16/12-Bit Voltage Output DAC's


Maxim and Digi-Key Introduce MAX5134 - MAX5137 Pin/Software Programmable DACs

The MAX5134–MAX5137 is a family of pin compatible and software compatible 16-bit and 12-bit DACs. The MAX5134/MAX5135 are low-power, quad 16/12-bit, buffered voltage output, high-linearity DACs. The MAX5136/MAX5137 are low-power, dual 16/12-bit, buffered voltage-output, high-linearity DACs. They use a precision internal reference or a precision external reference for rail-to-rail operation. The MAX5134–MAX5137 accept a wide +2.7V to +5.25V supply-voltage range to accommodate most low power and low voltage applications. These devices accept 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 updates. The serial interface features an active-low READY output for easy daisy-chaining of several MAX5134–MAX5137 devices and/or other compatible devices. The MAX5134–MAX5137 include a hardware input to reset the DAC outputs to zero or midscale upon power-up or reset, providing additional safety for applications that drive valves or other transducers that need to be off during power-up.
