OCTAL, 13-BIT, -4V TO +9V VOLTAGE-OUTPUT DAC WITH PARALLEL INTERFACE
SUNNYVALE, CA—August 7, 2000—Maxim Integrated Products announces the MAX5839, a high-integration IC containing eight 13-bit digital-to-analog converters (DACs) with buffered outputs. The output voltages have a full-scale range of +4V to +9V from reference voltages of +2V to +4.5V. There are three separate differential reference inputs, allowing each group of DACs to have an independent output range. The output amplifiers remain stable, driving capacitive loads up to 10,000pF. In addition, output glitch can be as low as 30mV during major carry transitions. The MAX5839 also offers low 120nV per root-Hz output noise and 75µV DC crosstalk.
The MAX5839 accepts 13-bit parallel-loaded data from the external bus into one of the eight input registers under the control of the WR, CS, and DAC address pins, A0-A2. The DAC outputs are updated upon receipt of new data into the DAC registers. Each DAC output is buffered with a gain of two amplifiers into which an external DAC offset voltage can be inserted via the SYSGND pins. The MAX5839 is available in a space-saving 44-pin MQFP package. Prices start from $22.50 (1000-up, FOB USA).
