The differential output provides the maximum output current when all digital input bits are High. The output current (using binary format) is shown in the following equations.

  • IVOUTP = (BinDataIn / 2N) * IOUTFS
  • IVOUTN = IOUTFS - IVOUTP
  • Vcm=DAC_AVTT - IOUTFS * (0.5+0.08) * 50

where:

  1. BinDataIn = 14-bit digital input
  2. IOUTFS = Full-scale output current
  3. Vcm is the common-mode voltage on each IVOUT leg
