New 45V, Zero-drift Operational Amplifier Provides Ultra-high Precision Plus EMI Filtering
January 15 2019 - 8:00AM
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.
(Nasdaq: MCHP) today announced the
MCP6V51
zero-drift operational amplifier. The new device provides
ultra-high-precision measurement while minimizing the increasing
influence of high-frequency interference by offering a wide
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 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 analog measurement is
becoming a critical consideration. The additional on-chip EMI
filtering within the MCP6V51 provides protection from these
unwanted and unpredictable interference sources.
“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-stabilized 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
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 wide range of supply voltages and includes overhead to
account for supply transients by supporting an operating range up
to 45V.
Development ToolsFor 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.
Pricing and AvailabilityThe MCP6V51 is
available today for sampling and volume production in both 5-lead
SOT-23 and 8-lead MSOP packages. Prices begin at $0.98 USD per
10,000 units for the SOT-23-5 package.
