DAC1628D1G25
Objective data sheet
10.13 Auxiliary DACs
The cascode source configuration increases the output impedance of the source, which
improves the dynamic performance of the DAC because there is less distortion.
Depending on the application, the various stages and the targeted performances, the
device can be used for an output level of up to 2 V (p-p).
The DAC1628D1G25 integrates two auxiliary DACs, which are used to compensate any
offset between the DACs and the next stage in the transmission path. Both auxiliary DACs
have a 10-bit resolution and are current sources (referenced to ground).
The full-scale output current for each DAC is the sum of the two complementary current
outputs:
The output current depends on the digital input data set by SPI registers
DAC_A_AUX_MSB (bits AUX_A[9:2]), DAC_A_AUX_LSB (bits AUX_A[1:0]),
DAC_B_AUX_MSB (bits AUX_B[9:2]) and DAC_B_AUX_LSB (bits AUX_B[1:0];
