The ADA8282 is designed for applications that require low cost, low power, compact size, and flexibility. The ADA8282 has four parallel channels, each including a low noise preamplifier (LNA) and a programmable gain amplifier (PGA). The LNA and PGA combine to form a signal chain that features a gain range of 18 dB to 36 dB in 6 dB increments with a guaranteed minimum bandwidth of 5 MHz.
Using the highest power settings, the combined input referred voltage noise of the combined LNA and PGA channel is 3.4 nV/√Hz at maximum gain.
The ADA8282 can be configured in four power modes that trade off power and noise performance to optimize the performance according to the end application.
Fabricated in an advanced complementary metal-oxide semiconductor (CMOS) process, the ADA8282 is available in a 5 mm × 5 mm, RoHS-compliant, 32-lead LFCSP. It is specified over the automotive temperature range of −40°C to +125°C.

Evaluation Kits (1)
The ADA8282CP-EBZ is designed to aid in the evaluation of the ADA8282 radar receive path analog front-end (AFE). The board connects to the system demonstration platform (SDP) for easy configuration of registers through SPI, along with headers to allow configuration using other platforms. It also includes on-board options to provide manual reset capability to the part.
This user guide provides quick start instructions for working with the board.
Full specifications for the ADA8282 are available in the product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
