AMC1203BPSAR

Analog To Digital Converters (ADC) Overview

The AMC1203BPSAR is a second-order isolated delta-sigma modulator manufactured by Texas Instruments. It features a 1-bit output with a bit rate of 10 MHz and supports sampling rates up to 40 kS/s. The device operates on dual power supplies ranging from 4.5 V to 5.5 V for both analog and digital domains. It utilizes an internal 2.5 V reference voltage and accepts differential inputs. Packaged in an 8-pin Small Outline Package (SOP), it is designed for high-precision isolation applications.

Analog To Digital Converters (ADC) Feature Summary

• Provides galvanic isolation between input and output stages using capacitive isolation technology.
• Integrates a second-order sigma-delta modulation architecture for high-resolution data conversion.
• Includes an internal precision reference voltage source to simplify external component requirements.

Analog To Digital Converters (ADC) Applications

• Isolated current shunt measurement systems
• Industrial process control signal conditioning
• Medical equipment requiring patient isolation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BPSAR' against the manufacturer's official documentation to confirm package type, temperature range, and tape-and-reel specifications. Ensure compatibility with existing board layouts regarding the SOP-8 footprint and isolation clearance requirements before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-voltage isolation is required for low-frequency, high-precision measurements. Compare performance metrics such as SNR and bandwidth against non-isolated ADCs if isolation is not strictly necessary. Consider the 40 kS/s maximum data rate to ensure it meets the system's real-time processing capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AMC1203 family of isolated delta-sigma modulators. It serves as a bridge between high-voltage analog front-ends and low-voltage digital processing units. The family is characterized by its ability to transmit data across isolation barriers while maintaining high accuracy and linearity.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include the AMC1203DWR and AMC1203DW. Verify pinout compatibility and electrical specifications before substitution. Other variants within the AMC1203 series may offer different package options or temperature ranges.
