40% less power
Analog Devices has extended its portfolio of ADCs with a 12-bit monolithic, 20/40/65 MSPS device that, it says, consumes 40% less power than comparable devices.

has extended its portfolio of analog-to-digital converters (ADCs) with a 12-bit monolithic, 20/40/65 MSPS (mega samples per second) ADC that, it says, consumes 40% less power than comparable devices.
Available in a 5 mm x 5 mm package, the AD9237 ADC is an ultra-low power extension of the company’s existing AD9235 family. The device consumes a low 190 mW of power at 65 MSPS, 135 mW at 40 MSPS and 90 mW at 20 MSPS, allowing for a higher channel count and simplified signal path to portable 12-bit systems.
Further power savings is available with a scaling feature, which lowers the power as the speed of the converter is reduced. The AD9237 operates from a single 3 V power supply and features a separate digital output driver supply to accommodate 2.5 V and 3 V logic families.
The AD9237 is pin-to-pin compatible with ADI’s 10-bit AD9215, 12-bit AD9235 and 14-bit AD9245 20/40/65 MSPS ADCs, and also with the 12-bit AD9236 and 14-bit AD9245 80 MSPS ADCs. This enables designers to easily change resolutions and speeds, or upgrade performance in next-generation systems.
