pressure deliver products market faster, design engineers find their design cycle times shrinking. When application's design demands upgrade higher accuracy, there's faster better solution than pin-for-pin compatible ICs.
Analog Devices' ADCs provide several upgrade paths allow designers accomplish performance jump shortest time. family AD747x AD746x, 10-, 12-bit ADCs only compatible with each other, they include smallest 16-bit ADCs market-ADI's AD7940 AD7680. These high performance ADCs combine smallest package size (SOT-23-6) with lowest power dissipation-the 8-bit AD746x dissipates just 0.15 power kSPS.
