For high-volume production applications, the software includes an auto-test mode; for design verification and R&D applications, BlueAudio displays an audio FFT, frequency response curves, and THD+N against level and THD+N against frequency.
Implemented in a complete power amplifier design, the LME49811's total harmonic distortion plus noise (THD+N) is 0.00035 percent, while the LME49830's THD+N is 0.0006 percent.
It provides-110 dB THD+N and [+ or -]0.008 dB flatness; measurements including level, THD+N, harmonic distortion, IMD, FFT, frequency response, multitone, crosstalk, histogram, jitter amplitude and spectrum; and the QuickMeas capability.
