Mingjiada Electronics Recycle Cirrus CS4272 192kHz 24-Bit Stereo Audio Codec

Cirrus CS4272 114dB 24-bit 192kHz Stereo Codec: Second-hand Market Trends and Specification Analysis (Mingjiada Electronics)
Abstract: The CS4272 is a high-performance stereo audio CODEC launched by Cirrus Logic, supporting 24-bit/192kHz, 114dB dynamic range and -100dB THD+N. It is widely used in digital mixing consoles, car audio systems, DVD recorders and set-top boxes. Mingjiada Electronics has long been engaged globally in the high-value buyback of Cirrus CS4272 chips, the supply of genuine stock, and the procurement of surplus components. We specialise in professionally assessing the value of audio IC inventory and rapidly realising the value of companies’ idle component assets.

I. CS4272 Chip Positioning and Key Specifications
The CS4272 is a fully integrated stereo codec featuring dual ADCs and dual DACs. It utilises a differential analogue architecture and a multi-bit delta-sigma structure, achieving a dynamic range of 114 dB when powered by a 5 V analogue supply.
Key electrical parameters are as follows:
Full model number: CS4272-CZZ
Resolution: 24-bit
Sampling rate: Up to 192 kHz
DAC/ADC dynamic range: 114 dB (typical)
THD+N: -100 dB
Analogue supply voltage (VA): 4.75 V to 5.25 V
Digital supply voltage (VD): 3.1 V to 5.25 V
Logic interface level: Directly compatible with 2.5 V to 5 V
Package: 28-pin TSSOP (lead-free, pin-compatible with CS4271)
Operating Modes: Stand-Alone mode / I²C and SPI control port modes
On-chip Resources: On-chip oscillator, digital loopback, soft-slope volume (1 dB steps), high-pass/DC offset calibration

II. Technical Highlights of the CS4272
Differential analogue architecture: The CS4272 employs a differential analogue architecture that effectively suppresses common-mode noise, thereby delivering unrivalled analogue performance.
On-chip oscillator: The chip integrates an on-chip oscillator that is automatically enabled in the absence of an external master clock. This eliminates the need for an external crystal oscillator circuit, reducing design costs and PCB space requirements whilst simplifying system design.
Intelligent Volume Control: The digital volume control output supports soft ramp and zero-crossing technologies, enabling smooth volume transitions without pop noise.
Flexible Digital Filters: The device offers selectable digital filter responses and low-latency digital filter options, and supports high-pass filtering or DC offset calibration to meet the requirements of various audio processing scenarios.
Wide-Voltage Logic Interface: The integrated level shifter supports direct interfacing with logic levels ranging from 2.5 V to 5.0 V, facilitating integration with digital systems operating in different voltage domains.
Master/Slave Mode Support: Supports both master and slave modes of operation and is compatible with various serial audio interface formats, including I²S and left-justified.

III. Typical Application Scenarios
Thanks to its wide dynamic range, negligible distortion and outstanding sound quality, the CS4272 is widely applicable in the following fields:
Digital mixing consoles: Provides high-fidelity analogue-to-digital and digital-to-analogue conversion in multi-channel audio mixing systems;
Audio effect processors: Provides a low-latency, high-precision audio path for professional audio effects processors;
DVD recorders and set-top boxes: Meets the demand for high-quality audio codecs in consumer electronics;
Car audio systems: The automotive Class D variant is designed to withstand the demanding conditions of in-vehicle environments;
Computer audio systems: Serves as the core codec component for high-fidelity audio interfaces.

IV. Mingjiada Electronics’ CS4272 Component Business Scope
High-price buyback of Cirrus CS4272
We purchase brand-new, original CS4272-CZZR components from factories clearing out surplus stock, traders with stagnant inventory, and projects with cancelled surplus materials, giving priority to items in original packaging, tubes or reels; we also buy back the full range of Cirrus audio codec chips. We offer on-site valuation for bulk stock and settle payments in cash.
Spot Supply of Genuine CS4272 Chips
We maintain a stable supply chain for genuine, original CS4272 chips. We rigorously verify the production dates and packaging integrity of all materials to meet the needs of repair work and small-batch replenishment requirements.
Long-Term Procurement of Idle Audio ICs
We are continuously seeking to purchase audio codecs, audio DACs/ADCs and audio processing chips from brands such as Cirrus, TI, ADI and ESS. If you have idle stock, please provide the model, quantity, packaging and batch information for a quick valuation.

If you require assistance with disposing of Cirrus CS4272 stock, or are seeking a source of genuine products for this model, please provide the model, quantity, batch and photographs of the actual items to request a quotation. We are also open to discussing long-term partnerships for the recycling of various audio chips and spot purchases.
