January 15, 2019 — Microchip Technology announced the MCP6V51 zero-drift operational amplifier. The device provides precision measurement while minimizing the increasing influence of high-frequency interference by offering an operating range and on-chip electromagnetic interference (EMI) filters.
The growth of industrial control and factory automation has led to an uptick in the number of sensors that need to be monitored, and the MCP6V51 amplifier is designed to provide stable data from a variety of sensors. The self-correcting zero-drift architecture of the MCP6V51 enables ultra-high Direct Current (DC) precision, providing a maximum offset of ±15 microvolts (µV) and ±36 nanovolts per degree Celsius (nV/°C) of maximum offset drift. Designed for applications such as factory automation, process control and building automation, the MCP6V51 also supports an operating voltage range, from 4.5V to 45V.
With the proliferation of wireless sensors and capabilities, high-frequency interference within sensitive analog measurement is becoming a critical consideration. The additional on-chip EMI filtering within the MCP6V51 provides protection from these unpredictable interference sources.
Programmable logic controllers and distributed control systems utilized within industrial automation run on a variety of voltage rails, such as 12V, 24V and 36V. The MCP6V51 offers the flexibility to support a range of supply voltages and includes overhead to account for supply transients by supporting an operating range up to 45V.
For evaluation, the 8-Pin SOIC/MSOP/TSSOP/DIP Evaluation Board (Part # SOIC8EV) is a blank PCB that allows the operation of Microchip Technology’s 8-pin devices to be evaluated. Each device pin is connected to a pull-up resistor, a pull-down resistor, an in-line resistor, and a loading capacitor. The PCB pads allow through-hole or surface mount connectors to be installed to ease connection to the board. Additional passive component footprints are on the board to allow simple circuits to be implemented.
