perature. Monotonicity is guaranteed over the entire tem-

perature range including the industrial and military ranges.

The gain error specification of 2 ppm/°C over a 100°C tem-

perature range equals 0.8 LSB of error.

GENERAL DESCRIPTION

The MP7645B is an improved precision, monolithic 12-bit

CMOS 4-quadrant multiplying DAC with an on-board data latch.

The latch is loaded by a single 12-bit wide word. Data is loaded

into the input latch under the control of CS and WR inputs.

These control inputs are level triggered; tying these inputs low

makes the input latch transparent allowing direct unbuffered op-

eration of the DAC.

– DigitalFeedthrough–TheMP7645Bhas5to8timeslessdig-

ital feedthrough than similar buffered DACs.

– Low Sensitivity to Output Amplifier Offset – The additional

linearity error incurred by amplifier offset is reduced by a fac-

tor of at least 3 in the MP7645B over conventional DACs.

High latch-up resistance and high ESD protection make this a

rugged, reliable attenuator!

– Stability – The MP7645B incorporates a unique decoding

technique yielding excellent accuracy and stability over tem-
