Analog Devices AD6659
The AD6659 operates from a single 1.8 V analog power supply and features a separate digital output driver supply to accommodate 1.8 V to 3.3 V logic families. The AD6659 is packaged in a 64-lead RoHS-compliant LFCSP that is pin compatible with the AD9269 16-bit ADC, the AD9268 16-bit ADC, the AD9258 14-bit ADC, the AD9251 14-bit ADC, the AD9231 12-bit ADC, and the AD9204 10-bit ADC, enabling a simple migration path between 10-bit and 16-bit converters sampling from 20 MSPS to 125 MSPS.
