MAX5270 - Maxim

MAX5270 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 o.

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.
