GENERAL DESCRIPTION

The XRD66L92 is a 12-bit 2-step high speed

Analog-to-Digital Converter with DNL = +1 LSB and INL = +2.5

LSB. The XRD66L92 contains an internal track and hold which

allows for analog input signals as fast as 5 MHz and can convert

signals at a 1 MSPS rate.

The XRD66L92 operates with a single supply at +3.3 V.

Separate pins for reference ladder terminals and power supplies

allow flexibility for various AIN, DVREF, and power supply ranges.

Data is presented at the serial output port every clock cycle

with a 2.5 cycle pipeline delay. LINV and MINV enable binary

and 2’s complement data formatting. Through the 6 ladder tap

pins, transfer function adjustment, and linearity can be

accommodated.
