AMC0236DR

ADCs/DACs - Special Purpose Overview

The AMC0236DR is a precision, basic isolated analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 16-bit resolution and utilizes a Sigma-Delta architecture to achieve a sampling rate of 3 kS/s. The device operates with an analog supply voltage range of 3 V to 5.5 V and a digital supply voltage range of 2.7 V to 5.5 V. Key performance metrics include a signal-to-noise ratio (SNR) of 89 dB and a power dissipation of 67 mW. It is housed in an SOIC-8 surface-mount package and supports operation across a temperature range of -40°C to +125°C.

ADCs/DACs - Special Purpose Feature Summary

• 16-bit resolution with Sigma-Delta modulation structure
• Basic isolation for input signal conditioning
• High accuracy with 0.99 LSB DNL and 1 LSB INL
• Low power consumption at 67 mW typical

ADCs/DACs - Special Purpose Applications

• Industrial process control systems requiring isolated measurement
• Energy metering applications for precise current/voltage sensing
• Medical equipment needing galvanic isolation
• Test and measurement instrumentation

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC-8 tape-and-reel packaging configuration. Confirm that the basic isolation rating meets the system's safety requirements, as this component provides basic rather than reinforced isolation. Ensure compatibility with the specified dual-supply voltage ranges during board design.

ADCs/DACs - Special Purpose Selection Notes

Select the AMC0236DR when a 16-bit resolution and 3 kS/s data rate are sufficient for the application. Compare against the AMC0211RDR if an isolated amplifier stage is preferred over a direct ADC solution. Verify that the 3 kV rms isolation barrier is adequate for the circuit's creepage and clearance needs.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AMC0236 series of isolated ADCs from Texas Instruments. It is designed to simplify signal chain design by integrating the isolation barrier directly into the ADC, reducing the component count compared to discrete isolator and ADC combinations.
