ADC128S102 MDP

Analog To Digital Converters (ADC) Overview

The ADC128S102QML-SP is a radiation-hardened, eight-channel, 12-bit successive-approximation analog-to-digital converter (ADC) from Texas Instruments. It supports conversion throughput rates ranging from 50 kSPS to 1 MSPS and features an internal track-and-hold circuit. The device accepts independent analog (VA) and digital (VD) supplies, both operating between 2.7 V and 5.25 V. It utilizes a serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. Packaged in a 16-lead ceramic SOIC, it is rated for operation at temperatures up to 125°C and withstands total ionizing doses of 100 krad(Si).

Analog To Digital Converters (ADC) Feature Summary

• Radiation hardened to withstand 100 krad(Si) total ionizing dose.
• Immune to single event latch-up and functional interrupts at 120 MeV-cm2/mg.
• Supports variable power management with independent analog and digital supply pins.
• Compatible with standard serial protocols including SPI, QSPI, MICROWIRE, and DSP interfaces.

Analog To Digital Converters (ADC) Applications

• Satellite attitude and orbit control systems
• Precision sensor data acquisition
• High temperature industrial environments

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and grade. Confirm that the component meets the required MIL-STD-883 quality conformance inspection levels. Ensure the supply voltage ranges align with system requirements before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when radiation hardness is mandatory for space or high-altitude applications. Verify that the 12-bit resolution and 1 MSPS throughput meet signal processing needs. Check compatibility with existing serial bus architectures and ensure adequate thermal management for the ceramic package.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC128S102 family, specifically the QML-SP variant designed for military and aerospace reliability. It shares the core SAR architecture with commercial versions but undergoes rigorous screening for radiation tolerance and extended temperature operation.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other parts within the 5962R07227 family, such as the ADC128S102WGRQV or ADC128S102WRQV, depending on the required package style.
