CS42L56-CNZR

CS42L56-CNZR Application Field and Working Principle

The CS42L56-CNZR is a high performance, ultra-low power audio codec that is ideal for a variety of applications and supports a wide range of audio formats. It is based on Cirrus’ second-generation 32-bit core architecture, and is optimized for both low power and low latency. The codec is available in a 3.3 V, 25-bump, 0.4 mm pitch CSBGA package option.

The CS42L56-CNZR integrates an Audio Codec, a Digital-to-Analog Converter (DAC) and an Analog-to-Digital Converter (ADC). It supports 24-bit audio with sample rates up to 192 kHz and provides many features, including ADC offset and gain compensation and automatic data clocking. The digital audio interface supports single-ended, dual-ended and stereo I2S/TDM digital audio modes.

One of the most essential features of the CS42L56-CNZR audio codec is its low power consumption. The codec consumes only 44 mW in full power mode and only 2 mW in low power mode. This makes it ideal for applications where long battery life is essential. Moreover, the codec utilizes a low-noise I/O pin configuration, reducing interference from other components. It also features advanced power management, allowing the device to enter low-power states when not in use.

The CS42L56-CNZR also offers excellent audio performance. It supports high sample rate audio with up to 24-bit resolution and is capable of providing 114 dB SNR. It also features a dedicated headphone amplifier, which offers a 20 dB headroom and a maximum output level of 4 Vrms. The CS42L56-CNZR also features 6-bit programmable digital volume control with up to 128 steps of attenuation.

The CS42L56-CNZR audio codec is an excellent choice for applications requiring high-quality audio with low power consumption. It supports a wide array of audio formats with 24-bit resolution and a sample rate up to 192 kHz. Its low power consumption and high performance make it ideal for portable applications. The CS42L56-CNZR also features a dedicated headphone amplifier, low-noise I/O pin configuration and advanced power management, allowing it to enter low-power states when not in use.
