The rapid expansion of wireless capabilities, such as Wi-Fi- and Bluetooth-enabled applications, is increasing high frequency noise in our livable space and work environments. To allow designers to provide improved performance while more easily managing an increasingly difficult environment, Microchip Technology Inc. has announced the MCP6V51 zero-drift operational amplifier. The new device provides ultra-high precision measurement while minimising the increasing influence of high frequency interference by offering a wide operating range and on-chip electromagnetic inference (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 accurate, 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 only ±36 nanovolts per degree Celsius (nV/°C) of maximum offset drift. Ideal for applications such as factory automation, process control and building automation, the MCP6V51 also supports an extremely wide operating voltage range, from 4.5V to 45V.
“Microchip is often thought of as a microcontroller company, but we have industry-leading analog to augment our total system solution for the industrial space,” said Bryan J. Liddiard, vice president of Microchip’s mixed-signal and linear business unit. “The combination of a complex chopper-stabilised architecture and a higher voltage process technology makes these devices challenging from a design and manufacturing standpoint. Microchip is a company that can do it—and do it well.”
Programmable logic controllers and distributed control systems utilised within industrial automation run on a variety of voltage rails, such as 12V, 24V, 36V. The MCP6V51 offers the flexibility to support a wide range of supply voltages and includes overhead to account for supply transients by supporting an operating range up to 45V.
Development Tools
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 easily 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.
