AMC1203DUB

Analog To Digital Converters (ADC) Overview

The AMC1203DUB is a 16-bit, 40 kSPS isolated delta-sigma modulator manufactured by Texas Instruments. It integrates a high-frequency sigma-delta modulator with an on-chip isolation barrier to transmit digital data across the isolation boundary. The device operates with a single 5V analog supply and supports digital supplies ranging from 1.65V to 5.5V. Key electrical specifications include a minimum power supply voltage of 4.5V for the analog section and a maximum operating temperature of 105°C. It features a low supply current of 10mA and dissipates up to 80mW under standard conditions. The component is housed in an 8-pin SOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a second-order sigma-delta modulator with a capacitive isolation barrier for signal transmission.
• Provides galvanic isolation between the analog input side and the digital output side.
• Supports differential analog inputs for improved noise rejection.
• Operates with a wide digital supply voltage range compatible with various logic families.

Analog To Digital Converters (ADC) Applications

• Isolated data acquisition systems requiring high resolution.
• Industrial process control loops with ground potential differences.
• Medical equipment requiring patient isolation barriers.
• Energy metering applications needing precise voltage or current measurement.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'DUB' corresponds to the tape-and-reel or tube packaging variant required for your assembly line. Confirm that the 8-SOP footprint matches your PCB design guidelines. Ensure the supplier provides documentation confirming RoHS compliance and the active lifecycle status as indicated in official Texas Instruments resources.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 40 kSPS data rate are sufficient for the application. Consider the 4kV isolation rating if system safety standards require it. Compare against the AMC1200 series if an analog output amplifier is preferred over a digital modulator output. Verify that the digital interface requirements align with the downstream ADC or DSP capabilities.

Analog To Digital Converters (ADC) Part Context

The AMC1203 belongs to the AMC120x family of isolated sigma-delta modulators from Texas Instruments. This family includes variants such as the AMC1200, which offers an analog output instead of a digital bitstream. The DUB suffix denotes the specific 8-pin small outline package configuration used for surface-mount assembly.

Analog To Digital Converters (ADC) Replacement Considerations

The AMC1203DUBR is the reel version of the same functional device. Other members of the AMC120x family may serve as alternatives depending on whether an analog or digital output is needed.
