AMC1301QDWVQ1

Overview

The AMC1301QDWVQ1 is a precision isolated amplifier from the AMC1301 series, designed for automotive applications with AEC-Q100 qualification. It features galvanic isolation with an insulation voltage of 5000 Vrms and supports differential or single-ended inputs. Key electrical parameters include a gain-bandwidth product of 1 MHz, a 3dB bandwidth of 210 kHz, and a common-mode rejection ratio (CMRR) of 92 dB. The device operates on a supply voltage between 3 V and 5.5 V, drawing 5.9 mA. Input specifications include a bias voltage of 50 uV and input bias current of -60 uA. Gain error is specified at 0.03%, with a maximum output current of 13 mA per channel.

Feature Summary

• Provides galvanic isolation with reinforced insulation capabilities suitable for high-voltage environments
• Delivers precision signal amplification with low input offset voltage and minimal gain error
• Supports flexible input configurations including both differential and single-ended modes

Applications

• Automotive current sensing using shunt resistors
• Power management systems requiring isolated feedback
• Motor control applications involving precise current measurement

Procurement Notes

Verify the specific suffix Q1 confirms automotive grade AEC-Q100 qualification. Confirm package type SOIC-8 matches design requirements. Check humidity sensitivity level for storage and handling protocols. Ensure supply voltage range aligns with system power rails. Validate isolation voltage ratings against circuit safety standards.

Selection Notes

Select this component when high precision and automotive reliability are required. Compare CMRR and bandwidth against noise environment needs. Evaluate supply current consumption for power-sensitive designs. Consider input configuration flexibility for existing schematic constraints. Verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the AMC1301 family of precision isolated amplifiers by Texas Instruments. It shares core specifications with non-automotive variants like the AMC1301DWVR but includes automotive-specific qualification. The family focuses on providing accurate isolation in compact SOIC-8 packages for industrial and automotive use cases.

Replacement Considerations

AMC1301DWVRQ1 serves as a reel/cut-tape alternative within the same automotive qualification. Non-automotive AMC1301DWVR may be considered if AEC-Q100 certification is not mandatory.
