LTC2188 Datasheet 20msps Low Power Dual Adc

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®2188 is a two-channel simultaneous sampling 16‑bit A/D converter designed for digitizing high frequency, wide dynamic range signals.

It is perfect for demanding communications applications with AC performance that includes 77dB SNR and 90dB spurious free dynamic range (SFDR).

Ultralow jitter of 0.07psRMS allows undersampling of IF frequencies with excellent noise performance.
