AMC1203DUBR

Analog To Digital Converters (ADC) Overview

The AMC1203DUBR is a 16-bit, 40 kS/s isolated delta-sigma modulator manufactured by Texas Instruments. It integrates a second-order sigma-delta modulator with digital isolation technology to provide galvanic isolation between analog input and digital output domains. The device operates on a single 5V supply for both analog and digital sections, consuming approximately 80 mW of power. It features an internal 2.5V reference voltage and accepts differential inputs. The component is housed in an 8-pin SOP package and supports serial data interfaces. It is designed for high-accuracy applications requiring robust noise immunity and precise signal conditioning across isolation barriers.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix DUBR confirms the tape-and-reel packaging format when sourcing components. Ensure that the procurement documentation explicitly lists the manufacturer as Texas Instruments to avoid counterfeit parts. Cross-reference the part number against official distributor catalogs to confirm active status and compliance with RoHS standards before finalizing orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing circuits that require high-resolution data acquisition across isolation barriers without external references. Consider the 40 kS/s sampling rate and 16-bit resolution against system bandwidth requirements. Evaluate the 80 mW power consumption relative to thermal constraints within the SOP-8 package. Confirm compatibility with the target microcontroller's serial interface timing specifications.

Analog To Digital Converters (ADC) Part Context

The AMC1203 belongs to Texas Instruments' family of isolated delta-sigma modulators, which combine analog front-end processing with digital isolation. This series is engineered for applications where traditional isolation amplifiers lack sufficient resolution or bandwidth. The DUBR variant specifically denotes the surface-mount SOP-8 package configuration optimized for automated assembly processes in compact electronic designs.

Analog To Digital Converters (ADC) Replacement Considerations

The AMC1203DW serves as a pin-compatible alternative offering the same functional specifications in a SOIC-16 package. Designers requiring different footprint dimensions may consider this option while maintaining identical electrical performance characteristics and isolation capabilities.
