MAX5270, MAX5270A, MAX5270B Octal, 13-Bit Voltage-Output DAC With Parallel Interface

The MAX5270 contains eight 13-bit, voltage-output digital-to-analog converters (DACs). On-chip precision output Amplifiers provide the voltage outputs. The device operates from +12V/-12V supplies. Its output voltage swing ranges from 0V to -8.192V and is achieved with no external components. The MAX5270 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 MAX5270 operates within the following voltage ranges: VDD = +11.4V to +12.6V, VSS = -11.4V to -12.6V, and VCC = +4.75V to +5.25V.
The MAX5270 features double-buffered Interface Logic with a 13-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 LD) transfers data from the input latch to the DAC latch. The active-low LD input controls all DACs; therefore, all DACs CAN be updated simultaneously by asserting the LD-bar pin.
An asynchronous active-low CLR input sets the output of all eight DACs to the respective DUTGND input of the op amp Note that active-low CLR is a CMOS input, which is powered by VDD. All other Logic inputs are TTL/CMOS compatible. The "A" grade of the MAX5270 has a maximum INL of 2LSBs, while the "B" grade has a maximum INL of 4LSBs. Both grades are available in 44-pin MQFP packages.
