ing buffers between the ADC outputs and any other circuitry
(74ACQ541, for example). Only one input should be con-
nected to each output pin. Additionally, inserting series re-

sistors of 47

Ω to 100Ω at the digital outputs, close to the

ADC pins, will isolate the outputs from trace and other circuit
capacitances and limit the output currents, which could oth-
erwise result in performance degradation. See Figure 4.
