The 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. It allows a radar system to receive a higher number of transmitted signals and decode them for target identification and classification.
The part integrates a 12-bit, 80-Msamples/s A/D converter with 67-dB SNR and 68-dB SFDR. It features on-chip signal conditioning, including a programmable-gain amplifier, low-noise amplifier, and a programmable third-order low-pass elliptic filter. The AFE is gain-programmable via an SPI port in 6-dB steps from 16 to 34 dB and has less than 3.5-nV/√Hz input-referred voltage noise at maximum gain. Housed in a 72-lead, the device also has 200-Ω or 200-kΩ selectable input impedance and consumes only 170 mW per channel. ($12 ea/1,000 — available now.)
