GENERAL DESCRIPTION

The XRD6415 is a 10-bit, 20MSPS, Analog-to-Digital

Converter (ADC) for applications that require high speed

and high accuracy. Designed using an advanced CMOS

process, this part offers excellent performance, low

power consumption and latch-up free operation.

The XRD6415 uses a subranging architecture to maintain

low power consumption at high conversion rates. Our

proprietary comparator design achieves a low analog

input capacitance. The input circuitry of the XRD6415

includes an on-chip S/H function that allows the product to

digitize analog input signals between GND and VDD. The

XRD6415 can be placed into power down (stand-by)

mode, reducing the power dissipation to 1.5mW (typical)

by a digitally controlled pin.

Providing external reference voltages allows easy

interface to any input signal range between GND and

VDD. This also allows the system to calibrate out zero

scale and full scale errors by adjusting VRT and VRB. The

Reference Ladder tap (VR2) can be used to externally

trim INL errors.

A separate power supply pin, DVDD, sets the output logic

levels for 3V or 5V interface.

This device operates from a single 5V supply. Power

consumption from a 5V supply is typically 120mW at

FS=15MHz. For 3.3V power supply operation refer to

XRD64L15.
