●Product Details
●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.
