DESCRIPTION
The LTC®2262-12 is a sampling 12-bit A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2262-12 is perfect for demanding communications applications with AC performance that includes 70.5dB SNR and 88dB spurious free dynamic range (SFDR). Ultralow jitter of 0.17psRMS allows undersampling of IF frequencies with excellent noise performance.
