Tripath Technology, Inc. - Technical Information  
The measurements of certain performance parameters, particularly noise related specifications  
such as THD+N, are significantly affected by the design of the low-pass filter used on the output  
as well as the bandwidth setting of the measurement instrument used. Unless the filter has a  
very sharp roll-off just beyond the audio band or the bandwidth of the measurement instrument is  
limited, some of the inaudible noise components introduced by the Tripath amplifiers switching  
pattern will degrade the measurement.  
One feature of the TA2024B is that it does not require large multi-pole filters to achieve excellent  
performance in listening tests, usually a more critical factor than performance measurements.  
Though using a multi-pole filter may remove high-frequency noise and improve THD+N type  
measurements (when they are made with wide-bandwidth measuring equipment), these same  
filters degrade frequency response. The TA2024B Evaluation Board uses the Test/Application  
Circuit in this data sheet, which has a simple two-pole output filter and excellent performance in  
listening tests. Measurements in this data sheet were taken using this same circuit with a limited  
bandwidth setting in the measurement instrument.
