ZHCSQ41A August 2022 – December 2022 DAC82002
PRODUCTION DATA
Each output channel in the DAC82002 device consists of a segmented R-2R architecture. Figure 7-1 shows a block diagram of the DAC architecture. The four MSBs of the 16-bit data word are decoded to drive 15 switches, E1 to E15. Each of these switches connects one of 15 matched resistors to either AGND or VREF. The remaining 12 bits of the data word drive switches S0 to S11 of a 12-bit voltage mode R-2R ladder network.
