ADC10321

10-Bit, 20MSPS, 98mW A/D Converter with Internal

Sample and Hold

General Description

Features

n Internal Sample-and-Hold

n Single +5V Operation

n Low Power Standby Mode

n Guaranteed No Missing Codes

n Tri-State Outputs

The ADC10321 is a low power, high performance CMOS

analog-to-digital converter that digitizes signals to 10 bits

resolution at sampling rates up to 25Msps while consuming

a typical 98mW from a single 5V supply. Reference force

and sense pins allow the user to connect an external refer-

ence buffer amplifier to ensure optimal accuracy. No missing

codes is guaranteed 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 TTL/CMOS or 3V Logic Input/Output Compatible

Key Specifications

n Resolution

10 Bits

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

of the ADC10321 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 4mW. The

ADC10321’s speed, resolution and single supply operation

makes 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

ADC10321 for high speed portable applications, and its

speed and resolution are ideal for charge coupled device

(CCD) input systems.
