AD9218SSTZ-105-EP

Overview

The AD9218SSTZ-105-EP is a dual 10-bit monolithic sampling analog-to-digital converter (ADC) designed for defense and aerospace applications. It operates at a maximum conversion rate of 105 MSPS with a typical Signal-to-Noise Ratio (SNR) of 54 dB at 51 MHz. The device features a 300 MHz full-power analog bandwidth and consumes 275 mW per channel. It utilizes a single 3.0 V supply (2.7 V to 3.6 V range) and includes an on-chip track-and-hold circuit and reference. The component is housed in a 48-lead, 7 mm × 7 mm Low Profile Quad Flat Package (LQFP) and supports an extended industrial temperature range from −55°C to +105°C.

Feature Summary

• Supports defense and aerospace applications through controlled manufacturing baselines and qualification data availability.
• Features dual channels with independent operation capabilities and low crosstalk between channels.
• Includes user-selectable power-down modes, digital data formats, and output alignment schemes.

Applications

• Radar systems
• Avionics
• Unmanned systems
• Military communications
• Missiles and munitions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with your design requirements. Confirm that the extended industrial temperature range and enhanced product features align with your project specifications. Check for any updates regarding qualification data availability or assembly site information before finalizing procurement plans.

Selection Notes

Select this component when high dynamic performance and wide operating temperature ranges are required for critical applications. Ensure the system can accommodate the 48-lead LQFP package dimensions and thermal characteristics. Verify that the 1 V p-p differential input range and TTL/CMOS compatible outputs match the interface requirements of the downstream logic and upstream signal sources.

Part Context

This part belongs to the AD9218-EP Enhanced Product family, which is specifically tailored for rugged environments. It shares architectural similarities with standard commercial variants but offers stricter manufacturing controls and broader temperature coverage. The EP designation indicates adherence to AQEC standards, ensuring traceability and reliability for mission-critical deployments.

Replacement Considerations

The AD9218SSTZ-105EPRL is a reel-based version of the same component, offering identical electrical and mechanical specifications. Designers requiring tape-and-reel packaging for automated assembly should consider this alternative without modifying the schematic or layout.
