The Nuvoton NAU88C14YG is a cost-effective and low-power wideband MONO audio CODEC specifically designed for voice telephony related applications. It integrates essential functions such as a 5-band Graphic Equalizer, Automatic Level Control (ALC) with a noise gate, and a Programmable Gain Amplifier (PGA).
Key electrical features include an ADC with 91dB SNR (A-weighted) at 0dB gain and -79dB THD+N, and a DAC with 93dB SNR (A-weighted) at 0dB gain and -84dB THD+N. It supports an integrated headset driver delivering 40mW into 16Ω and an integrated BTL speaker driver capable of 1W into 8Ω.
The device supports standard audio interfaces like I2S and PCM, with sample rates ranging from 2.5KHz to 48KHz. Advanced control features include an ADC Notch Filter, a Programmable High Pass Filter, and an I2C control interface. It operates within a voltage range of 1.71V to 3.6V for VDDB/C and 2.5V to 3.6V for VDDA, with an operating temperature range of -40°C to 85°C.
The NAU88C14YG is available in a compact 24-QFN (4x4mm) surface mount package, making it suitable for space-constrained designs.
