AMC1301DWVR

Overview

The AMC1301DWVR is a precision isolated amplifier manufactured by Texas Instruments, housed in an 8-SOIC package. It features a fixed gain of 8.2 V/V and supports a supply voltage range of 3 V to 5.5 V with a typical operating current of 5 mA. The device provides galvanic isolation with a reinforced insulation rating of 5 kVrms. Key electrical specifications include a 1 MHz gain-bandwidth product, a 3-dB bandwidth of 210 kHz, and a common-mode rejection ratio of 93 dB. Input characteristics specify a bias current of 60 µA and an offset voltage of 50 µV. The output stage delivers up to 13 mA per channel with differential output capability.

Feature Summary

• Provides reinforced galvanic isolation for high-voltage signal transmission
• Delivers precision amplification with low input offset voltage and bias current
• Features a wide common-mode rejection ratio for noise immunity
• Supports differential output configuration for robust signal integrity

Applications

• Current sensing in motor drives and power inverters
• Isolated measurement in industrial process control systems
• Energy metering applications requiring precise voltage or current acquisition
• Grid-tied inverter feedback loops

Procurement Notes

Verify the specific suffix 'DWVR' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the required insulation clearance and creepage distances meet the safety standards of the final equipment design. Ensure the operating temperature range of -40°C to 125°C aligns with the environmental conditions of the target application. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a fixed gain of 8.2 V/V is suitable for the input signal range. Consider the 5 kVrms isolation rating for safety requirements. Evaluate the 210 kHz bandwidth against the maximum signal frequency to ensure adequate response time. Compare the 5 mA supply current against system power constraints relative to other isolator families.

Part Context

This device belongs to the AMC130x family of high-voltage isolation amplifiers from Texas Instruments. It utilizes capacitive isolation technology to achieve signal transfer across the isolation barrier. The DWVR suffix indicates surface-mount packaging in a tape-and-reel format, facilitating automated assembly processes in high-volume manufacturing environments.

Replacement Considerations

The AMC1301DWVRG4 is a lead-free version of the same functional device. Verify pinout compatibility and thermal performance before substitution.
