Microchip Technology releases the MCP6N1, its first instrumentation amplifier that is said to be ideal for applications in the consumer, industrial and medical markets, such as in signal and sensor conditioning, and instrumentation.

The instrumentation amp features the company's mCal technology, which is an on-chip calibration circuit that enables low initial offset voltage and a means to control offset drift, which results in higher accuracy across time and temperature.

The MCP6N11's low-power CMOS process technology enables low power, while offering a gain bandwidth product of 500kHz, and it features a hardware shutdown pin for even more power savings. The device's low, 1.8V operation allows two 1.5V batteries to be drained beyond typical use, and its rail-to-rail input and output operation enables full-range use, even in low-supply conditions.

Many applications in these markets require high-accuracy, low-power and low-voltage performance, and the MCP6N11 meets those needs. The device's mCal technology claims to provide a highly accurate way to minimise drift over time and temperature. Additionally, the device's low-power operation/shutdown requires less current for the given speed and performance, which extends battery life and leads to less self-heating. The MCP6N11's low-voltage operation, with rail-to-rail input and output, enables a greater dynamic range, which improves performance across the entire operating-voltage range.

The MCP6N11 instrumentation amp is supported by Microchip's MCP6N11 Wheatstone Bridge Reference Design. The MCP6N11 CMOS Instrumentation Amplifier is available in an 8-pin SOIC package and an 8-pin 2x3mm TDFN package.
