DESCRIPTION
The LTC®2274 is a 105Msps, 16-bit A/D converter with a high speed serial interface. It is 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 specifi cation (JESD204).
