ADC10321 10-Bit, 20MSPS, 98mW A/D Converter with Internal Sample and Hold

Check for Samples: ADC10321

FEATURES

DESCRIPTION

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 reference buffer

amplifier to ensure optimal accuracy. No missing

codes is ensured over the full operating temperature

range. The unique two stage architecture achieves

9.2 Effective Bits with a 10MHz input signal and a

20MHz clock frequency. Output formatting is straight

binary coding.

APPLICATIONS

•

Digital Video

Communications

Document Scanners

Medical Imaging

Electro-Optics

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 consumption 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, imaging, communications,

multimedia and high speed data acquisition. 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.
