Overview
The ADM1051JR is a dual-channel, precision voltage regulator controller manufactured by Analog Devices Inc. Designed for personal computer motherboard applications, it generates power rails and implements active bus termination. The device integrates a 1.2 V precision bandgap reference and two control amplifiers. It operates within an input voltage range of 11.28 V to 12.72 V, with a nominal rating of 12 V. The component is housed in an 8-pin SOIC package (PDSO8) and supports operation up to a maximum temperature of 70 °C.
Feature Summary
- Dual-channel architecture providing independent control amplifiers for precise voltage regulation
- Integrated 1.2 V precision bandgap reference source ensuring stable baseline performance
- Designed specifically for active bus termination and power rail generation on PC motherboards
Applications
- Power rail generation on personal computer motherboards
- Active bus termination circuits
- DC-DC switching controller implementations
Procurement Notes
Verify the specific suffix (e.g., JR vs. JRZ) against official Analog Devices documentation to confirm pinout compatibility and RoHS status. Confirm package type accuracy as sources vary between bulk tube and reel formats. Ensure the procurement channel provides valid traceability for this obsolete or limited-stock component.
Selection Notes
Select this component when designing systems requiring dual precision voltage regulation with integrated termination capabilities. Verify that the 12 V nominal input range aligns with the system's power supply specifications. Consider the SOIC-8 footprint constraints during PCB layout. Check current availability status as the part may be discontinued or restricted.
Part Context
The ADM1051 series belongs to Analog Devices' portfolio of power management ICs tailored for computing infrastructure. These controllers address the specific needs of high-density motherboard designs by combining regulation and termination functions into a single compact package, reducing component count and board space requirements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices technical support for qualified replacements or cross-reference options.
