CS4340A-KSR

ADCs/DACs - Special Purpose Overview

The CS4340A-KSR is a stereo digital-to-analog converter (DAC) from Cirrus Logic, part of the CS4340 family. It features a 24-bit resolution and supports sampling rates up to 192 kHz. The device integrates fourth-order delta-sigma conversion, digital interpolation, and de-emphasis filters for 32, 44.1, and 48 kHz inputs. Key electrical specifications include a dynamic range of 101 dB and total harmonic distortion plus noise (THD+N) of -91 dB. It operates on a single +3.0 V or +5.0 V power supply, consuming approximately 33 mW at 3 V. The component utilizes Popguard technology to minimize audible clicks and pops during power transitions.

• Popguard technology for click and pop suppression
• Low clock jitter sensitivity architecture

ADCs/DACs - Special Purpose Applications

• DVD players
• Set-top boxes
• High-fidelity audio systems

ADCs/DACs - Special Purpose Part Context

The CS4340A-KSR belongs to the Cirrus Logic CS4340 series of stereo DACs. This family includes variants such as the CS4340 and CS4340A, which share similar architectural features but may differ in specific performance metrics like maximum sampling rate or package options. The 'KS' suffix typically denotes a lead-free SOIC-16 package variant within this product line.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements within the same family include the CS4340-KS or CS4340-KSZ. For applications requiring higher sampling rates, the CS4340A series offers support up to 192 kHz. Verify pin compatibility and power supply requirements when substituting.
