Analog Devices introduces single-chip automotive radar frontend
May 26, 2011 // Christoph Hammerschmidt
Analog Devices introduced a single-chip front-end device handling different signals for automotive radar equipment, The AD8283 enables adaptive cruise control and blind spot detection in a single, cost-competitive IC.
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, whose integrated inertial sensing iMEMS technology contributed to making airbags a standard automotive safety feature, is now introducing a radar AFE (analog front-end) IC.
ADI's highly integrated AD8283 automotive radar 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.
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-Ω or 200-kΩ selectable input impedance and consumes only 170-mW per channel. As part of a complete radar implementation, the AD8283 can be paired with ADI's ADF4158 PLL (phase locked loop).
