Recently, the first intelligent digital hearing aid chip in China was successfully developed by the Institute of Microelectronics of the Chinese Academy of Sciences. This is the first core SoC chip for hearing aids in China. It is a true single-chip fully integrated hearing aid solution. The chip has passed the hearing test industry test standards, and various performance and power consumption indicators meet the needs of international mid-range hearing aid products. This achievement is of great significance for promoting the development of China's hearing aid industry from manufacturing to innovation. The hearing aid SoC chip uses a single-chip fully integrated solution, where the low noise AFE includes an adaptive preamplifier circuit PGA and a low noise 16-bit ADC; the low power DSP includes a dedicated instruction set processor ASIP and several coprocessors. Based on the SoC chip, a typical hearing aid system can be built with a microphone, speaker, EEPROM, zinc-free battery and a small amount of capacitance. The SoC chip can also be programmed for use in other areas such as sound collection, speech noise reduction, and the like. Anesthesia Medical Co., Ltd. , https://www.jssinoanesthesias.com
