MX7528, MX7628
CMOS, Dual, Buffered, 8-Bit Multiplying DAC
|
Status
Active: In Production.
Description
The MX7528/MX7628 contains two 8-bit multiplying digital-to-analog converters (DACs). Separate on-chip latches hold the input data for each DAC to allow easy interface to microprocessors. The data load operation is similar to a static RAM write cycle. Data is loaded using only active-low CS, active-low WR, and DAC Select (active-low DAC A /DAC B) inputs.
Each DAC has a separate reference input and internal feedback resistor which allow fully independent operation while maintaining excellent DAC-to-DAC matching. The MX7528 operates from a single +5 to +15V power supply whereas the MX7628 operates from +12V to +15V. The MX7528 has TTL compatible inputs at +5V supply only and the MX7628 has TTL compatible inputs from +12V to +15V supplies. The MX7528/MX7628 is supplied in 20-lead narrow DIP and Small Outline Packages.
