June 13, 2019 by Mouser Electronics

Microchip Technology High-Side Current Sense Amplifiers provide input offset voltage correction for very low offset.

This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

Microchip Technology High-Side Current Sense Amplifiers

Microchip Technology’s MCP6C04 is a High-Side Current Sense Amplifier with a zero-drift architecture minimizing input errors and enables the use of lower value shunt resistors for lower power dissipation.  

The MCP6C04 supports unidirectional and bidirectional applications, specified for 3 to 52-volt inputs. The amplifier’s architecture makes it ideal for use in noisy environments. It provides very low input offset voltage and gain error as well as a high common mode rejection ratio and power supply rejection ratio, including higher rejection ratios at high frequencies.  

Amplifiers are available with preset gains of 20, 50, or 100 volts per volt, and have a typical bandwidth of 500 kilohertz. The MCP6C04 operates from a 2.0 to 5.5 volt supply and includes power-on reset and EMI protections to reduce design complexity.
