Product Summary

The AD9218BSTZ is a dual 10-bit monolithic sampling analog-to-digital converter with on-chip track-and-hold circuits. The device is low cost, low power, and is small and easy to use. The AD9218BSTZ operates at a 105 MSPS conversion rate with outstanding dynamic performance over its full operating range. Each channel can be operated independently. The device requires only a single 3.0 V (2.7 V to 3.6 V) power supply and an encode clock for full operation. No external reference or driver components are required for many applications. The applications of the AD9218BSTZ include Battery-Powered Instruments, Hand-Held Scopemeters, Low Cost Digital Oscilloscopes, I and Q Communications, Ultrasound Equipment.
