The MAX5171/MAX5173 low-power, serial, voltage-output, 14-bit digital-to-analog converters (DACs) feature a precision output amplifier in a space-saving 16-pin QSOP package. The MAX5171 operates from a +5V single supply, and the MAX5173 operates from a +3V single supply. The output amplifier's inverting input is available to allow specific gain configurations, remote sensing, and high output current capability. This makes the MAX5171/ MAX5173 ideal for a wide range of applications, including industrial process control. Both devices draw only 260µA of supply current, which reduces to 1µA in shutdown mode. In addition, the programmable power-up reset feature allows for a user-selectable output voltage of either 0 or midscale.

The 3-wire serial interface is compatible with SPI™, QSPI™, and MICROWIRE™ standards. An input register followed by a DAC register provides a double-buffered input, allowing the input and DAC registers to be updated independently or simultaneously with a 16-bit serial word. Additional features include software and hardware shutdown, shutdown lockout, a hardware clear pin, and a reference input capable of accepting DC and offset AC signals. These devices provide a programmable digital output pin for added functionality and a serial-data output pin for daisy-chaining. All logic inputs are TTL/CMOS-compatible and are internally buffered with Schmitt triggers to allow direct interfacing to optocouplers.

The MAX5171/MAX5173 incorporate a proprietary on-chip circuit that keeps the output voltage virtually "glitch free," limiting the glitches to a few millivolts during power-up. Both devices are available in 16-pin QSOP packages and are specified for the extended (-40°C to +85°C) temperature range. The MAX5171/MAX5173 are pin-compatible upgrades to the 12-bit MAX5175/MAX5177. For 100% pin-compatible DACs with an internal reference, see the 13-bit MAX5132/MAX5133 and the 12-bit MAX5122/MAX5123 data sheets.

MAX5171 Breakout Board

Product Details

Digital-to-analog converters (DACs) provide accurate output voltages for actuation and control in many electronic applications such as industrial, medical and RF systems. The MAX5171 is a highly accurate, 14-bit voltage output DAC. Development with DACs involves expertise in analog systems, power supplies, digital interfaces, and firmware. Now, accelerate the development process using the MAX5171 breakout board.

This breakout board provides rapid prototyping and development with the MAX5171 (a 14-bit, voltage-output DAC). It interfaces to any Arduino®-compatible or Mbed™-compatible platform system with expansion ports configurable for SPI communication. Additionally, the MAX5171 breakout board works with systems that have a Pmod™ connection, a 2x6 right-angle header at board edge (compatible with Digilentinc.com Pmod interface spec) interface type 2A (expanded SPI) on 2x6 header at board edge. The breakout board also comes with schematics, design files, and firmware for immediate use and forking to future projects.

The board directly interfaces to SPI with logic levels in the range 2.7V to 5.5V. (Note: The MAX5171 is specified for 4.5V to 5.5V operation, and the pin-compatible MAX5173 is specified for 2.7V to 3.6V operation.) The board comes installed with MAX5171AEEE+ installed. Example firmware is provided for Arduino and Mbed system boards.

Applications

  • Automated Test Equipment (ATE)
  • Digital Gain and Offset Control
  • Digitally Programmable 4mA–20mA Current Loops
  • Industrial Process Controls
  • Motion Control
  • Remote Industrial Controls
  • µP-Controlled Systems
