About Audio CODEC ICs

Audio CODECs (Coder-Decoders) are essential for converting analog sound signals into digital data and vice versa. These integrated circuits form the core of any system requiring audio capture or playback, acting as the critical bridge between microphones/speakers and digital processors. Their quality directly impacts fidelity, noise levels, and overall user experience.

In professional audio equipment, CODEC selection determines critical parameters like dynamic range, total harmonic distortion, and sampling accuracy. Advanced features such as Cirrus Logic’s Sigma-Delta modulation enable superior noise shaping and filtering, making these ICs indispensable for applications where audio clarity is non-negotiable.

Packaging

Available in manufacturer tube packaging for secure handling and storage.

Frequently Asked Questions

Q: Is this IC suitable for new designs despite being obsolete?
A: While functional for prototyping and repairs, we recommend consulting PCX engineers for modern alternatives in production systems.

Q: Does the 105dB dynamic range apply to both recording and playback?
A: Yes, the specification applies equally to both the ADC (recording) and DAC (playback) sections.

Q: What voltage compatibility does the digital interface support?
A: The digital supply accepts 3.14V to 5.25V, offering compatibility with 3.3V and 5V logic systems.

Q: Can this CODEC process microphone signals directly?
