Both products are offered in a low-profile 28-pin TSSOP package, feature 24-bit conversion and support all standard audio sample rates up to 192kHz, making them DVD-Audio ready.īoth solutions operate from a 5V power supply and offer manufacturers the ultimate system flexibility with an on-chip oscillator, output volume control with soft ramp and zero crossing, selectable digital filter response and integrated level shifters for direct interface to logic levels from 2.5V to 5V. The CS4271 employs a single-ended input architecture versus the differential inputs employed by the CS4272, thus achieving 108dB dynamic range on the ADC while maintaining 114dB performance on the DAC. The CS4272 delivers dynamic range of 114dB and -100dB THD+N for both the ADC and DAC. The CS4272 and CS4271 offer the highest analogue performance versus competing market solutions and provide excellent sound quality.
In accomplishing both goals, we believe we have positioned Cirrus to lead in this market category.” The second goal was to offer designers a simplified, cost-reduced solution that accelerates the product’s time to market. “ First was to develop the highest performing chips in the market with superior dynamic range and distortion characteristics.
“ We had two objectives in mind when designing these new CODECs”, said Jason Rhode, director of marketing, Mixed Signal Products, Cirrus. Because both chips share a common footprint, designers can interchange their designs with either solution to vary end-product performance, reduce development costs and accelerate time to market. The CS4272 and CS4271 integrate an analogue-to-digital converter (ADC) and a digital-to-analogue converter (DAC) into a single-chip solution, thereby providing cost-efficiency and system simplification as well as reduced space requirements in board designs. in the Preamplifier project.Ĭurrently, revision 4 of this board ships, which is a major redesign giving even lower noise and distortion.According to Cirrus Logic: “ These products give design engineers a cost-effective, high-performance solution for a wide variety of high-end audio applications such as multi-track recording systems, effects processors, digital mixing consoles, automotive audio systems, digital video recorders and other emerging digital entertainment markets.” Note: the kit contains the components for using the DAC in hardware-mode, it can also be used in software-mode, so it can be controlled from a microcontroller, e.g. Complete kit with all components, SMD components pre-mounted.This product is available with the following options: Onboard output relay to mute the outputs when the supply is not yet stable.Supply needs: Dual 8-12V analog and single 5V digital.More information can be found on the CS4398 DAC project page.
