AMC1100DUB Isolated Precision Delta-Sigma Modulator from Texas Instruments

The AMC1100DUB from Texas Instruments is a precision isolation amplifier with an output separated from the input circuitry by a silicon dioxide (SiO₂) barrier that is highly resistant to magnetic interference. This isolation barrier has been certified to provide galvanic isolation of up to 4000 V_PEAK according to UL1577 and CSA standards.

This component is designed for use in current shunt measurement and other applications where an accurate signal is required to be transmitted across a galvanic isolation barrier. It utilizes a delta-sigma modulator with a 1-bit data stream output. The combination of the modulator and external digital filter (not included) allows for precise, high-resolution signal conversion.

The AMC1100DUB operates over a wide supply range of ±2.25V to ±18V and features a full-scale input range of ±250 mV, making it versatile for various applications. Its compact footprint in a 8-pin SOIC package makes it ideal for space-constrained applications while ensuring a low power consumption of 19.5 mW at 5V.

Key features of the AMC1100DUB include:

• High Electromagnetic Immunity
• Fail-Safe Output
• Low Offset Error
• Low Nonlinearity: 0.01%
• Low Noise
• Extended Industrial Temperature Range: –40°C to +125°C

Applications for AMC1100DUB are diverse and include motor control, power management systems, green energy applications, and industrial process control. Its reliability and performance are suitable for professional environments where precision and durability are paramount.
