Useful analog front end in energy storage

What is an analog front end (AFE)?

Integrated into battery management systems (BMS), an analog front end (AFE) digitizes and processes key inputs to ensure safe and efficient operation. Review BMS specifications and features of AFEs.

What is an analog front end (AFE) in BMS?

The analog front end (AFE) is a key component in BMS, especially in battery management AFE. This monitoring chip has multiple sampling channels and can monitor voltage and temperature to keep the battery healthy. In the AFE circuit, parts like a 16-bit ADC, a high-precision voltage reference, and a multiplexer work together.

What is the frequency range of the analog front end?

The design of an active front end that delivers good pulse response and low distortion from DC up to frequencies of 500 MHz (and beyond) is challenging. This issue of the Analog EdgeSM will provide a few design ideas and suggestions for an analog front end for use with high-perform-ance ADCs suitable for high-speed data capture.

Is an analog front end suitable for high-speed data capture?

The design of an active front end for use with high-performance ADCs suitable for high-speed data capture is challenging. This issue of the Analog EdgeSM will provide a few design ideas and suggestions for an analog front end that delivers good pulse response and low distortion from DC up to frequencies of 500 MHz (and beyond).

Can an analog front end be used with high-performance ADCs?

This issue of the Analog EdgeSM provides design ideas and suggestions for an analog front end suitable for high-speed data capture with high-performance ADCs. The preferred method of interfacing high-frequency analog signals to the input of an ADC is through the use of differential amplifiers.

What are the top analog front-end manufacturers in the world?

Globally, core analog front-end (AFE) manufacturers mainly include Analog Devices, Inc. (ADI), Texas Instruments, Microchip Technology, ST Microelectronics, Cirrus Logic, and NXP. In 2021, the top echelon manufacturers are mainly ADI and TI. Together, they hold about 60% of the market share.
