A new instrumentation amplifier has been developed by Microchip with on-chip calibration for enhanced performance.
The new instrumentation amp features the company’s mCal technology, which is an on-chip calibration circuit that enables low initial offset voltage and a means of controlling offset drift.
This results 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 500kHz, and a hardware shutdown pin for even greater power savings.
A low, 1.8V operation allows two 1.5V batteries to be drained beyond typical use, whilst it’s rail-to-rail input and output operation enables full-range use, even in low-supply conditions.
The device is aimed at instrumentation, signal and sensor conditioning in consumer, industrial and medical applications.
Many applications in these markets require high-accuracy, low-power and low-voltage performance, which can be achieved with the solution.
The technology is an accurate way to minimise drift over time and temperature, whilst the low-power operation/shutdown requires less current for the given speed and performance. This in effect extends the battery life.
