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.
Features and BenefitsInput referred noise of 4.5 nV/√Hz at 18.3 mW per channel Input referred noise of 3.6 nV/√Hz at 34.8 mW per channel Input referred noise of 3.4 nV/√Hz at 54.8 mW per channel | Application SpecificSPICE Models |
