产品概述

The MAX5820LEUA+ is a dual, 8bit, 2-wire, serial voltage-output digital to analogue converter (DAC) in 8 pin µMAX package. This device has a serial interface, power-down circuitry, dual input & DAC registers, two 8bit resistors string DACs, two unity-gain output buffers and output resistor networks. The serial interface decodes address and control bits, routing data to the proper input or DAC register. Data can be directly written to DAC register, immediately updating device output or can be written to input register without changing the DAC output. DAC with an I2C compatible 2-wire interface operates at clock rates up to 400KHz. It features a double buffered I2C compatible serial interface, all logic inputs are CMOS logic compatible and buffered with schmitt triggers allowing direct interfacing to optocoupler and transformer isolated interfaces. Device minimizes digital noise feed-through by disconnecting clock (SCL) signal from rest of device when an address mismatch is detected.
  • Supply voltage range is 2.7V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Rail to rail output buffer amplifiers, maximum INL of ±1LSB & DNL of ±0.5LSB
  • Three software-selectable power-down output impedances (100Kohm, 1Kohm and high impedance)
  • Readback mode for bus and data checking, power-on reset to zero
  • PSRR of 58.8dB at Code = FF hex, VDD = 4.5V to 5.5V
  • Wake-up time is 8µs at VDD = 5V
  • DAC to DAC crosstalk of 2.4nV-s, address bit is 0111 00X
  • Supply current with no load of 115µA ( all digital inputs at 0 or VDD = 3.6V)
  • Supply current with no load of 135µA ( all digital inputs at 0 or VDD = 5.5V)
