AMC1203BDUB

Analog To Digital Converters (ADC) Overview

The AMC1203BDUB is a second-order, isolated delta-sigma modulator manufactured by Texas Instruments. It features a 1-bit output with a high-speed bitstream rate of 10 MHz and supports a data sampling rate of 40 kS/s. The device provides 16-bit resolution equivalent performance within an 8-pin SOP package. It operates on dual power supplies ranging from 4.5 V to 5.5 V for both analog and digital sections, drawing approximately 10 mA of supply current. Key electrical specifications include a signal-to-noise ratio (SNR) of 85 dB and a total power dissipation of 80 mW under typical conditions.

Analog To Digital Converters (ADC) Feature Summary

• Integrates galvanic isolation between input and output stages to protect low-side circuitry.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest datasheet revision history to confirm pinout compatibility and electrical tolerances. Ensure that the ordering documentation explicitly lists the SOP-8 package variant to avoid substitution errors with standard AMC1203 units. Cross-reference the component marking code with official factory labels during incoming inspection.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing circuits that require precise isolation barriers combined with high-speed digital output interfaces. The 10 MHz bitstream allows for flexible filtering options in subsequent digital stages. Consider thermal management requirements as the device dissipates power within a compact surface-mount footprint.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AMC1203 family of isolated data converters designed for robust industrial environments. It serves as a bridge between analog sensor signals and digital processing units while maintaining safety isolation standards. The device complements other isolation amplifiers in the TI portfolio by offering direct digital output capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

The AMC1203DUB is a standard alternative within the same family. Verify if the 'B' suffix indicates a specific binning or updated specification before swapping. Ensure that any substitute maintains the same 8-SOP physical dimensions and voltage operating ranges.
