Analog Devices has extended its portfolio of analog-to-digital converters (ADCs) with a 12-bit monolithic, 20/40/65 MSPS ADC that consumes 40 percent less power than comparable devices. 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. 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.

The AD9237 20/40/65 MSPS ADCs are available now and priced between $7.75 and $12.40 per unit in 1,000-piece quantities. The devices are offered over the wider industrial temperature range (-40oC to +85oC) and are packaged in a 5 mm x 5 mm 32-pin LFCSP (lead frame chip scale package).
