AD669ANZ

AD669 is a monolithic 16-bit DACPORT. 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. This device chip includes current switches, decoding logic, an output amplifier, a buried Zener reference and double-buffered latches. Data is loaded into the device 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.
