GENERAL DESCRIPTION

The XRD64L44 is two 10-bit, monolithic, 50 MSPS ADCs. Manufactured using a standard CMOS process, the XRD64L44 offers low power, low cost and excellent performance. The on-chip track-and-hold amplifier(T/H) and voltage reference (VREF) eliminate the need for external active components, requiring only an external ADC conversion clock for the application. The XRD64L44 analog input can be driven with ease due to the high input impedance of RIN = 25KOhms and CIN = 5pF.
