LTC2268-12 Datasheet Low Power Dual Adcs

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC2268-12/ LTC2267-12/LTC2266-12 12-Bit, 125Msps/105Msps/ 80Msps Low Power Dual.

General Description

The LTC®2268-12/LTC2267-12/LTC2266-12 are 2-channel, simultaneous sampling 12-bit A/D converters designed for digitizing high frequency, wide dynamic range signals.

They are perfect for demanding communications applications with AC performance that includes 70.6dB SNR and 88dB spurious free dynamic range (SFDR).

Ultralow jitter of 0.15psRMS allows undersampling of IF frequencies with excellent noise performance.
