Advanced Automotive Radar Helps Car Makers Increase Driver Safety Through Intelligent Vehicle Design
Analog Devices' analog front-end for automotive radar enables adaptive cruise control and blind spot detection in a single, cost-competitive IC.
NORWOOD, Mass.--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. (NYSE: ADI), whose integrated inertial sensing iMEMS® technology helped make airbags a standard automotive safety feature over 15 years ago, is introducing an affordable, high-performance, radar AFE (analog front-end) IC today.

"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. "This is largely due to the fact that 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."
Performance Radar in an AEC-Q100 Qualified IC
The six-channel AD8283 is AEC-Q100 qualified and operates over the -40°C to +105°C automotive temperature range. The new device allows a radar system to receive a higher number of transmitted signals and decode them for target identification and classification. This translates to more time on target, which improves the radar's ability to resolve the approximate size of the target.
The AD8283 integrates a 12-bit, 80-MSPS (million samples per second) A/D converter with 67-dB SNR (signal-to-noise ratio) and 68-dB SFDR (spurious-free dynamic range). It features on-chip signal conditioning, including a programmable-gain amplifier, low-noise amplifier, and a programmable, third-order, low-pass elliptic filter. The AD8283 is gain-programmable via an SPI port in 6-dB steps from 16 dB to 34 dB and has <3.5nV/rtHz input-referred voltage noise at maximum gain. The new AFE has 200-W or 200-kW selectable input impedance and consumes only 170-mW per channel.
