DESCRIPTION
The LTC®2273/LTC2272 are 80Msps/65Msps, 16-bit A/D converters with a high speed serial interface. They are designed for digitizing high frequency, wide dynamic range signals with an input bandwidth of 700MHz. The input range of the ADC can be optimized using the PGA front end. The output data is serialized according to the JEDEC serial interface for data converters specification (JESD204).
