Zero-Drift Instrumentation Amplifier Provides Low Power, High Accuracy

Microchip Technology Inc. announced the expansion of its instrumentation amplifier portfolio with the new zero-drift MCP6N16.  This self-correcting architecture maximizes 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.  The result is very high accuracy across both time and temperature.

The MCP6N16's low-power CMOS process technology enables low power consumption while still providing 500 kHz bandwidth, and it features a hardware-enable pin for even more power savings.  This low-power operation and shutdown capability requires less current for the given speed and performance, which extends battery life and leads to less self heating.  Additionally, the amplifier's low, 1.8 V operation allows two dry-cell, 1.5 V batteries to be drained well beyond typical use, and its rail-to-rail input and output operation enables full-range use, even in low-supply conditions.  This provides better performance across the entire operating-voltage range.

The MCP6N16 instrumentation amp is ideal for applications that require a combination of high performance and precision, low power consumption, and low-voltage operation.  Examples include sensor interfaces, signal conditioning, and stationary and portable instrumentation, for the medical, consumer and industrial markets.

The Zero-Drift MCP6N16 Instrumentation Amplifier is available today for samples and volume production, in 8-pin MSOP and 3x3 mm DFN packages.  Both package options are priced at $1.52 each in 5,000-unit quantities.
