The radar (analogue front-end) IC x 3 from Analog Devices includes receive path signal conditioning and data capture circuitry to equip end systems for adaptive cruise control, and blind spot detection applications. The six-channel AFE IC is AEC-Q100 qualified and operates from -40 to +105˚C. It allows a radar system to receive a high number of transmitted signals and decode them for target identification. This translates to more time on target, which improves the radar's ability to resolve the size of the target. The analogue front-end integrates a 12bit ADC with a 67dB SNR and a 68dB spurious-free dynamic range. It features on-chip signal conditioning, including a programmable-gain amplifier, low-noise amplifier, and a programmable, low-pass elliptic filter. The analogue front-end is also gain-programmable through a serial peripheral interface port in 6dB steps from 16 to 34dB.
