Precision ADCs with size and power at a record low.
In data conversion, analog is everywhere.
18-bits, 1 MSPS, 7 mW, 9 mm2: breakthrough performance for medical, industrial designs
In medical, industrial, instrumentation, and sensor equipment, low-power consumption and portability are critical to performance optimization. That's why our new PulSAR® successive approximation analog-to-digital converters represent milestones in precision data conversion technology. Compared to competitive offerings, these ADCs use less than 5% of the power, and are just 20% the size, while maintaining uncompromised performance in other areas such as ac specifications and dc linearity. This family of converters is ideal for challenging applications that require low heat dissipation, extended battery life, and high channel integration.... more
