General Description
The CS43L22 is a highly integrated, low power stereo DAC
with headphone and Class D speaker amplifiers. The
CS43L22 offers many features suitable for low power, porta-
ble system applications.
The DAC output path includes a digital signal processing en-
gine with various fixed function controls. Tone Control
provides bass and treble adjustment of four selectable corner
frequencies. Digital Volume controls may be configured to
change on soft ramp transitions while the analog controls can
be configured to occur on every zero crossing. The DAC also
includes de-emphasis, limiting functions and a BEEP genera-
tor delivering tones selectable across a range of two full
octaves.
The stereo headphone amplifier is powered from a separate
positive supply and the integrated charge pump provides a
negative supply. This allows a ground-centered analog output
with a wide signal swing and eliminates the need for external
DC-blocking capacitors.
The Class D stereo speaker amplifier does not require an
external filter and provides the high efficiency amplification re-
quired by power sensitive portable applications. The speaker
amplifier may be powered directly from a battery while the in-
ternal DC supply monitoring and compensation provides a
constant gain level as the battery’s voltage decays.
The CS43L22 accommodates analog routing of the analog in-
put signal directly to the headphone amplifier. This feature is
useful in applications that utilize an FM tuner where audio re-
covered over-the-air must be transmitted to the headphone
amplifier directly.
In addition to its many features, the CS43L22 operates from a
low voltage analog and digital core making it ideal for portable
systems that require extremely low power consumption in a
minimal amount of space.
The CS43L22 is available in a 40-pin QFN package in Com-
mercial (-40 to +85 °C) grade. The CS43L22 Customer
Demonstration board is also available for device evaluation
and implementation suggestions. Please refer to “Ordering In-
formation” on page 66 for complete ordering information.
