GENERAL DESCRIPTIONS

The MP7680 and the integrate four 12-bit four-quadrant-

multiplying DACs with independent reference inputs and

excellent matching characteristics. The MP7680 grades

offer 1/2, 1 and 2 LSB of relative accuracy. The superior

offers a low 2 LSB of gain error.

Each DAC has double-buffering (an 8 and 4-bit latch and

a 12-bit latch) between the data bus (DB11 - DB0) and the

DAC. The internal 4-bit mux allows the use of 8 or 16-bit

buses. The flexible latch control logic allows to update

one or more DACs simultaneously.
