Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community DAC8812 SBAS349F – AUGUST 2005 – REVISED JUNE 2016 DAC8812 Dual, Serial-Input 16-Bit Multiplying Digital-to-Analog Converter.

General Description

The DAC8812 is a dual, 16-bit, current-output digitalto-analog converter (DAC) designed to operate from a single 2.7-V to 5.5-V supply.

The applied external reference input voltage VREF determines the full-scale output current.

An internal feedback resistor (RFB) provides temperature tracking for the full-scale output when combined with an external I-to-V precision amplifier.

Key Features

  • 1 Relative Accuracy: 1 LSB Max.
  • Differential Nonlinearity: 1 LSB Max.
  • 2-mA Full-Scale Current ±20%, With VREF = ±10 V.
  • 0.5-μs Settling Time.
  • Midscale or Zero-Scale Reset.
  • Separate 4Q Multiplying Reference Inputs.
  • Reference Bandwidth: 10 MHz.
  • Reference Dynamics:.
  • 105-dB THD.
  • SPI™-Compatible 3-Wire Interface: 50 MHz.
  • Double Buffered Registers to Enable Simultaneous Multichannel Update.
  • Intern.
