IC CODEC PORTABLE INTERNET 28QFN

Manufacturer: Cirrus Logic Inc.

Categories: CODECS

Quality Control: Learn More

Cirrus Logic WM8731CSEFL is a high-performance, low-power stereo audio CODEC with integrated headphone and microphone amplifiers. This device features 24-bit resolution for both analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), offering typical dynamic ranges of 90 dB for ADCs and 95 dB for DACs. The signal-to-noise ratios are rated at 90 dB for ADCs and 100 dB for DACs. The WM8731CSEFL supports a serial data interface and utilizes a Sigma-Delta architecture. Its supply voltage ranges from 1.8V to 3.6V for analog and 1.42V to 3.6V for digital circuits. The component is housed in a 28-QFN (5x5) package with an exposed pad, suitable for surface mounting. Typical applications for this CODEC include portable internet devices, audio playback systems, and digital audio players. It operates within an ambient temperature range of -40°C to 85°C.

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.
