Audio Amplifiers datasheet and documents for CS4525-CNZ

CS4525-CNZ

Audio Amplifiers Overview

The CS4525-CNZ is a stereo Class D amplifier system with an integrated stereo analog-to-digital converter. It delivers up to 15 W per channel into 8 Ω speakers from a 48-pin QFN package, achieving greater than 85% efficiency without requiring a heatsink. The ADC supports 24-bit resolution at 48 kHz conversion rates with a 95 dB dynamic range. The device features configurable outputs including parallel full-bridge (1 x 30 W), full-bridge (2 x 15 W), and half-bridge configurations. It includes built-in protection against overcurrent, undervoltage, and thermal overload.

Audio Amplifiers Feature Summary

Fully integrated power MOSFETs eliminate the need for external components or heatsinks.
Integrated sample rate converter synchronizes fixed PWM switching frequencies regardless of input sample rates.
Configurable output topologies support various speaker impedance requirements and power levels.
Built-in digital signal processing provides parametric EQ, tone control, and bass management.

Audio Amplifiers Applications

Integrated Digital TVs
Flat Panel TV Monitors
Digital Powered Speakers

Audio Amplifiers Procurement Notes

Verify the specific suffix 'CNZ' corresponds to the commercial grade (-10°C to +70°C) variant in the manufacturer's ordering information. Confirm that the 48-pin QFN package dimensions align with your PCB layout constraints. Ensure the design accommodates the required thermal pad dissipation characteristics specified in the datasheet.

Audio Amplifiers Selection Notes

Select this component when a high-efficiency audio solution requires both amplification and analog-to-digital conversion in a single package. The integrated SRC simplifies clocking architectures by removing jitter effects. Consider the programmable foldback feature for managing thermal conditions in enclosed spaces without active cooling.

Audio Amplifiers Part Context

This part belongs to Cirrus Logic's digital audio amplifier family designed for consumer electronics. It combines power stage capabilities with advanced digital signal processing. The integration reduces overall bill of materials and board space compared to discrete solutions.
