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 µs 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- [ … ]
