Expanding its instrumentation amplifier portfolio, Microchip Technology has introduced the MCP6N16. This zero-drift device features a self-correcting architecture which maximises DC performance by enabling ultra-low offset, low offset drift, and superior common-mode and power-supply rejection, while eliminating the adverse effects of 1/f noise.

This enables the MCP6N16 instrumentation amplifier to provide very high accuracy across both time and temperature. It is suitable for use in applications requiring high performance, precision, low power consumption and low-voltage operation, such as sensor interfaces, signal conditioning, and stationary and portable instrumentation, for the medical, consumer and industrial markets.

Low-power CMOS process technology enables the MCP6N16 to deliver low power consumption whilst still providing 500kHz bandwidth. A hardware-enable pin allows for even more power savings. The low-power operation and shutdown capability requires less current for the given speed and performance, extending battery life and preventing self-heating.

The amplifier’s low, 1.8V operation allows two dry-cell, 1.5V batteries to be drained well beyond typical use. Its rail-to-rail input and output operation enables full-range use, even in low-supply conditions, providing better performance across the entire operating-voltage range.

Supplied in in 8-pin MSOP and 3x3mm DFN packages, the zero-drift MCP6N16 instrumentation amplifier is sampling and in volume production now.
