ADC10221

10-Bit, 15 MSPS, 98 mW A/D Converter with Internal

Sample and Hold

General Description

Features

n Internal Sample-and-Hold

n Single +5V Operation

The ADC10221 is the first in a family of low power, high per-

formance CMOS analog-to-digital converters. It can digitize

signals to 10 bits resolution at sampling rates up to 20 MSPS

(15 MSPS guaranteed) while consuming a typical 98 mW

from a single 5V supply. Reference force and sense pins al-

low the user to connect an external reference buffer amplifier

to ensure optimal accuracy. The ADC10221 is guaranteed to

have no missing codes over the full operating temperature

range. The unique two stage architecture achieves 9.2 Effec-

tive Bits with a 10MHz input signal and a 20MHz clock fre-

quency. Output formatting is straight binary coding.

n Low Power Standby Mode

n Guaranteed No Missing Codes

n TTL/CMOS or 3V Logic Input/Output Compatible

To ease interfacing to 3V systems, the digital I/O power pins

of the ADC10221 can be tied to a 3V power source, making

the outputs 3V compatible. When not converting, power con-

sumption can be reduced by pulling the PD (Power Down)

pin high, placing the converter into a low power standby

state, where it typically consumes less than 4 mW. The

ADC10221’s speed, resolution and single supply operation

make it well suited for a variety of applications in video, im-

aging, communications, multimedia and high speed data ac-

quisition. Low power, single supply operation ideally suit the

ADC10221 for high speed portable applications, and its

speed and resolution are ideal for charge coupled device

(CCD) input systems.
