MX7841 Octal, 14-Bit Voltage-Output DAC With Parallel Interface

The MX7841 contains eight 14-bit, voltage-output digital-to-analog converters (DACs). On-chip precision output Amplifiers provide the voltage outputs. The device operates from 15V supplies. Its bipolar output voltage swing ranges from (VSS + 2.5V) to (VDD - 2.5V) and is achieved with no external components. The MX7841 has three pairs of differential reference inputs; two of these pairs are connected to two DACs each, and a third pair is connected to four DACs The references are independently controlled, providing different full-scale output voltages to the respective DACs
The MX7841 features double-buffered Interface Logic with a 14-bit parallel data bus. Each DAC has an input latch and a DAC latch. Data in the DAC latch sets the output voltage. The eight input Latches are addressed with three address lines. Data is loaded to the input latch with a single write instruction. An asynchronous load input (active-low LDAC) transfers data from the input latch to the DAC latch. The active-low LDAC input controls all DACs; therefore, all DACs CAN be updated simultaneously by asserting active-low LDAC.
An asynchronous active-low CLR input sets the output of all eight DACs to the respective DUTGND input of the op amp Note that CLR-bar is a CMOS input, which is powered by VDD. All other Logic inputs are TTL/CMOS compatible. The MX7841 is pin-for-pin compatible with AD7841.
