Q
Does charge-pump noise affect the signal quality of the ADA4500 output?
A
The ADA4500’s charge pump operates at a very fast clock speed, varying between3.5 MHz and 5MHz over its supply voltage range. This high frequency does not
show up in the usual lower-frequency input signal of the ADA4500. Its noise and
distortion are limited only by the input signal and the thermal or flicker
noise.
