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.  
– DigitalFeedthroughTheMP7645Bhas5to8timeslessdig-  
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-
