DESCRIPTION
The LTC®2224 is a 135Msps, sampling 12-bit A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2224 is perfect for demanding communications applications with AC performance that includes 67.3dB SNR and 80dB spurious free dynamic range for signals up to 150MHz. Ultralow jitter of 0.15psRMS allows undersampling of IF frequencies with excellent noise performance.
