Analog Devices, RF Amplifier, 72-Pin LFCSP

The AD828x Analogue Front End (AFE) device is designed for low cost, low power, compact size, flexibility, and ease of use. It features up to six channels each containing a low-noise preamplifier (LNA), a programmable gain amplifier (PGA) and an anti-aliasing filter (AAF) plus one direct-to-ADC channel, all integrated with a single 12-bit ADC. Automotive applications include: ADAS, Adaptive cruise control, Collision avoidance, Blind-spot detection, Self-parking, Electronic bumpers.

• No of Channels with differential inputs: 4 (AD8285), 6 (AD8283), plus one direct to ADC
• PGA gain programmed via SPI port: +16dB to +34dB in 6dB steps
• AAF (3rd-order low-pass elliptic filter) cut-off frequency programmed via SPI port: 1.0MHz to 12MHz
• ADC: 12-bit @ 72MSPS, spurious-free dynamic range (SFDR): 68dB with 16dB gain
• Power-down mode
• Power supply: Separate +1.8V and +3.3V supplies for Analogue and Digital supply pins
• Operating Temperature Range: -40 to +105°C
• Automotive qualified to AEC-Q100

• 806-7969 AD8283WBCPZ 6-channel AFE
