Digital To Analog Converters datasheet and documents for CS43L43-KZZR

CS43L43-KZZR

Digital To Analog Converters Overview

The CS43L43-KZZR is a low voltage stereo digital-to-analog converter (DAC) manufactured by Cirrus Logic. It integrates interpolation, 1-bit D/A conversion, analog filtering, volume control, and a headphone amplifier within a single 16-pin TSSOP package. The device supports 24-bit resolution with sample rates up to 96 kHz. It operates on a supply voltage ranging from 1.8 V to 3.3 V. Key performance metrics include a dynamic range of 94 dB at 3 V supply and -85 dB THD+N at 1.8 V supply. The component features digital volume control with 96 dB attenuation in 1 dB steps, digital bass and treble boost capabilities, and peak signal limiting.

Digital To Analog Converters Feature Summary

Integrated headphone amplifier providing up to 22 mWrms power output into a 16 Ω load
Digital signal processing including bass/treble boost, de-emphasis, and peak signal limiting
Low power consumption design suitable for portable applications
Zero crossing click-free level transitions for mute and volume adjustments

Digital To Analog Converters Applications

Portable audio players and MP3 devices
Mobile phones and handheld communication devices
Personal media players requiring integrated headphone driving

Digital To Analog Converters Procurement Notes

Verify the specific suffix KZZR against official Cirrus Logic documentation to confirm tape-and-reel packaging configuration. Confirm end-of-life status or obsolescence notifications prior to procurement planning. Ensure compatibility with existing serial interface protocols used in the target design.

Digital To Analog Converters Selection Notes

Select this component when a compact solution combining high-fidelity DAC conversion with direct headphone amplification is required. Verify that the 1.8 V to 3.3 V operating voltage aligns with the system's power rails. Consider the 16-pin TSSOP package constraints for PCB layout and thermal management requirements.

Digital To Analog Converters Part Context

The CS43L43 belongs to Cirrus Logic's low-voltage audio DAC family designed for portable electronics. It serves as an integrated output stage solution, eliminating the need for external amplifiers in many mobile designs. The part is distinct from higher-channel-count or higher-sample-rate variants in the broader CS43xx series.
