Cirrus Logic has announced the introduction of the Pro Audio Family, a new series of professional audio converters that initially includes low-power analog-to-digital converters (ADCs) to be followed later this year by digital-to-analog converters (DACs) and an audio codec.
“The Cirrus Logic team has a passion for audio and our newly architected Pro Audio Family offers the truest reproduction of audio sound, from instrument to ear. That is what we mean by true transparency,” says Eddie Sinnott, director of Codecs and Standard Products, Cirrus Logic. “Cirrus Logic’s new high-performance Pro Audio Family will make it easier for customers to design great sounding personalized products that differentiate them in their markets, while being assured they are backed by our top-level engineering and customer support.”
The first products to be introduced are a series of three ADCs aimed at providing transparent audio conversion within a device that is simple to use and integrate. The Cirrus Logic CS5302P stereo ADC, CS5304P four-channel ADC and CS5308P eight-channel ADC are designed to be used in digital mixers, USB audio interfaces, home audio and audio video receivers, musical instruments such as synthesizers, DJ mixers and amplifiers, video recording and automotive applications. The control scheme is designed to be simple, joined by a single power rail and flexible clocking configuration to make the devices easier to integrate for all markets.
“We are looking forward to the new series of pro audio devices from Cirrus Logic,” states Robin Clark, managing director of Allen & Heath. “The performance looks excellent, as always, and the company continues to provide ways for designers to differentiate. In past generations, we appreciated Cirrus Logic’s low latency, which is so important to live stage mixing. Now, we see the low power consumption and new hybrid gain control as key features we can use to enhance our own products in the future.”
Cirrus Logic’s hybrid gain control is designed to reduce pop noise and simplify the customer’s system design. By co-locating the analog and digital gain states within one device, gain transactions between the two are matched. This allows customers to retain their existing mic preamp design as a product differentiator while reducing complexity. The hybrid gain control is suited to all customers implementing mic-pre gain control, such as digital mixing consoles and USB audio interfaces for digital audio workstations as well as other applications.
The re-architected Pro Audio Family is designed to deliver quality performance awithin a 25 mW/ch power budget. The devices being introduced are 32-bit resolution ADCs that support differential analog input with stated sample rates up to 768 kHz. The ADCs use a fifth-order, multibit sigma-delta modulator followed by digital filtering and decimation to provide a dynamic range of 126 dB for the CS5302P and 123dB for the CS5304/8P. Stated THD+N for all products is below -110 dB.
Samples of the CS5302/04/08P ADCs are available to order now. The converters are controllable and configurable using Cirrus Logic’s SoundClearâ Studio software that’s available at the company website. Samples of the DACs and codec will be available to order in December 2023.
