DAC8803 Datasheet Digital-to-analog Converter

Manufacturer: Texas Instruments

Overview: DAC8803 www.ti.com SBAS340C – JANUARY 2005 – REVISED FEBRUARY 2006 Quad, Serial Input 14-Bit Multiplying Digital-to-Analog.

General Description

The DAC8803 is a quad, 14-bit, current-output digital-to-analog converter (DAC) designed to operate from a single +2.7-V to 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

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