This device converts analog audio into standard I2S digital audio, providing a straightforward path from 3.5 mm analog sources to I2S-capable audio systems. Key benefits Preserves high-resolution audio: Supports host operation at 24‑bit / 192 kHz and 24‑bit / 96 kHz to maintain audio detail when digitizing analog signals. Simple analog input: Accepts a 3.5 mm analog input for easy connection to phones, players, mixers, or other line-level sources. Direct I2S output: Converts analog signals to I2S so you can feed digital downstream devices (DACs, processors, FPGAs) without additional converters. Flexible clocking: I2S ADC supports master or slave mode, allowing you to use the module with external clocks or let it provide the clock, simplifying integration with different system architectures. Integration-friendly: Designed for use as a conversion front-end where a clean, standard I2S output is required from analog inputs. Key attributes Function: Analog-to-I2S conversion (ADC to I2S). Compatibility: 3.5 mm analog input compatible with common consumer and professional analog sources; I2S output compatible with I2S receivers. Performance: Operates with host sample rates of 24‑bit/192 kHz and 24‑bit/96 kHz. Clocking modes: Configurable I2S ADC master or slave operation to match system timing requirements. Typical applications Digital audio systems: Convert the analog output of a player, smartphone, or preamplifier via 3.5 mm input to an I2S stream for a digital signal processor or DAC. High-resolution recording front end: Capture analog sources at 24‑bit/96 kHz or 24‑bit/192 kHz and deliver a standardized I2S output to recording hardware or FPGA-based recorders. Embedded or development use: Provide an easy analog-to-I2S interface when integrating analog sensors or audio stages into I2S-based embedded audio projects; switch ADC between master and slave to match the target clocking scheme. Technical notes Host support: 24 bit / 192 kHz and 24 bit / 96 kHz. Analog input: 3.5 mm connection. Conversion: Analog signals converted to I2S. I2S ADC modes: Supports both master and slave configurations. This module provides a clear, compatible route from common analog sources to I2S digital audio, with high-resolution sample-rate support and flexible clocking for integration into diverse audio systems.
