Audio Codec GX8311 Used in Recording Pen, Replaces ES8311

In the field of digital audio, the sound quality and performance of audio recorders are getting more and more attention from users. The GX8311 low-power mono audio codec...

Supporting 24-bit, 8 to 96kHz sampling frequency, the GX8311 is able to accurately capture and reproduce sound. Whether recording speeches in a meeting, lectures in a classroom, or natural sounds outdoors, every detail can be recorded in high resolution, providing users with clear, lifelike recording results.

The GX8311 features a low-noise preamplifier, whose built-in low-noise preamplifier effectively reduces the interference of ambient noise and enhances the purity of the recording.The ALC function automatically adjusts the gain according to the level of the incoming audio, ensuring a stable recording volume and avoiding the impact on the listening experience due to the sound being too loud or too small. The Noise Gate function automatically closes when the sound falls below a certain threshold, further reducing unwanted noise and improving the quality of the recording.

Audio Codec chip GX8311 main performance introduction:

1, system: high-performance low-power 24-bit delta-sigma audio ADC and DAC, I2S/PCM master serial or slave serial data port, 256/384Fs, USB 12/24MHz and other non-standard audio system clock, and I2C interface.

2, ADC: 24-bit, 8 to 96kHz sampling frequency, 95dB signal-to-noise ratio, -93dB THD + N, a pair of differential analog inputs, low-noise programmable gain amplifiers, automatic level control (ALC) and noise gate, support for analog and digital microphones.

DAC: 24-bit, 8 to 96kHz sampling frequency, 95dB SNR, -85dB THD+N, one pair of differential analog outputs, dynamic range compression, pop and click noise suppression. 4, PIN TO PIN compatible with ES8311.

In addition, the GX8311 in the 1.8V to 3.3V operating voltage, playback and recording power is only 14mW, standby current is also very low, which relies on battery-powered recorder, can effectively extend the battery life, reduce the number of times of recharging, so that users do not need to worry about the problem of insufficient power during a long period of time recording.
