Original Press Release:

Simplify High-accuracy Isolated Current and Voltage Sensing

Reduce your bill of materials and design complexity with TI’s new family of high-performance isolated modulators and amplifiers with integrated high-side supply.

Eliminate discrete power supplies using an integrated DC/DC converter that generates the high-side supply internally.  This family of devices helps you lower system cost, reduce design size, increase system reliability and achieve faster design cycles with modular PCB designs.

Achieve the performance of a discrete solution. These devices offer better than 1% total accuracy, 1 GOHM of input impedance for voltage sensing, 100 kV/µs CMTI, and EMI compliance with industrial CISPR 11A/B and automotive CISPR 25 standards.

AMC3301

High accuracy for shunt-based current sensingWith offset voltage as low as ±0.1 mV and total accuracy better than 1%, this isolated amplifier enables accurate and magnetically immune current monitoring and control to achieve high-precision control loops in industrial applications.

AMC3330

Simplified isolated voltage sensing. Isolated voltage sensing no longer needs to be constrained by the availability of the high-side supply. This device can take ±1V input and offers 1 GOHM input impedance, making isolated AC and DC voltage sensing easier.

AMC3330-Q1

Streamlined automotive voltage sensing. All the benefits of the AMC3330, qualified for automotive applications.
