BU9253FS-E2 Integrated Circuits (ICs)

The BU9253FS-E2 is an audio special purpose component that offers integrated analog audio input conversion with high performance, low power usage, and a high level of integration. In audio applications, the BU9253FS-E2 can be used to convert analog audio signals into digital signals before being processed by a digital signal processor (DSP).

The BU9253FS-E2 utilizes a multi-bit A/D converter with a high speed analog input amplifier. The A/D converter is capable of 32-bit/96kHz sampling-rate digital data output, resulting in extremely high audio signal-to-noise ratios (SNR) and dynamic ranges. With its low power usage, the BU9253FS-E2 allows audio designs to conserve power and reduce the system-level cost of ownership. The low integration level and the high mounting density of the BU9253FS-E2 also helps to save space and simplify the design at the system level.

The BU9253FS-E2 is also equipped with a simple analog-front-end system and a serial peripheral interface (SPI) to support direct connection with a DSP for low-latency processing. This allows for efficient audio processing and system latency reduction. The BU9253FS-E2 supports common codecs like PCM, dPCM, and ADPCM to meet the requirements of today’s popular audio applications.

The BU9253FS-E2 is mainly used in audio and sound systems, including portable audio and sound devices, automotive audio systems, household audio systems, and applications that require a wide range and low noise/distortion. The application field is also extended to digital signal processing (DSP) and voice recognition applications, as well as audio streaming, such as wirelessly streaming audio, due to its high-performance, low-power, and integrated design.

The BU9253FS-E2 works by taking analog audio input signals, amplifying them, and then converting them into digital data by a multi-bit A/D converter. The A/D converter is capable of 32-bit, 96-kHz sampling-rate, which ensures accurate and clear audio recordings. The amplified signal is sent to a DSP for further processing, with data obtained from the converter transferred via an SPI signal. Once processed, the digital audio output can be produced in a variety of codecs. The BU9253FS-E2 also offers a noise suppressing capability, allowing for clearer and crisper sound reproduction.

The BU9253FS-E2 is an ideal choice for audio special purpose applications, offering high performance and low power consumption. With its integrated design and support for a range of codecs and audio applications, the BU9253FS-E2 can enable manufacturers to create cost-effective audio/sound systems with superior audio quality.
