Microchip’s low-power, high-accuracy instrumentation amplifier offers on-chip calibration for enhanced performance

by donpedro

Key Facts:
• Microchip’s first instrumentation amplifier
• mCal on-chip calibration technology enables higher accuracy across time and temperature
• 1.8V operation extends battery life and enables full-range use even in low-supply conditions
• Combines high performance and a competitive price-point for consumer, industrial and medical applications
Microchip announces its first instrumentation amplifier, the MCP6N11. The new instrumentation amp features Microchip’s unique mCal technology, which is an on-chip calibration circuit that enables low initial offset voltage and a means of controlling offset drift, resulting in higher accuracy across time and temperature. The MCP6N11’s low-power CMOS process technology enables low power, whilst providing a gain bandwidth product of 500 kHz, and a hardware shutdown pin for even greater power savings. The device’s low, 1.8V operation allows two 1.5V batteries to be drained beyond typical use, whilst its
rail-to-rail input and output operation enables full-range use, even in low-supply conditions. The MCP6N11 is an innovative solution for instrumentation, signal and sensor conditioning in consumer, industrial and medical applications which require a combination of high performance at a competitive price-point.
Many applications in these markets require high-accuracy, low-power and low-voltage performance which can be achieved with the MCP6N11. The device’s mCal technology provides a highly accurate way to minimise drift over time and temperature, whilst the low-power operation/shutdown requires less current for the given speed and performance, extending battery life, and leading to less self-heating. The MCP6N11’s low-voltage operation, with rail-to-rail input and output, enables a greater dynamic range, to improve performance across the entire operating-voltage range.
The MCP6N11 is offered in 8-pin SOIC and 2mm x 3mm TDFN package options. Development of the MCP6N11 instrumentation amp is supported by Microchip’s MCP6N11 Wheatstone Bridge Reference Design (ARD00354), priced at $ 34.99.
