Description

The MAX5264 contains eight 14-bit, voltage-output digital-to-analog converters (DACs). On-chip precision output amplifiers provide the voltage outputs. The device operates from +14V/-9V supplies. Its bipolar output voltage swing ranges from +9V to -4V and is achieved with no external components. The MAX5264 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 MAX5264 operates within the following voltage ranges: VDD = +7V to +14V, VSS = -5V to -9V, and VCC = +4.75V to +5.25V. The MAX5264 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 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 active-low LD 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 MAX5264 has a maximum INL of ±4LSBs, while the "B" grade has a maximum INL of ±8LSBs. Both grades are available in 44-pin MQFP packages.
