speakers. The PAM8823 is capable of driving Stereo 25W (BTL) each 7W 2CH into 8Ω <1% THD+N to a pair of 8Ω load speaker or Mono 50W (PBTL) to a 4Ω load 10W 2CH into 4Ω <1% THD+N speaker operating at 24V supply without external heat-sink or fan Loudspeaker Output Power@18V for Stereo
requirement at playing music. 15W 2CH into 8Ω <1% THD+N Loudspeaker Output power@24V for stereo With embedded Audio DSP to support advanced features as volume 25W 2CH into 8Ω <1% THD+N control, 30 EQ bands, audio mixing, 3D surround sound and Dynamic Loudspeaker PSNR 108dB, DR 108dB @24V
Range Control (DRC), the PAM8823 is capable to provide a high- 16/18/20/24-bits Input with I2S, Left-Alignment & Right-Alignment quality audio output with flexible digital audio processing capability. Data Format Support
These features are fully programmable via a simple I2C control Multiple Sampling Frequencies (fS), Including interface, with robust protection circuits to protect PAM8823 from 8/32/44.1/48/64/88.2/96/128/176.4/192kHz
damage by accidental erroneous operating condition. These Support Stereo 2 Channels or Mono by PBTL Configuration
protection features include Short-Circuit (SCP), Over-Temperature Digital Audio Processor Features Include
(OTP), Over-Voltage (OVP) & Under-Voltage-Lockout (UVLO) 30 Bands Configurable Parametric Speaker EQ protections. Volume Control (+24dB to -103dB, 0.125dB/Step) Dynamic Range Control with Power Clipping The PAM8823 is also pop-free designed during instantaneous power Three-Band Configuration plus Post Dynamic Range Control on/off or mute/shut down switching by anti-pop circuit built-in. The Programmed 3D Surround Sound & Channel Mixing PAM8823 is a slave-only device receiving all clocks from external Noise Reduction Control & Bass/Treble Tone Control sources or internal PLL built-in. It is capable to support sampling rate Level Meter and Power Meter Support from 8kHz to 192kHz. With oversampling technology combined with I2S SDATAO Outputs Selectable for Audio Monitoring, Sub- an advanced noise shaper design, the PAM8823 provides a flat noise Channel or Echo Cancellation (Only by TSSOP-24EP (Type floor and excellent dynamic range from 20Hz to 20kHz.
