Exar Corporation MP7645B
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. These control inputs are level triggered; tying these inputs low makes the input latch transparent allowing direct unbuffered operation of the DAC.| Part No. | MP7645B |
