AD9218SSTZ-105EPRL

Overview

The AD9218SSTZ-105EPRL is a dual, 10-bit monolithic sampling analog-to-digital converter (ADC) operating at 105 MSPS. It features on-chip track-and-hold circuits and requires only a single 3.0 V supply. The device provides 300 MHz analog bandwidth per channel with an SNR of 54 dB at 51 MHz. It supports TTL/CMOS compatible digital outputs and includes power-down modes for individual channels. Packaged in a 48-lead LQFP, it is rated for the extended industrial temperature range of −55°C to +105°C.

Procurement Notes

Verify that the specific ordering suffix matches the required package variant and reel configuration. Confirm compliance with AQEC standards for defense applications. Ensure the extended temperature rating aligns with system environmental requirements before finalizing procurement orders.

Selection Notes

Select this component when high-speed dual-channel conversion is required within a compact footprint. Consider the 1 V p-p input range and 3 V supply constraints during system design. Evaluate thermal resistance values relative to PCB layout capabilities to ensure reliable operation across the full specified temperature range.

Part Context

This part belongs to the AD9218-EP Enhanced Product series designed for aerospace and defense markets. It shares functional similarities with standard commercial variants but adheres to stricter manufacturing controls. The EP designation indicates qualification under the AQEC standard for reliability.

Replacement Considerations

Direct pin-compatible replacements include other members of the AD9218 family. Verify that substitute parts meet the same extended temperature specifications and enhanced product manufacturing baseline requirements.
