DescriptionThe MAX5270AEMH contains eight 13-bit, voltage-output digi-tal-to-analog converters (DACs). On-chip precision out-put amplifiers provide the voltage outputs. The deviceoperates from +12V/ 12V supplies. Its output voltageswing ranges from 0V to +8.192V and is achieved with no external components. The MAX5270AEMH has three pairs of differential reference inputs; two of these pairs are connected to two DACs each, and a third pair is con-nected to four DACs. The references are independently controlled, providing different full-scale output voltages to the respective DACs. The MAX5270AEMH 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 MAX5270AEMH 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 (LD ) transfers data from the input latch to the DAC latch. The LD input controls all DACs; therefore, all DACs can be updated simultaneously by asserting the LD pin.An asynchronous CLR input sets the output of all eight DACs to the respective DUTGND input of the op amp.Note that CLR is a CMOS input, which is powered by VDD. All other logic inputs are TTL/CMOS compatible.The "A" grade of the MAX5270AEMH 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.
