AMC1302DWVR

Overview

The AMC1302DWVR is a precision isolated amplifier manufactured by Texas Instruments, designed for high-voltage current and voltage sensing applications. It features a ±50-mV input range with a fixed gain of 8.2 V/V. The device provides galvanic isolation with an insulation voltage of 5000 Vrms and a common-mode rejection ratio (CMRR) of 100 dB. It operates on a single supply voltage ranging from 4.5 V to 5.5 V, consuming typical supply currents of 5.9 mA and 7.2 mA. The component is housed in an 8-SOIC package and supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for accurate measurement of high-side or low-side currents and voltages in noisy environments.
• Delivers high precision with low input offset voltage and low gain error for reliable signal integrity.
• Features reinforced insulation capabilities suitable for demanding industrial and power management systems.

Applications

• Current sensing in motor drives and inverters
• Power supply monitoring and control circuits
• Industrial automation and process control systems

Procurement Notes

Verify the specific suffix 'DWVR' corresponds to the SOIC-8 package and tape-and-reel packaging configuration. Confirm that the required insulation ratings and input voltage range align with the system's isolation requirements. Ensure compatibility with the 4.5 V to 5.5 V supply voltage domain. Check for any recent product change notices regarding assembly materials or manufacturing sites.

Selection Notes

Select this component when a fixed gain of 8.2 V/V and a ±50-mV input window are required. It is suitable for designs needing 5000 Vrms isolation without external transformers. Consider alternatives if higher bandwidth or different gain settings are necessary. Verify that the 8-SOIC footprint fits the PCB layout constraints.

Part Context

This part belongs to the AMC130x family of isolated amplifiers from Texas Instruments. These devices utilize capacitive isolation technology to provide high CMRR and bandwidth. The family includes variants with different input ranges and gains, such as the AMC1300 and AMC1301, offering flexibility for various sensing topologies.

Replacement Considerations

Check for direct pin-compatible substitutes within the AMC130x series, such as the AMC1300DWVR or AMC1301DWVR, noting differences in input range and gain. Verify functional equivalence before substitution.
