T he DAC8248 is a dual 12-bit, double-buffered, CMOS digital-
to-analog converter. It has an 8-bit wide input data port that inter-
faces directly with 8-bit microprocessors. It loads a 12-bit word in
two bytes using a single control; it can accept either a least signifi-
cant byte or most significant byte first. For designs with a 12-bit or
16-bit wide data path, choose the DAC8222 or DAC8221.
T he DAC8248’s double-buffered digital inputs allow both
DAC’s analog output to be updated simultaneously. T his is par-
ticularly useful in multiple DAC systems where a common
LDAC
signal updates all DACs at the same time. A single
RESET
pin resets both outputs to zero.
T he DAC8248’s monolithic construction offers excellent DAC-
to-DAC matching and tracking over the full operating tempera-
ture range. T he DAC consists of two thin-film R-2R resistor
ladder networks, two 12-bit, two 8-bit, and two 4-bit data regis-
ters, and control logic circuitry. Separate reference input and
feedback resistors are provided for each DAC. T he DAC8248
