GENERAL DESCRIPTION
The XRD64L43 is two 10-bit, monolithic, 40 MSPS
ADCs. Manufactured using a standard CMOS pro-
cess, the XRD64L43 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 XRD64L43 analog input can be driven with ease
due to the high input impedance.
The design architecture uses 17 time- interleaved 10-
bit SAR ADCs in each converter to achieve high
conversion rate of 40 MSPS minimum. In order to
insure and maintain accurate 10-bit operation with
respect to time and temperature, XRD64L43 incorpo-
rates an auto-calibration circuit which continuously
adjusts and matches the offset and linearity of each
ADC. This auto-calibration circuit is transparent to the
user after the initial 4.2ms calibration (168,000 initial clock
cycles).
