Overview
The AD7923SRUZ-EP-RL7 is a 12-bit, high-speed, low-power successive approximation register (SAR) analog-to-digital converter featuring four single-ended inputs with a channel sequencer. It operates from a single 2.7 V to 5.25 V supply and supports throughput rates up to 200 kSPS. The device includes a wide-bandwidth track-and-hold amplifier handling input frequencies exceeding 8 MHz. It utilizes a flexible serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. The component is housed in a 16-lead TSSOP package and is qualified for military temperature ranges from −55°C to +125°C.
Feature Summary
- Enhanced product qualification supporting defense and aerospace applications under AQEC standards with controlled manufacturing baselines.
- Integrated channel sequencer allowing preprogrammed sequential conversion of four single-ended analog inputs.
- VDRIVE function enabling direct connection to 3 V or 5 V processor systems independent of the analog supply voltage.
- Flexible power management with auto shutdown and full shutdown modes minimizing current consumption during idle periods.
Applications
- Aerospace and defense systems
- Military communications (Milcom)
- Avionics instrumentation
- Unmanned aerial systems
Procurement Notes
Verify that the specific ordering suffix matches the required packaging format, as the RL7 designation indicates reel packaging. Confirm that the enhanced product status aligns with project requirements for defense and aerospace qualifications. Ensure compatibility with the specified military temperature range and controlled manufacturing baseline before finalizing procurement decisions.
Selection Notes
Select this component when a 12-bit resolution and 200 kSPS throughput are required for multi-channel signal acquisition. The integrated sequencer simplifies system design by reducing microprocessor overhead for channel switching. Consider the VDRIVE feature if interfacing with logic levels distinct from the analog supply voltage. Verify that the external reference voltage meets the specified 2.5 V ±1% requirement for optimal performance.
Part Context
This part belongs to the AD7923-EP family of enhanced products designed specifically for rugged environments. Unlike standard commercial variants, the EP version adheres to strict quality controls including single assembly and fabrication sites. It shares core electrical specifications with the non-EP AD7923 but offers extended reliability data and change notification protocols essential for long-life defense applications.
Replacement Considerations
The AD7923SRU-EP serves as the tube-packaged equivalent. Standard commercial versions like the AD7923BRUZ lack the enhanced product features and military temperature rating. Direct pin-compatible substitutes outside the AD7923 family require verification of serial interface timing and input range specifications.
