AMC1304M25DWR

ADCs/DACs - Special Purpose Overview

The AMC1304M25DWR is a precision isolated delta-sigma modulator manufactured by Texas Instruments. It features an analog input range of ±250 mV and provides galvanic isolation between the input and output stages. The device utilizes a CMOS digital interface for data transmission, operating with a single supply voltage ranging from 3 V to 5.5 V on both sides. It is housed in a 16-pin SOIC package (DW) and supports industrial temperature ranges from -40°C to +125°C. This component functions as a high-resolution analog-to-digital front-end, converting analog signals into a bitstream for subsequent processing.

ADCs/DACs - Special Purpose Feature Summary

• Precision ±250-mV input range suitable for shunt-based current sensing applications
• Galvanic isolation barrier providing safety and noise immunity
• CMOS-compatible digital output interface for direct connection to DSPs or FPGAs
• Low power consumption with operation supported by 3-V to 5.5-V supplies

ADCs/DACs - Special Purpose Applications

• High-side current sensing in motor drives and inverters
• Power supply monitoring and control systems
• Industrial automation and process control instrumentation
• Energy metering and smart grid infrastructure

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the design requires a delta-sigma modulator architecture rather than a complete ADC with integrated decimation filters. Ensure the isolation voltage ratings meet the system's safety requirements. Check for RoHS compliance status if environmental regulations apply to the deployment region.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a high-resolution analog front-end with built-in isolation is required. The ±250-mV input range dictates the need for external shunt resistors or signal conditioning circuits to scale the measured current or voltage appropriately. Compare performance metrics such as bandwidth and noise density against other AMC130x family members if different input ranges or interface types are needed.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AMC130x family of isolated modulators from Texas Instruments. It shares architectural similarities with parts like the AMC1304M25QDWQ1, though the latter carries automotive qualification suffixes. The standard commercial grade variant lacks the specific reliability certifications associated with automotive-grade counterparts within the same functional family.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements include other variants within the AMC1304 series, such as AMC1304M25DGVR, depending on the required package type. For automotive applications, the AMC1304M25QDWQ1 serves as the qualified alternative. Verify pinout compatibility and electrical specifications before substituting with non-TI isolated modulators.
