ADC10030 10-Bit, 30 MSPS, 125 mW A/D Converter with Internal Sample and Hold
General Description
The ADC10030 is a low power, high performance CMOS analog-to-digital converter that digitizes signals to 10 bits resolution at sampling rates up to 30 Msps while consuming a typical 125 mW 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.
1 Effective Bits with a 15 MHz input signal and a 30 MHz clock frequency.
Output formatting is straight binary coding.
To ease interfacing to 3V systems, the digital I/O power pins of the ADC10030 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 4 mW.
The ADC10030’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 ADC10030 for high speed portable applications, and its speed and resolution are ideal for charge coupled device (CCD) input systems.
The ADC10030 comes in a space saving 32-pin TQFP and operates over the industrial (−40˚C ≤ TA ≤ +85˚C) temperature range.
