D/A Converter with Memory
DAC8408
FEATURES A common 8-bit TTL/CMOS compatible input port is used to
Four DACs in a 28 Pin, 0.6 Inch Wide DIP or 28-Pin JEDEC load data into any of the four DAC data-latches. Control lines
Plastic Chip Carrier DS1, DS2, and A/B determine which DAC will accept data.
61/4 LSB Endpoint Linearity Data loading is similar to that of a RAMs write cycle. Data can
Guaranteed Monotonic be read back onto the same data bus with control line R/W. The
