FEATURES
1● Audio Input/Output – 20-W Into an 8-Ω Load From an 18-V Supply – Wide PVCC Range (10 V to 26 V); 3.3 V Digital Supply – Supports One Serial Audio Input (8 kHz - 48 kHz Sample Rates) (LJ/RJ/I2S) – Power-Stage Feedback Allows Operation From Poorly Regulated Power Supplies
● Audio/PWM Processing – Factory-Trimmed Internal Oscillator for Automatic Rate Detection – High-End 32-Bit Data Path Audio Processor – 14 Biquads for Speaker EQ – Dynamic Range Control (DRC)
● Benefits – EQ: Speaker Equalization Improves Audio Performance – DRC: Enables Speaker Protection and Night-Mode Listening. – Autobank Switching: Preloaded Coefficients for Three Different Sample Rates Eliminates the Need to Update Coefficients When Sample Rate Changes – Autodetect: Automatically Detects Sample-Rate Changes Eliminating the Need for External Microprocessor Intervention – Closed-Loop Power Stage: Enables Wide PVCC Operating Range and Reduced Power Supply Ripple Distortion
DESCRIPTION
A 32-bit datapath eliminates the need for pre-scaling before processing and preserves signal integrity without sacrificing dynamic range.
