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 80 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.

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The AD8283CP-EBZ and AD8285CP-EBZ are designed to aid in the evaluation of AD8283 and AD8285 radar receive path ICs. The boards connect to the high speed ADC FIFO evaluation board for ready data capture. They also provide flexible options for clock settings, voltage references, and easy interfaces for input signals.
