ZXCD1210
High performance analog input Class D modulator
Description
The ZXCD1210 provides complete control and
modulation functions at the heart of high
efficiency high performance Class D switching
audio amplifier solutions. In combination with
high performance output stages and open or
closed
loop
architectures,
the
ZXCD1210
provides a high performance audio amplifier
with all the inherent benefits of Class D.
The
ZXCD1210
solution
uses
proprietary
circuit design to realise the true benefits of
Class D without the traditional drawback of
poor distortion performance. The combination
of
reference
circuit
designs,
magnetic
component choice and layout are essential to
realising these benefits.
Features
Output power 50W to 500W into 4
THD+N <0.05%
Dynamic range 98dB
Open loop and closed loop reference designs
Frequency response
Subwoofers: ±0.5dB from 10Hz to 250Hz
Full band: ±0.5dB from 20Hz to 20kHz
200kHz PWM frequency
Output drive free of crossover artifacts
QFN16 4x4 package
The ZXCD1210 reference designs provide output
powers up to 500W RMS with typical distortion
and noise of less than 0.05% and a dynamic
range of 98dB. The closed loop designs ensure a
high damping factor and excellent supply
rejection. The open loop designs provide high
performance
in
the
most
economic
implementation.
The closed loop reference designs include
circuits specifically for subwoofer applications
featuring a flat frequency response up to 250Hz.
The open loop designs give the ZXCD1210 the
ability to produce amplifiers with full a 20kHz
bandwidth.
Applications
Subwoofers
Home theatre systems
Multimedia
Wireless speakers
Portable audio
This plot shows the
THD+N versus power
plot for a 500W closed
loop subwoofer
reference design.
THD+N is 0.02%
between 10W and
200W which is
outstanding
performance.
