HC-55564
The following typical performance distortion graphs were
realized with the test configuration of Figure 7. The
measurement vehicle for Total Harmonic Distortion (THD)
was an HP-339A distortion measurement set, and for 2nd
and 3rd harmonic distortion, an HP-3582A spectrum
analyzer. All measurement conditions were at V
DD
= 5V, and
2nd and 3rd harmonic distortion measurements were C-
message filtered. 0dB = 1.2V
RMS
.
