DESCRIPTION
The LTC®2234 is a 135Msps, sampling 10-bit A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2234 is perfect for demanding communications applications with AC performance that includes 60.5dB SNR and 75dB spurious free dynamic range for signals up to 400MHz. Ultralow jitter of 0.15psRMS allows undersampling of IF frequencies with excellent noise performance.
