Product Summary

The AD9218BSTZ-105 is a dual 10-bit monolithic sampling analog-to-digital converter with on-chip track-and-hold circuits. The AD9218BSTZ-105 is low cost, low power, and is small and easy to use. The AD9218BSTZ-105 operates at a 105 MSPS conversion rate with outstanding dynamic performance over its full operating range. Each channel can be operated independently.
