AMC1306M25DWVR

ADCs/DACs - Special Purpose Overview

The AMC1306M25DWVR is a precision isolated sigma-delta modulator manufactured by Texas Instruments. It features a ±250-mV input range and provides galvanic isolation for high-voltage current sensing applications. The device operates on a single supply voltage ranging from 3.3 V to 5 V and delivers a 16-bit resolution with a sampling rate of 78 kS/s. Key electrical specifications include a differential nonlinearity (DNL) of 0.99 LSB, an integral nonlinearity (INL) of 4 LSB, and a gain error of 0.2%. It dissipates 87 mW of power and functions within a temperature range of -40°C to +125°C in an 8-pin SOIC package.

ADCs/DACs - Special Purpose Feature Summary

• Isolated Sigma-Delta Modulator with ±250-mV input range
• 16-bit resolution at 78 kS/s sampling rate
• Low DNL (0.99 LSB) and INL (4 LSB)
• Operates on 3.3 V to 5 V supply

ADCs/DACs - Special Purpose Applications

• High-voltage and high-current sensing in motor drives
• Power inversion systems
• Switched-mode power supplies (SMPS)

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DWVR' against the manufacturer's official datasheet to confirm pinout compatibility and packaging details. Ensure that the required isolation voltage ratings meet the system design requirements before procurement. Cross-reference the component marking with the official TI part identification guide to prevent counterfeit components.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 16-bit resolution and 78 kS/s data rate are sufficient for the application. The ±250-mV input range dictates the need for an external shunt resistor or current transformer. Compare power dissipation of 87 mW against thermal constraints in the SOIC-8 package. Verify that the serial CMOS interface matches the microcontroller or DSP capabilities.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AMC1306 family of isolated modulators. It shares the same core architecture as the automotive-grade AMC1306M25QDWVRQ1 but lacks the Q1 suffix indicating AEC-Q100 qualification. It is distinct from the AMC1306M05DWVR, which supports a wider 2.7 V to 5.5 V supply range. The DWVR suffix denotes the 8-SOIC package with tape-and-reel shipping.

ADCs/DACs - Special Purpose Replacement Considerations

The AMC1306M25QDWVRQ1 is a qualified alternative offering identical electrical performance with automotive reliability standards. For applications requiring a wider supply voltage range, the AMC1306M05DWVR is a compatible substitute.
