AMC1203DW

Analog To Digital Converters (ADC) Overview

The AMC1203DW is a 16-bit resolution analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a second-order sigma-delta modulation architecture with an internal reference and operates on a single 4.5 V to 5.5 V supply for both analog and digital domains. The device features a differential input, serial interface, and supports a maximum sampling rate of 40 kS/s. Housed in a 16-pin SOIC package, it functions within a temperature range of -40°C to +105°C. Key performance metrics include a signal-to-noise ratio of 85 dB, spurious-free dynamic range of 95 dB, and power consumption of 80 mW.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a precision delta-sigma modulator with an internal voltage reference to simplify system design.
• Provides high common-mode rejection and low noise performance suitable for isolated measurement applications.
• Features a serial interface compatible with standard microcontroller communication protocols.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise current or voltage sensing.
• Medical equipment utilizing galvanic isolation for patient safety.
• Energy metering applications demanding high linearity and accuracy.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-16 tube packaging when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly timeline. Ensure the supplier provides valid traceability documentation for automotive or medical certifications if applicable to your end-use environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 40 kS/s data rate are required in a compact surface-mount package. Compare against the AMC1203DUBR variant if tape-and-reel packaging is preferred for automated assembly. Evaluate the trade-off between the higher bandwidth of SAR ADCs versus the superior DC accuracy of this sigma-delta architecture.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AMC1203 family of isolated delta-sigma modulators from Texas Instruments. It shares architectural similarities with other members like the AMC1200 but differs in resolution and output type. The DW suffix specifically denotes the 16-lead Small Outline Integrated Circuit package, distinguishing it from the 8-lead SOP variants in the same series.

Analog To Digital Converters (ADC) Replacement Considerations

The AMC1203DWVR is a pin-compatible alternative available in tape-and-reel packaging. Verify that any substitute maintains the same 16-bit resolution, 40 kS/s speed, and SOIC-16 footprint to ensure mechanical and electrical compatibility without redesigning the PCB layout.
