AD9060
Performance of the AD9060 has been optimized with an analog
input voltage of ± 1.75 V (as measured at ± V
input range is reduced below these values, relatively larger dif-
ferential nonlinearity errors may result because of comparator
mismatches. As shown in Figure 3, performance of the converter
is a function of ± V
Applying a voltage greater than 4 V across the internal resistor
ladder will cause current densities to exceed rated values and
may cause permanent damage to the AD9060. The design of
the reference circuit should limit the voltage available to the
references.
Analog Input Signal
The signal applied to A
parator cells (see Figure 5). This connection has a typical input
resistance of 7 kΩ and input capacitance of 45 pF. The input
capacitance is nearly constant over the analog input voltage
range as shown in Figure 12, which illustrates that characteristic.
