New 45V, zero drift operational amplifier provides ultra-high precision plus EMI filtering
- Wide operating range and on-chip EMI minimise the influence of high-frequency interference
- Enables accurate, stable data monitoring from an increasing number of sensors
- Self-correcting zero-drift architecture offers ultra-high DC precision with low offset
- Operating voltage range from 4.5V to 45V provides overhead for supply transients
Microchip announces the MCP6V51zero-drift operational amplifier. The new device provides ultra-high precision measurement while minimising the increasing influence of high-frequency interference. The MCP6V51 offers a wide operating range and on-chip Electromagnetic Interference (EMI) filters.
The growth of industrial control and factory automation has led to an increase 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.
With the proliferation of wireless sensors and capabilities, high frequency interference within sensitive analogue measurement is becoming a critical consideration. The additional on-chip EMI filtering within the MCP6V51 provides protection from these unwanted and unpredictable interference sources. This allows designers to provide improved performance while more easily managing an increasingly difficult environment.
Programmable logic controllers and distributed control systems utilised within industrial automation run on a variety of voltage rails, such as 12V, 24V or 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.
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.
The MCP6V51 is available today for sampling and volume production in both 5-lead SOT-23 and 8-lead MSOP packages.
