DAC-08 Digital to Analog Converter module


DT-I /O DAC-08 Digital to Analog Converter (DAC)-based 8-bit AD7302 Single supply module . Compatible with the DT-51 ™ Low Cost Series and DT-51 ™ Minimum System ver 3.0, but did not rule to be applied to the other module microcontroller / microprocessor
This module is suitable for battery powered portable instrument applications, source voltage and current can be programmed, etc..

Specifications:

  • Two DAC with 8-bit resolution.
  • Working voltage (VDD) = +2.7 VDC - +5.5 VDC.
  • Analog output range = 0 - VDD; voltage reference (VREF) = VDD / 2.
  • Low power / w power-down function.
  • Two modes of operation:
  • Automatic Updates (update each DAC output in real-time).
  • Simultaneous Update (update both DAC outputs simultaneously).
  • Operate Rail-to-Rail with a settling time of 1.2 us.
  • Relative accuracy = ± 1 LSB max.
  • Zero code error @ 25 ° C = 3 LSB typ.
  • High-speed parallel interface.
  • On-chip buffer and supports the application of Digital Signal Processing.
  • Can be connected via pin I / O or Intel System Bus.
  • Equipped routines ready for the DT-51 ™ Low Cost Series and DT-51 ™ Minimum System ver 3.0.
  • Dimensions: 4.75 cm  x 4.5 cm  x 1.5 cm
