Analog front end IC from ADI for automotive radars

ADI's has released Analog Front End(ATE) IC for automotive radars. The AD8283 includes the receive path signal conditioning and data capture circuitry supporting designing of adaptive cruise control, blind spot detection and other radar-based detection and avoidance systems.

"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."

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-O or 200-kO selectable input impedance and consumes only 170-mW per channel.
