The Nuvoton NAU88C22YG is a versatile stereo audio CODEC designed for portable and general-purpose audio applications. It offers precision 24-bit stereo Analog-to-Digital Converters (ADCs) and Digital-to-Analog Converters (DACs), providing high-quality audio performance with an SNR of 89dB for both ADC and DAC.
This device integrates essential audio functions, including drivers for speakers and headphones, and preamplifiers for microphones, reducing the need for external components. It supports a wide range of sample rates from 8kHz to 192kHz and features a fractional PLL for accurate clock generation. The CODEC operates within a voltage range of 1.65V to 3.6V (VDDC/B) and 2.5V to 3.6V (VDDA), with an operating temperature range of -40°C to 85°C.
The NAU88C22YG is available in a compact 32-QFN (5x5mm) package, making it suitable for space-constrained designs. Its I²C control interface allows for easy integration and configuration of advanced features like a 5-band graphic equalizer, programmable ALC, ADC notch filter, and high-pass filter.
Key applications include wired/wireless telephony, security systems, mobile telephone hands-free kits, and residential intercoms. The integrated headset driver can deliver 40mW into a 16Ω load, and the BTL speaker driver can output 1W into an 8Ω load.
