AMC1203PSAR

Analog To Digital Converters (ADC) Overview

The AMC1203PSAR is a second-order isolated delta-sigma modulator manufactured by Texas Instruments. It features a 1-bit output with a high-speed data rate of 10 MHz, designed for precision current-shunt measurement applications. The device operates on a single 5 V supply and provides galvanic isolation between the analog input and digital output stages. Packaged in an 8-pin SOIC (PSAR) surface-mount format, it supports differential inputs and integrates internal filtering to achieve high resolution when paired with external decimation logic.

Analog To Digital Converters (ADC) Feature Summary

• Provides galvanic isolation for safe signal transmission in high-voltage environments
• Utilizes second-order sigma-delta architecture for enhanced noise performance
• Supports differential input configurations for accurate shunt sensing

Analog To Digital Converters (ADC) Applications

• Current-shunt measurement in industrial motor drives
• Isolated signal conditioning for power monitoring systems
• High-voltage sensor interface circuits

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix PSAR corresponds to the tape-and-reel packaging variant during sourcing. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the supplier provides valid traceability documentation as this is a specialized isolation component.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed 10 MHz modulation is required for downstream digital filtering. Compare against non-isolated ADCs if system ground loops are not a concern. Ensure the external microcontroller or FPGA can handle the 10 MHz bitstream processing load effectively.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AMC1203 family of isolated modulators from Texas Instruments. It shares architectural similarities with other devices in the series but is distinguished by its specific package type and speed characteristics. It serves as a bridge between low-voltage control logic and high-voltage power stages.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include the AMC1203DUBR for SOP-8 reel packaging or the AMC1203BPSA for tube packaging variants within the same functional family.
