Quality Control: Learn More

The Cirrus Logic WM8731CLSEFL-R is a high-performance stereo audio codec for portable digital audio applications. This 24-bit device features two stereo DAC channels and two stereo ADC channels, offering a typical dynamic range of 90dB for ADCs and 95dB for DACs, with signal-to-noise ratios of 90dB and 100dB respectively. The WM8731CLSEFL-R supports serial data interfaces, including I2S, MSB justified, and LSB justified formats. It operates from analog supply voltages between 1.8V and 3.6V, and digital supply voltages from 1.42V to 3.6V. The codec is housed in a compact 28-QFN (5x5) package and is supplied on tape and reel for surface mounting. This component is widely utilized in consumer electronics, personal audio devices, and communication systems requiring robust audio processing.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
