The LTC2205-14 is a sampling 14-bit A/D converter designed for digitizing high frequency, wide dynamic range signals up to input frequencies of 700MHz. The input range of the ADC can be optimized with the PGA front end.
The LTC2205-14 is perfect for demanding communications applications, with AC performance that includes 78.3dB SNR and 98dB spurious free dynamic range (SFDR). Ultralow jitter of 90fsRMS allows undersampling of high input frequencies with excellent noise performance. Maximum DC specs include ±1.5LSB INL, ±1LSB DNL (no missing codes).
A separate output power supply allows the CMOS output swing to range from 0.5V to 3.6V.
The ENC+ and ENC– inputs may be driven differentially or single-ended with a sine wave, PECL, LVDS, TTL or CMOS inputs. An optional clock duty cycle stabilizer allows high performance at full speed with a wide range of clock duty cycles.
