ADA8282 Quad Channel LNA & PGA AFE
Analog Devices ADA8282 Analog Front End (AFE) features four parallel channels. Each channel includes a low noise preamplifier (LNA) and a programmable gain amplifier (PGA). The LNA and PGA combine to form a signal chain that offers a gain range of 18dB to 36dB in 6dB increments with a guaranteed minimum bandwidth of 5MHz. When using the highest power settings, the combined input referred voltage noise of the LNA and PGA channel is 3.4nV/√Hz at maximum gain. Designers can configure the ADA8282 AFE using four power modes which trade off power and noise performance to optimize the performance based on the end application. Specified over the automotive temperature range of −40°C to +125°C, the ADA8282 AFE is well-suited for automotive radar, adaptive cruise control, collision avoidance, blind-spot detection, self-parking, and electronic bumper applications.
