Audio Codec Chip GX8311 Applied to Smart Toys, Replaces ES8311

In some smart toys with interactive game functions, for example, the toys can record children‘s voices as part of the game session, such as mimicking voices, guessing the source of the voice, and other interactive games, to increase the motivation and fun for children to participate in the game. At the same time, children can record their own voices through the microphone on the toys as personalized voice prompts or sound effects for the toys, making the toys more personalized and unique.

Audio Codec chip is a high-performance, low-power audio codec in smart toys with a variety of applications, this paper recommends the use of GXSC Audio Codec chip GX8311 to replace the ES8311 in smart toys, GX8311 in the price advantage, the performance is also excellent.

The GX8311 is a low-power mono audio codec with fully differential outputs and support for programmable analog inputs in a fully differential configuration. The recording path contains a fully differential input, a low-noise programmable gain amplifier, and an automatic gain control (ALC) to ensure that the sound can be recorded clearly. Noise is eliminated during the recording process by a built-in programmable filter. The playback path includes a mono DAC, programmable volume control and fully differential output.

Audio Codec chip GX8311 main performance introduction:
