雷达接收通道AFE：6通道放大器PGA/AAF模数转换器ad8283数据表

　　The AD8283 is designed for low cost， low power， compact size， flexibility， and ease of use. It contains six channels of a low noise preamplifier （LNA） with a programmable gain amplifier （PGA） and an antialiasing filter （AAF） plus one direct-to-ADC channel， all integrated with a single 12-bit analog-to-digital converter （ADC）。 Each channel features a gain range of 16 dB to 34 dB in 6 dB increments and an ADC with a conversion rate of up to 72 MSPS. The combined input-referred noise voltage of the entire channel is 3.5 nV/√Hz at maximum gain. The channel is optimized for dynamic performance and low power in applications where a small package size is critical. Fabricated in an advanced CMOS process， the AD8283 is available in a 10 mm × 10 mm， RoHS-compliant， 72-lead LFCSP. It is specified over the automotive temperature range of −40°C to +105°C.
