NAU8814YG Description

Short technical summary and product information.

The Nuvoton NAU8814YG is a versatile mono audio CODEC designed for voice telephony and related applications. It offers 24-bit signal processing with a DAC SNR of 93dB and an ADC SNR of 91dB. The device supports variable sample rates from 2.5kHz to 48kHz and includes an integrated BTL speaker driver capable of 1W into 8 ohms at 5V, as well as a headset driver delivering 40mW into 16 ohms at 3.3V.

 

Key features include a programmable microphone amplifier with a gain range of -12dB to +35.25dB, a standard I2S digital interface, and SPI & 2-Wire serial control interfaces. The analog supply voltage ranges from 2.5V to 3.6V, while the digital core can operate as low as 1.71V. The operating temperature range is -40°C to +85°C.

 

This CODEC is housed in a 24-VFQFN exposed pad package and utilizes surface mount technology. Its analog inputs feature a programmable gain amplifier (PGA) for dynamic range optimization, and it includes functions like a 5-band graphic equalizer and programmable Automatic Level Control (ALC) with a noise gate.
