产品概述

The MAX5722AUA+ from Maxim Integrated Products is a 12bit, low power, dual, voltage output DAC with serial interface in 8 pin µMAX package. This dual buffered DAC consumes 112µA supply current, DAC outputs employ on-chip precision output amplifiers that swing Rail to Rail® and the reference input accepts a voltage range from 0 to VDD. In power-down, the reference input is high impedance, further reducing system's total power consumption. The on-chip power-on reset (POR) circuit resets DAC outputs to zero and loads output with a 100Kohm resistor to ground. This provides additional safety for applications that drive valves or other transducers that need to be off on power-up. Device is used in automatic tuning, gain and offset adjustment, power amplifier control, process control I/O boards, battery-powered instruments and VCO control.
  • Supply voltage range is 2.7V to 5.5V
  • Operating temperature range from -40°C to +125°C
  • Ultra low power consumption of 135µA at VDD = +5.5V
  • 0.3µA power down current
  • Safe power-up reset to zero volts at DAC output
  • Three software selectable power-down impedances (100Kohm, 1Kohm and Hi-Z)
  • Fast 20MHz, 3 wire SPI, QSPI and MICROWIRE compatible serial interface
  • Schmitt-triggered logic inputs for direct interfacing to opt couplers
  • Maximum INL is ±16LSB and maximum DNL is ±1LSB at monotonic
  • Automatic Tuning; Battery-Powered Instruments; Gain and Offset Adjustment; Power Amplifier Control; Process-Control I/O Boards; VCO Control
