PAM8823 Data Brief
25Wx2 STEREO/50Wx1 MONO DIGITAL AUDIO AMPLIFIER WITH EQ & DRC Description Features The PAM8823 is a high efficiency, Stereo 25W / Mono 50W Class D
digital audio amplifier with I2S input to drive stereo bridge-tied
speakers. The PAM8823 is capable of driving Stereo 25W (BTL) each
to a pair of 8Ω load speaker or Mono 50W (PBTL) to a 4Ω load
speaker operating at 24V supply without external heat-sink or fan
requirement at playing music. With embedded Audio DSP to support advanced features as volume
control, 30 EQ bands, audio mixing, 3D surround sound and Dynamic
Range Control (DRC), the PAM8823 is capable to provide a highquality audio output with flexible digital audio processing capability.
These features are fully programmable via a simple I2C control
interface, with robust protection circuits to protect PAM8823 from
damage by accidental erroneous operating condition. These
protection features include Short-Circuit (SCP), Over-Temperature
(OTP), Over-Voltage (OVP) & Under-Voltage-Lockout (UVLO)
protections. The PAM8823 is also pop-free designed during instantaneous power
on/off or mute/shut down switching by anti-pop circuit built-in. The
PAM8823 is a slave-only device receiving all clocks from external
sources or internal PLL built-in. It is capable to support sampling rate
from 8kHz to 192kHz. With oversampling technology combined with
an advanced noise shaper design, the PAM8823 provides a flat noise
floor and excellent dynamic range from 20Hz to 20kHz.
The PAM8823 is packaged in 48-pin, L-QFP7070-48EP (Type A1) or
TSSOP-24EP (Type A1). Applications Flat Monitor & LCD TVs …
