High Speed, High Accuracy, Low Power ADCs for Efficient Precision Control

Today's designs for motor control and automotive applications require ADCs that have high speed to digitize auxiliary input/output signals, real-time results output to the processor, and simultaneous sampling to maintain correct phase information. Meeting these needs in a compact footprint is a challenge faced by all IC suppliers.

AD7356

Solution
The AD7356 12-bit, 5 MSPS, dual-channel simultaneous sampling ADC is unlike any other SAR ADC that ADI offers. It is 25% faster than other single-channel SAR ADCs in the 12-bit resolution range and 3× faster than the next fastest simultaneous sampling SAR ADC.

The higher data throughput rate offered by the AD7356, with no limitation on time between conversions, provides a key performance advantage for devices where continuous measurement of motor functions is required to maintain precision operation. One such application is optical encoders used in high speed industrial motor controls. ADI also offers an extended portfolio of high performance products offering lower speed or increased channel count to suit all design needs. Pair ADI's AD8022 ADC driver with the AD7356 for optimal low noise driving.
