General Description

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.
