ADA8282WBCPZ

ADA8282 is a radar receive path AFE: 4-channel LNA and PGA. This device is designed for applications that require low cost, low power, compact size, and flexibility. It has four parallel channels, each including an LNA and a PGA. The LNA and PGA combine to form a signal chain that features a gain range of 18dB to 36dB in 6dB increments with a guaranteed minimum bandwidth of 5MHz. Using the highest power settings, the combined input referred voltage noise of the combined LNA and PGA channel is 3.4nV/√Hz at maximum gain. It can be configured in four power modes that trade off power and noise performance to optimize the overall performance according to the end application. It is used in application such as automotive radar, adaptive cruise control, collision avoidance, blind spot detection, self parking, electronic bumpers etc.
