AMC1301QDWVRQ1

Overview

The AMC1301QDWVRQ1 is a precision isolated amplifier from the AMC1301 series, designed for automotive applications. It features galvanic isolation with an insulation voltage of 5000 Vrms and operates within a supply voltage range of 3 V to 5.5 V. The device offers a gain-bandwidth product of 1 MHz and a 3dB bandwidth of 210 kHz. Key electrical specifications include a common-mode rejection ratio (CMRR) of 92 dB, an input bias current of -60 uA, and an input offset voltage of 50 uV. It consumes 5.9 mA of operating power and supports differential or single-ended inputs. The component is qualified under AEC-Q100 standards and functions reliably between -40°C and +125°C.

Feature Summary

• Provides galvanic isolation with high insulation voltage capability for robust signal integrity in noisy environments.
• Delivers precision performance with low input offset voltage and high common-mode rejection ratio.
• Supports flexible input configurations including both differential and single-ended modes.

Applications

• Automotive current sensing
• Power management systems
• Motor control circuits

Procurement Notes

Verify the specific suffix 'Q1' confirms automotive qualification status against official Texas Instruments documentation. Confirm the 'RQ1' designation indicates reel packaging rather than tube. Ensure compatibility with required humidity sensitivity levels and surface mount technology requirements before finalizing procurement orders.

Selection Notes

Select this component when high-precision isolation is required for automotive-grade current sensing or power monitoring. The 5000 Vrms isolation rating suits applications demanding significant noise immunity. Consider the 210 kHz bandwidth and 1 MHz gain-bandwidth product for dynamic signal requirements. Verify that the SOIC-8 package fits the available board space constraints.

Part Context

This part belongs to the AMC1301 family of precision isolated amplifiers manufactured by Texas Instruments. It shares core architectural similarities with other members like the AMC1301QDWVQ1, differing primarily in packaging format and specific automotive qualification markings. The series is engineered for high-reliability industrial and automotive electronics requiring accurate analog signal transmission across isolation barriers.

Replacement Considerations

The AMC1301QDWVQ1 serves as a direct functional alternative, offering identical electrical characteristics but utilizing tube packaging instead of reel or cut tape formats. Designers must verify that the change in physical packaging does not impact automated assembly processes or storage handling procedures.
