ADC10221
Description
The ADC10221 is the first in a family of low power, high performance 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 m W from a single 5V supply. Reference force and sense pins allow 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 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 ADC10221 can be tied to a 3V power source, making the outputs 3V patible. 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 m W.
