Automotive safety is evolving from passive systems such as seat belts, airbags and crash detection to active sensing networks capable of collision avoidance and accident prevention. Radar is an especially promising active safety improvement and has the potential to significantly reduce the number and severity of distracted driving accidents. Analog Devices, Inc. introduced an affordable high-performance radar system AFE (analog front-end) IC. ADI’s highly integrated AD8283 automotive radar system AFE IC includes the receive path signal conditioning and data capture circuitry to enable end systems for adaptive cruise control, blind spot detection and other radar-based detection and avoidance applications.

Automotive Safety Radar System IC for Intelligent Vehicle Design“Thanks to national vehicle safety legislation, such as the introduction of legislation requiring mandatory installation of ADAS (Advanced Driver Assistance Systems), fewer drivers died on US roads last year than at any time since 1949,” said Thomas Wessel, vice president, automotive group, Analog Devices. “Automotive safety has entered the era of the intelligent vehicle, and affordable in-car radar systems with excellent target classification and range resolution are a key feature of that. As in-car radar moves from a luxury option to a standard safety feature, the AD8283 automotive radar AFE will allow designers to program the settings they need for different operating conditions and meet the automotive industry’s exacting quality and cost requirements.”

The AD8283 is designed for low cost, low power, compact size, flexibility, and ease of use. It contains six channels of a low noise preamplifier (LNA) with a programmable gain amplifier (PGA) and an antialiasing filter (AAF) plus one direct-to-ADC channel, all integrated with a single 12-bit analog-to-digital converter (ADC).
