Description

Introduction:
NAU88C22YG, a component of Nuvoton's Audio CODEC Series, is a low-power, high-quality CODEC designed for portable and general-purpose audio applications. The product simplifies the implementation of complete audio system solutions by integrating an array of advanced functions, including a 24-bit stereo ADCs and DACs, drivers for speaker, headphone, differential or stereo line outputs, and preamps for stereo differential microphones. The device also incorporates a fractional PLL, enabling the accurate generation of any audio sample rate using a typically available system clock ranging from 8MHz to 33MHz.

Function & Applications:
The NAU88C22YG is versatile and suitable for a variety of applications, including wired/wireless telephony, security systems, mobile telephone hands-free kits, and residential & consumer intercoms. It boasts a standard I2S or PCM audio interface, optional PCM time slot assignment, microphone input, a 5-band Graphic Equalizer, Automatic Level Control (ALC) with a noise gate, and PGA.

Performance Parameters:
Key features of the NAU88C22YG include an SNR (Signal to Noise Ratio) of 89dB @ 0dB gain for both the ADC and DAC, and a THD+N (Total Harmonic Distortion plus Noise) of -78dB @ 0dB gain for the ADC and -84dB @ 20mW, RL=32ohm for the DAC. It also provides an integrated headset driver with 40mW (16Ω / 3.3V), and an integrated BTL speaker driver with 1 W (8Ω / 5V). The device supports a variety of sample rates from 8~192KHz and features programmable ALC, an ADC notch filter, and a programmable high-pass filter.

Package Types, Interface & Pin Configuration:
The NAU88C22YG is accessible through an I2C control interface and comes in a compact QFN-32 (5x5mm) package.

Reliability & Lifespan:
NAU88C22YG guarantees robustness over a broad range of operating conditions. The device operates within a voltage range of 1.65V ~ 3.6V (for VDDC/B) and 2.5V ~ 3.6V (for VDDA). It also performs reliably over a wide temperature range of -40℃ to 85℃.

Standards & Certifications:
NAU88C22YG adheres to standard industrial conformity and regulatory specifications. While the detailed certifications are not explicitly provided, the professional standards upheld by Nuvoton ensures that their products meet the relevant industry standards.

Application Cases & Reference Designs:
Usage of NAU88C22YG in application cases and reference designs primarily involves leveraging its high-quality audio capabilities and versatile functionalities. Specific implementation details might differ based on the use case and system requirements, but all make use of the core performance features of the NAU88C22YG. Please refer to company provided documentation for specific implementation guidance.
