ADC12DL066

Dual 12-Bit, 66 MSPS, 450 MHz Input Bandwidth A/D

Converter w/Internal Reference

General Description

Features

n Single +3.3V supply operation

n Internal sample-and-hold

n Outputs 2.4V to 3.3V compatible

n Pin compatible with ADC12D040

n Power down mode

The ADC12DL066 is a dual, low power monolithic CMOS

analog-to-digital converter capable of converting analog in-

put signals into 12-bit digital words at 66 Megasamples per

second (MSPS), minimum. This converter uses a differential,

pipeline architecture with digital error correction and an on-

chip sample-and-hold circuit to minimize die size and power

consumption while providing excellent dynamic performance

and a 450 MHz Full Power Bandwidth. Operating on a single

3.3V power supply, the ADC12DL066 achieves 10.7 effec-

tive bits and consumes just 686 mW at 66 MSPS, including

the reference current. The Power Down feature reduces

power consumption to 75 mW.

— Operating

The differential inputs provide a full scale differential input

swing equal to 2 times V_REFwith the possibility of a single-

ended input. Full use of the differential input is recom-

mended for optimum performance. The digital outputs from

the two ADCs are available on separate 12-bit buses with an

output data format choice of offset binary or two’s comple-

ment.

Applications

n Ultrasound and Imaging

n Instrumentation

n Communications Receivers

n Sonar/Radar

n xDSL

n Cable Modems

n DSP Front Ends

To ease interfacing to lower voltage systems, the digital

output driver power pins of the ADC12DL066 can be con-

nected to a separate supply voltage in the range of 2.4V to

the digital supply voltage.

This device is available in the 64-lead TQFP package and

will operate over the industrial temperature range of −40˚C to

+85˚C. An evaluation board is available to ease the evalua-

tion process.
