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 47Ω 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.
