Product Details

The AD8284 is an integrated analog front end designed for low cost, compact size, flexibility, and ease of use. It contains a 4-channel differential multiplexer (mux), a 1-channel low noise preamplifier (LNA) with a programmable gain amplifier (PGA) and an antialiasing filter (AAF), as well as one direct-to-ADC channel, all integrated with a single, 12-bit analog-to-digital converter (ADC). The AD8284 also incorporates a saturation detection circuit for high frequency overvoltage conditions that would otherwise be filtered by the AAF.

The analog channel features a gain range of 17 dB to 35 dB in 6 dB increments, and an ADC with a conversion rate of up to 60 MSPS. The combined input referred voltage noise 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 AD8284 is available in a 10 mm × 10 mm, RoHS compliant, 64-lead TQFP. It is specified over the automotive temperature range of −40°C to +105°C.
