AMC1303E2510DWV

ADCs/DACs - Special Purpose Overview

The AMC1303E2510DWV is a precision isolated sigma-delta modulator manufactured by Texas Instruments. It features a reinforced capacitive isolation barrier rated for high voltage applications. The device provides 16-bit resolution with a maximum sampling rate of 78 kSPS and supports a clock frequency up to 10 MHz. It operates on dual power supplies ranging from 2.7 V to 5.5 V for digital domains and 3.3 V to 5 V for analog domains. Key performance metrics include a gain error of 0.2%, integral nonlinearity (INL) of 4 LSB, and differential nonlinearity (DNL) of 0.99 LSB. The component is housed in an 8-pin SOIC package and functions within a temperature range of -40°C to +125°C.

ADCs/DACs - Special Purpose Feature Summary

• Reinforced capacitive isolation barrier for safety-critical applications
• 16-bit resolution with 78 kSPS maximum data rate
• Low DNL (0.99 LSB) and INL (4 LSB) for high accuracy
• Wide operating temperature range from -40°C to +125°C

ADCs/DACs - Special Purpose Applications

• Current sensing in motor drives and inverters
• Precision current measurement in industrial automation
• Isolated signal conditioning for energy metering systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the suffix 'DWV' indicates a tube packaging option, distinct from the 'DWVR' reel variant. Confirm insulation voltage ratings and RoHS compliance status against the latest manufacturer datasheet before procurement. Ensure ESD handling protocols are followed due to moisture sensitivity level 3 classification.

ADCs/DACs - Special Purpose Selection Notes

Select this model when a fixed gain of 10 V/V is required for isolated current sensing. Compare against the AMC1303E2520DWV if a gain of 20 V/V is needed instead. Ensure the system design accommodates the separate analog and digital supply voltage requirements and the external clock input necessary for sigma-delta modulation.

ADCs/DACs - Special Purpose Part Context

This component belongs to the AMC1303x family of isolated delta-sigma modulators. It shares the same core architecture and isolation technology as variants like the AMC1303E2520DWV but differs in specified gain settings. The family is designed to interface directly with ADCs or microcontrollers in high-noise environments.

ADCs/DACs - Special Purpose Replacement Considerations

The AMC1303E2520DWV is a functional substitute within the same series, offering identical isolation and resolution but with a different gain specification (20 V/V vs 10 V/V). Verify circuit compatibility regarding gain scaling before substitution.
