Product Details
The AD8283 is designed for low cost, low power, compact size, flexibility, and ease of use. It contains six channels of a low noise preamplifier (LNA) with a programmable gain amplifier (PGA) and an antialiasing filter (AAF) plus one direct-to-ADC channel, all integrated with a single 12-bit analog-to-digital converter (ADC).
Each channel features a gain range of 16 dB to 34 dB in 6 dB increments and an ADC with a conversion rate of up to 80 MSPS. The combined input-referred noise voltage of the entire channel is 3.5 nV/√Hz at maximum gain. The channel is optimized for dynamic performance and low power in applications where a small package size is critical.
Fabricated in an advanced CMOS process, the AD8283 is available in a 10 mm × 10 mm, RoHS-compliant, 72-lead LFCSP. It is specified over the automotive temperature range of −40°C to +105°C.
