(2) A 33 mH inductor was placed in series with the load resistor to emulate a small speaker for efficiency measurements. (3) The 30 kHz low-pass filter is required even if the analyzer has an internal low-pass filter. An R-C low pass filter (100 Ω, 47 nF) is used on each output for the data sheet graphs. 6 Submit Documentation Feedback Copyright © 2010, Texas Instruments Incorporated Product Folder Link(s): TPA2015D1 |
