MAX5134, MAX5135, MAX5136, MAX5137 概述

The MAX5134 is a low-power, quad 16-bit, buffered voltage- output, high-linearity digital-to-analog converter (DAC). It uses a precision internal reference or a precision external reference for rail-to-rail operation. The MAX5134 accepts a wide +2.7V to +5.25V supply-voltage range to accommodate most low-power and low-voltage applications. The device accepts a 3-wire SPI™-/QSPI™-/MICROWIRE™-/DSP-compatible serial interface to save board space and reduce the complexity of optically isolated and transformer-isolated applications. The digital interface’s double-buffered hardware and software active-low LDAC provide simultaneous output update. The serial interface features an active-low READY output for easy daisy-chaining of several MAX5134 devices and/or other compatible devices. The MAX5134 includes a hardware input to power-up or reset the DAC outputs to zero or midscale, providing additional safety for applications that drive valves or other transducers that need to be off during power-up. The high linearity of the DACs makes these devices ideal for precision control and instrumentation applications. The MAX5134 is available in an ultra-small (4mm x 4mm), 24-pin TQFN package and is specified over the -40°C to +105°C extended industrial temperature range.
