Applications information
The high performance ZXCD1210 modulator IC forms the heart of the Zetex series of analog input
Class D amplifier reference designs. The modulator device provides complete control of the
modulation function.
Details of these reference designs are contained in individual data sheets: ZXCDSUBEV series,
ZXCD50STEVAL and ZXCD100MOEVAL as well as the ZXCD series design guide.
The ZXCDSUBEV series of reference circuits are specifically designed for subwoofer applications.
These switching amplifiers owe much of their outstanding audio performance to a unique
feedback architecture designed to reduce distortion. By taking its feedback signal from the filtered
amplifier output, the high gain circuit design compensates for bridge mismatches and filter non-
linearities, to achieve a reduction in THD+N across the entire power band.
