AMC1300BDWVR

Overview

The AMC1300BDWVR is a precision isolated amplifier from Texas Instruments designed for high-accuracy current sensing applications. It features a ±250-mV input range and an 8.2 V/V gain. The device provides reinforced galvanic isolation with a 5000 Vrms insulation voltage, ensuring safety in high-voltage environments. Key electrical specifications include a 310 kHz 3dB bandwidth, 100 dB common-mode rejection ratio (CMRR), and low offset voltage of 200 µV. It operates on a single supply voltage between 3 V and 5.5 V, consuming approximately 6.3 mA of quiescent current. The component is housed in an SOIC-8 package and supports extended industrial temperature ranges.

Feature Summary

• Reinforced galvanic isolation barrier certified for high-voltage safety standards
• Precision signal amplification with low offset voltage and drift characteristics
• High common-mode rejection capability to suppress noise in noisy environments
• Differential output configuration compatible with standard ADC interfaces

Applications

• Current sensing in motor drives and inverters
• Power supply feedback loops
• Industrial process control systems
• Energy metering equipment

Procurement Notes

Verify the specific suffix 'B' against the official datasheet to confirm it denotes the correct revision or variant within the AMC1300 family. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Confirm that the 5000 Vrms isolation rating meets the safety clearance and creepage distances required by your target application's regulatory standards. Check humidity sensitivity levels for proper storage and handling procedures during assembly.

Selection Notes

Select this component when reinforced isolation is mandatory rather than basic isolation. The 310 kHz bandwidth suits most motor control and power conversion frequencies. Compare the 200 µV offset voltage against other variants if ultra-high precision is needed. Consider the 6.3 mA supply current for battery-operated or power-sensitive designs. Ensure the ±250 mV input range aligns with the shunt resistor voltage drop in your circuit.

Part Context

This part belongs to the AMC1300 series of precision isolated amplifiers. It shares architectural similarities with the AMC1300DWVR but may differ in specific performance parameters or qualification status. The series is designed to replace traditional transformer-based isolation solutions in modern digital power systems.

Replacement Considerations

AMC1300DWVR is a related variant within the same series. Verify if the DWVR version meets the specific isolation and accuracy requirements before substitution.
