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