Overview
The AMC1100DUBR is a single-channel precision isolation amplifier manufactured by Texas Instruments. It features galvanic isolation with an insulation voltage of 4.25 kVrms and operates on a supply voltage range of 2.7 V to 5.5 V. The device provides a gain of 8 V/V, a 3dB bandwidth of 100 kHz, and a gain-bandwidth product of 280 kHz. Key electrical specifications include a common-mode rejection ratio (CMRR) of 108 dB, an input offset voltage (Vos) of 200 µV, and a gain error of 0.075%. It functions within a temperature range of -40°C to +105°C and is housed in an SOIC-8 package.
Feature Summary
- Provides high-performance galvanic isolation for accurate signal transmission across potential barriers.
- Delivers precise amplification with low gain error and high common-mode rejection capabilities.
- Supports differential input and output configurations for robust noise immunity.
Applications
- Isolated current sensing in motor control systems
- Voltage measurement in power monitoring applications
- Industrial process control signal conditioning
Procurement Notes
Verify the specific suffix DUBR corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets all relevant safety certification standards for the intended isolation barrier application before final integration into the design.
Selection Notes
Select this component when a single-channel isolation amplifier with a fixed gain of 8 V/V is required. It is suitable for designs needing 4.25 kVrms isolation and operation up to 105°C ambient temperature. Consider alternative packages if surface-mount constraints differ from the SOIC-8 footprint.
Part Context
This part belongs to the AMC1100 series of precision isolation amplifiers from Texas Instruments. These devices utilize capacitive isolation technology to provide high-speed, high-accuracy signal transfer while maintaining electrical isolation between input and output circuits.
Replacement Considerations
AMC1100DWVR is a verified substitute offering identical electrical characteristics but packaged in a wider SOIC-8 (DW) variant instead of the standard SOIC-8 (D).
