ADI 5962-9451801MLA
- Complete 12-bit successive approximation ADC with on-chip buried Zener reference
- Fast conversion time: 5 µs (AD7572XX06) or 12.5 µs (AD7572XX12) versions
- Low power CMOS operation: 135 mW typical
- Fast bus access time: 90 ns for direct microprocessor interface
- MIL-PRF-38535 qualified under SMD 5962-94518 — no external trim required
- Military temperature range: –55°C to +125°C
The ADI 5962-9451801MLA is the military SMD procurement designation for Analog Devices' AD7572S — a complete LC2MOS 12-bit analog-to-digital converter that integrates everything needed for high-speed data acquisition in a single 24-pin ceramic package. It combines a successive-approximation conversion architecture with an on-chip buried Zener reference and an on-chip clock circuit, eliminating the external reference, clock source, and signal conditioning components that competing solutions require. The result is a genuinely complete ADC: the only external components needed for basic operation are power supply decoupling capacitors.
What makes the AD7572S particularly well suited to military signal chain designs is the combination of speed and integration at low power. With a 5 µs conversion time in the fast variant and 135 mW CMOS power consumption, it fits the performance envelope of high-throughput data acquisition systems without the thermal management overhead of bipolar alternatives. The on-chip buried Zener reference delivers stable, low-drift performance across the full –55°C to +125°C military temperature range without user trimming — a significant advantage in field-deployed systems where calibration access is limited. The 5962-9451801MLA part number provides the standardized DoD acquisition path with full MIL-PRF-38535 qualification documentation.

Twelve-bit resolution, 5 µs conversion, and a complete on-chip signal chain — the ADI 5962-9451801MLA brings the proven AD7572S architecture into the DoD qualified parts ecosystem under MIL-PRF-38535. For military procurement teams, the SMD number provides a standardized acquisition path with lot traceability and certificate of conformance. For engineers, the device eliminates the design complexity of external references and clock circuits that typically accompany discrete ADC implementations — everything needed for a functional 12-bit conversion channel is already on the die.
5962-9451801MLA Architecture: LC2MOS Successive Approximation with On-Chip Reference
The AD7572S uses a successive-approximation architecture with an internal high-speed DAC and comparator loop to achieve its fast conversion times. The on-chip buried Zener reference — the same technology Analog Devices uses in its precision reference products — provides a stable voltage source that performs consistently across the military temperature range without user adjustment. An on-chip clock circuit supports both crystal-controlled stand-alone operation and synchronization to an external microprocessor clock, giving system designers flexibility in how they integrate the device into their timing architecture. The 90 ns bus access time enables direct interface to most military microprocessors and DSPs without additional buffering or glue logic.
5962-9451801MLA vs AD7572S: Military vs Commercial Procurement
Engineers familiar with the commercial AD7572S will find the 5962-9451801MLA electrically and functionally identical — the distinction is entirely in qualification and documentation. The military SMD designation means the device has been processed and screened to MIL-PRF-38535 requirements, with qualification test data, lot traceability, and certificate of conformance available for each shipment. For defense programs procuring from a qualified sources list, the 5962-9451801MLA is the correct acquisition path. Programs that also use the 5962-9078501MLA precision voltage reference will find the two devices complement each other naturally in precision signal chain designs.

Frequently Asked Questions (FAQ)
What Is the ADI 5962-9451801MLA and What Is Its Commercial Equivalent?
The 5962-9451801MLA is the military SMD procurement designation for Analog Devices’ AD7572S — a complete LC2MOS 12-bit successive approximation ADC with on-chip buried Zener reference and clock circuit, qualified to MIL-PRF-38535 under drawing 5962-94518, rated for military operation from –55°C to +125°C.
What Does “Complete” Mean for the AD7572S?
The AD7572S integrates the ADC core, a buried Zener voltage reference, and a clock circuit on a single die. The only external components required for basic operation are power supply decoupling capacitors. This level of integration simplifies board design, reduces component count, and eliminates the performance variability introduced by external reference and clock components in discrete implementations.
What Is the Difference Between the 5962-9451801MLA and the Commercial AD7572S?
The electrical specifications are identical. The 5962-9451801MLA designation indicates MIL-PRF-38535 processing and screening, with full qualification documentation including lot traceability and certificate of conformance — required for DoD programs procuring from the qualified sources list. The commercial AD7572S does not carry this qualification documentation.
Can the 5962-9451801MLA Interface Directly With a Microprocessor?
Yes. The AD7572S features a 90 ns bus access time and a direct microprocessor-compatible parallel interface that connects to most military microprocessors and DSPs without additional buffering or glue logic. It also supports synchronization to an external microprocessor clock, enabling tight integration with the host system’s timing architecture.
