Audio Codec Codec Chip GX2601 Replaces ES8311 in Car DV Applications

Audio codecs contain analog-to-digital converters and digital-to-analog converters running on the same clock. It can be used in sound cards to support audio input and output. The GX2601 GX2601 is a low-power, single-channel audio codec with a fully differential output that supports programmable analog inputs in a fully differential configuration. The recording path contains a fully differential input, low noise programmable gain amplifier and ALC that is PIN TO PIN compatible with the ES8311.

During recording, the GX2601 eliminates noise with built-in programmable filters. The playback path includes a mono DAC, programmable volume control and fully differential outputs. The chip is optimized for voice/playback and is well suited for surveillance and voice applications.

GX2601 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.

3, DAC: 24-bit, 8 to 96kHz sampling frequency, 95dB signal-to-noise ratio, -85dB THD + N, a pair of differential analog outputs, dynamic range compression, pop and click noise suppression

4, low power consumption: 1.8V to 3.3V operating voltage, low standby current
