ON Semiconductor launched a non-fitting/TWS earphone listening solution. Among them, the OTC (non-fitting) hearing aid solutions have two platforms: "OTC hearing aid" and "OTC wireless hearing aid". For these two platforms, ON Semiconductor provides differentiated technical support. For the OTC hearing aid platform, ON Semiconductor provides the original schematic design, BOM, algorithm firmware, microphone, speaker, DSP and other separation solutions; the integrated module includes the microphone speaker DSP, EEPROM and other peripheral power circuits and algorithm firmware. OTC wireless hearing aid platform, ON Semiconductor provides reference design, BOM, algorithm firmware, applet, APP, cloud fitting, TV streamer and other separation solutions; integrated modules include DSP, low-power Bluetooth and storage, clock chips, etc.

For the TWS headset listening solution, ON Semiconductor B300+ Bluetooth platform provides B300 algorithm firmware, hardware reference design, hearing aid + phone function solution, algorithm interface, etc.; J10+ Bluetooth platform provides J10 basic algorithm firmware, hardware reference design, algorithm interface, hearing aid and Phone function, applet, cloud fitting program and mobile APP, etc.

Introduction of ON Semiconductor B300/B300M platform:

ON Semiconductor B300/B300M platform is based on the wide dynamic compression processing of syllable processing, can be configured with 1~16 processing channels, the frequency band can be divided freely, can be independently configured in-channel fast and slow time detector, channel feedback detection suppression processing. In addition, ON Semiconductor B300/B300M platform based on long-term speech spectrum speech enhancement algorithm, short-term spectrum analysis intelligent noise reduction algorithm, optional memory switching or automatic switching, realize digital volume control, low battery prompt, support direct audio input, Bluetooth audio input, etc.

ON Semiconductor J10 Wireless OTC Hearing Aid Module:

ON Semiconductor J10 wireless OTC hearing aid module has a 5mm * 4mm * 1.2mm ultra-small package, no need for peripherals, can work after power on, integrated hardware module, suitable for a variety of application implementation, ultra-low power BLE 5.0 Bluetooth technology and other characteristics. It also integrates the complete solution of Pre-configure hearing aid algorithm firmware, supports wireless fitting, supports 4-channel WDRC algorithm, supports voice noise reduction technology, supports high-pass filtering algorithm, provides mobile APP/WeChat applet, provides schematic diagrams, firmware and other "interchangeable". Key" complete design.

ON Semiconductor J11 Wireless OTC Hearing Aid Platform:

The basic algorithm of ON Semiconductor J11 wireless OTC hearing aid platform includes customization up to 4-channel WDRC, different levels of noise reduction algorithm, 16-channel EQ customization, adaptive filter, low-power audio transmission protocol, Fourier transform algorithm, etc.

Features: 16KHz sampling rate, audio transmission current 1.2mA, hearing aid mode 1.44mA, 1.61mA BLE+HA mode, 15ms sound delay, audio transmission at a distance of 15 meters from TV companion, rechargeable, pure tone audiometry, automatic fitting , remote microphone, etc.

ON Semiconductor is a leading supplier of hearing aid chips in the industry. After the U.S. FDA released the draft OTC hearing aid specification, the OTC hearing aid market has attracted much attention. Many manufacturers have joined this market one after another. The OTC hearing aid solution launched by ON Semiconductor will significant impact on this market.
