Zero-drift instrumentation amplifier provides low power, high accuracy

instrumentation amplifierMicrochip Technology Inc. (Chandler, AZ) announced the expansion of its instrumentation amplifier portfolio with the new zero-drift MCP6N16  This self-correcting architecture is positioned to DC performance by enabling ultra-low offset, low-offset drift, and desirable 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. 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, 1.8V 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 is appropriate for applications such as:

  • Sensor interfaces.
  • Signal conditioning.
  • Stationary and portable instrumentation.
