Referring back to the analog input, since the entire sam-
pling section of the converter also paused for two clock
cycles, the sampling point for sample 5 is also paused
by two clock cycles, possibly creating a small distur-
bance at the SYNC falling edge. This disturbance is fil-
tered with the digital filter, which makes it less distinct.
If the SYNC falling edge occurred during the same XIN
clock period as the DRDYOUT signal, the disturbance
does not affect the periodic timing since the SYNC
falling edge would demand a pause of zero XIN clock
cycles. Hence, connecting the DRDYOUT of the last
converter to the SYNC inputs of many converters, as
illustrated in Figure 13, aligns the sampling of the con-
verters on the first SYNC falling edge, but does not dis-
turb a regular sampling process for future samples.
See the
Multiple Device Synchronization section for dif-
ferent ways to use the SYNC input.
Transfer Function
Figures 17 shows the bipolar I/O transfer function.
Code transitions occur halfway between successive-
integer LSB values. Output coding is binary, with 1 LSB
= (0.88 x VREFIO) x 2/524,288 in 19-bit mode, (0.88 x
VREFIO) x 2/16,777,216 in 24-bit mode, and (0.88 x
VREFIO) x 2/65536 for the MAX11060.
Power-On Reset
The serial interface, logic, digital filter, and modulator
circuits reset to zero at power-up. The power-on reset
circuit releases this reset no more than 1ms after
VDVDD rises above 2V.
