GXSC Audio Codec Chip Replaces ES8311 in Audio Toys

The audio toy market is evolving from traditional pre-recorded sounds toward intelligent interaction and early childhood education. Cost-effective, highly integrated, low-power audio codecs serve as the core components driving this upgrade, delivering children‘s intuitive experience of sound effects and voice while simplifying design requirements. Children can record their own voices via the toy‘s microphone, enabling personalized voice prompts or sound effects that enhance the toy‘s uniqueness and individuality.

As the core component for “sound capture and playback” in audio toys, the audio codec directly determines the toy‘s sound quality, interaction fluidity, and battery life. The GXSC audio codec chip can replace the ES8311 in smart toy applications. Its high integration and low cost make it highly suitable for the mass production demands of audio toys.

The GXSC audio codec is a low-power monaural chip featuring fully differential outputs. It supports programmable analog inputs in fully differential configurations. The recording path includes a fully differential input, a low-noise programmable gain amplifier, and automatic gain control (AGC), ensuring clear sound capture. During recording, built-in programmable filters eliminate noise. The playback path incorporates a mono DAC, programmable volume control, and fully differential output.
