LTC2224 12-Bit, 135Msps ADC _BDTIC代理LTC2224

LTC2224 12-Bit, 135Msps ADC

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.

DC specs include ±0.4LSB INL (typ), ±0.3LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 0.5LSBRMS.

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 for a wide range of clock duty cycles
