CS42L51-DNZ Datasheet/PDFThe CS42L51-DNZ is a low-power stereo digital–to–analog and analog–to–digital converter (DAC/ADC) with a wide variety of uses in various application fields. It is a great solution for multimedia devices and provides a stable, low-power, low-noise audio signal. It is designed to meet the needs of both entertainment and industrial audio applications, such as portable audio players, automotive entertainment systems and medical/security/industrial equipment.
The CS42L51-DNZ’s ADC is a dual channel, high-resolution 24-bit stereo A/D converter. It has a sampling rate of up to 96 kHz and delivers a SNR of 90 dB. The DAC is a 24-bit, low-power stereo DAC with a dedicated anti-aliasing filter. It has a maximum sample rate of 48 kHz and offers a SNR of 103 dB. It also includes a headphone amplifier with a 2x gain boost option and an integrated mute function.
The CS42L51-DNZ provides multiple audio input and output options, including both balanced and unbalanced audio inputs and outputs, as well as both digital and analog inputs and outputs. It also includes a microphone input, giving it even more flexibility. It supports a wide range of audio codecs including MP3, AAC, WMA, and WAV, as well as I2S, PCM and DSD audio formats.
The CS42L51-DNZ also features a number of features designed to increase efficiency, such as a low-power idle mode and an adjustable frequency boost. It also supports programmable dynamic range control and multi-zone dynamic range control. Finally, it features a range of integrated protection features to ensure system stability.
Working Principle
The main principle of operation of the CS42L51-DNZ is its ability to convert digital audio signals into analog signals and vice versa. This is done by connecting the device to the audio source, such as a personal computer, via USB, I2S, PCM or DSD, depending on the audio format. The device then receives the digital audio signals and converts them into analog signals, which are then sent to the receiver or speaker system.
In the reverse direction, the device can be used as an A/D converter. It takes analog audio signals from the microphone or other audio source and converts them into digital audio signals, which can then be sent to a digital audio player.
The CS42L51-DNZ also comes with a range of features to enhance the audio quality. It includes an integrated low-noise amplifier that gives a cleaner, more articulate sound. It also has a range of integrated EQ settings, from flat to bass or treble boost, depending on the user’s preference. The device also includes noise-cancelation, which reduces background noise and improves the sound quality.
Conclusion
The CS42L51-DNZ from Cirrus Logic is a great solution for audio applications. It’s low-power and cost-effective, and its wide range of features makes it suitable for a variety of applications, from portable audio players to car and medical equipment. Its wide range of output and input options, combined with its wide range of audio codecs and features, make it one of the most versatileaudio codecs on the market.
