess allows the fabrication of low power CMOS logic functions 10.000 volts with a 0.2% maximum error. The reference on the same chip as high precision bipolar linear circuitry. The voltage is also available for external applications. AD669 chip includes current switches, decoding logic, an output 3. The AD669 is both dc and ac specified. DC specs include amplifier, a buried Zener reference and double-buffered latches. 1 LSB INL error and 1 LSB DNL error. AC specs include The AD669s architecture insures 15-bit monotonicity over 0.009% THD+ N and 83 dB SNR. The ac specifications temperature. Integral nonlinearity is maintained at 0.003%, make the AD669 suitable for signal generation applications. while differential nonlinearity is 0.003% max. The on-chip 4. The double-buffered latches on the AD669 eliminate data output amplifier provides a voltage output settling time of 10 s skew errors while allowing simultaneous updating of DACs in to within 1/2 LSB for a full-scale step. multi-DAC systems. Data is loaded into the AD669 in a parallel 16-bit format. The 5. The output range is a pin-programmable unipolar 0 V to double-buffered latch structure eliminates data skew errors and +10 V or bipolar 10 V to +10 V output. No external compo- provides for simultaneous updating of DACs in a multi-DAC nents are necessary to set the desired output range. system. Three TTL/LSTTL/5 V CMOS compatible signals con- trol the latches: CS, L1 and LDAC. 6. The AD669 is available in versions compliant with MIL- STD-883. Refer to the Analog Devices Military Products The output range of the AD669 is pin programmable and can Databook or current AD669/883B data sheet for detailed be set to provide a unipolar output range of 0 V to +10 V or a specifications. bipolar output range of 10 V to +10 V. The AD669 is available in seven grades: AN and BN versions are specified from 40C to +85C and are packaged in a 28-pin plastic DIP. The AR and BR versions are specified for 40C to +85C operation and are packaged in a 28-pin SOIC. The SQ version is specified from 55C to +125C and is packaged in a hermetic 28-pin cerdip package. The AD669 is also available compliant to MIL-STD-883. Refer to the AD669/883B data sheet for specifications and test conditions. DACPORT is a registered trademark of Analog Devices, Inc. REV.
