Introduction

MCP42010-I/ST is a series of digitally controlled potentiometers (DCP) designed to adjust various parameters such as trim and bias for electronics components. DCP applications include trimming of oscillator/resonator circuits, setting gain settings in amplifiers and setting reference voltages. The MCP42010-I/ST series is fully featured, offering a fine resolution of 1LSB and a wide variety of programming modes. In addition, it includes a wide operating temperature range and on-chip ESD protection.

Application Field

MCP42010-I/ST is suitable for a wide range of applications that require an adjustable tracking parameter or variable impedance element. To name a few, DCPs are commonly used in signal conditioning and signal processing, machine control, audio and video equipment, robotics and automation, radio communication, and consumer electronics. In each of these fields, the MCP42010-I/ST resists ESD, offering a wide range of temperature operation and fine resolution.

Working Principle

MCP42010-I/ST works by adjusting its tap or center tap resistance to control a parameter or element. These devices offer a wide operating voltage range of 1.1V to 2.5V. They feature a non-volatile tap position that is stored and maintained during power-down conditions, which gives the DCP an edge in this regard.The MCP42010-I/ST features 7-bit resolution, allowing for fine control of its resistive element. This fine resolution is achieved by a series of switches with 1LSB increments in at least 7 channels. The switches are coupled to the wiper, allowing a unique setting of the resistive element.In addition, MCP42010-I/ST includes on-chip ESD protection as well as low power consumption and low stray capacitance. It also includes a shutdown pin to save power when it is not needed.

Conclusion

MCP42010-I/ST is a series of digitally controlled potentiometers designed for use in data acquisition and other digital applications. They feature ESD protection, wide operating temperature range, and fine resolution of 1LSB. By controlling the tap or center resistance, the MCP42010-I/ST can control various parameters or elements in multiple application fields.
