6.3.1 Digital-to-Analog Converter (DAC) Architecture

Each output channel in the DACx1416 consists of an R-2R ladder architecture followed by an output buffer amplifier capable of rail-to-rail operation. The output amplifiers drive 25 mA with 1.5-V headroom from either VCC or VSS while maintaining the specified TUE specification for the device. The full-scale output voltage for each channel are individually configurable to the following ranges:

  • –20 V to +20 V
  • –10 V to +10 V
  • –5 V to +5 V
  • –2.5 V to +2.5 V
  • 0 V to 40 V
  • 0 V to 20 V
  • 0 V to 10 V
  • 0 V to 5 V

Figure 6-1 shows a block diagram of the DAC architecture.

A. The DAC trigger is generated by either by writing 1 to the LDAC bit or by the LDAC pin in synchronous mode. In asynchronous mode, the DAC latch is transparent.
