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 guaranteed 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.

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.

The ADC10321 comes in a space saving 32-pin TQFP and operates over the industrial (-40°C T_A +85°C) temperature range.
