Product Summary
The AD7839AS is an Octal 13-Bit, Parallel Input, Voltage-Output DAC. It contains eight 13-bit DACs on one monolithic chip. The device has output voltages with a full-scale range of ±10 V from reference voltages of ±5V. The AD7839AS accepts 13-bit parallel loaded data from the external bus into one of the input registers under the control of the WR, CS and DAC channel address pins, A0–A2. The AD7839AS DAC outputs are updated on reception of new data into the DAC registers. All the outputs may be updated simultaneously by taking the LDAC input low. Each DAC output is buffered with a gain-of-two amplifier into which an external DAC offset voltage can be inserted via the DUTGNDx pins. The AD7839AS is available in a 44-lead MQFP package. The applications of it include Automatic Test Equipment, Process Control, General Purpose Instrumentation.
