SNAS186B –APRIL 2003–REVISED MARCH 2013

ADC12020 12-Bit, 20 MSPS, 185 mW A/D Converter with Internal Sample-and-Hold

Check for Samples: ADC12020

FEATURES

DESCRIPTION

The ADC12020 is a monolithic CMOS analog-to-

digital converter capable of converting analog input

signals into 12-bit digital words at 20 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. Operating

on a single 5V power supply, this device consumes

just 185 mW at 20 MSPS, including the reference

current. The Power Down feature reduces power

consumption to 40 mW.

•

Internal sample-and-hold

•

Outputs 2.35V to 5V compatible

Pin compatible with ADC12010, ADC12040,

ADC12L063 and ADC12L066

•

TTL/CMOS compatible input/outputs

Power down mode

On-chip reference buffer

APPLICATIONS

•

Image Processing Front End

Instrumentation

The differential inputs provide a full scale input swing

equal to 2V_REFwith the possibility of a single-ended

input. Full use of the differential input is

recommended for optimum performance. For ease of

use, the buffered, high impedance, single-ended

reference input is converted on-chip to a differential

reference for use by the processing circuitry. Output

data format is 12-bit offset binary.

PC-Based Data Acquisition

Fax Machines

Waveform Digitizers

Sonar/Radar

DSP Front Ends

This device is available in the 32-lead LQFP package

and will operate over the industrial temperature range

of −40°C to +85°C.
