The FilterLab tool simplifies active filter design and gives users full schematic diagrams of the filter circuit with component values and displays the frequency response, all of which make designing variable filters utilizing op amps easier.
The op amps are also supported by Microchip's Active Filter Demo Board Kit (part # MCP6XXXDM-FLTR, $65.
Microchip has again leveraged its low-power, CMOS technology to provide additional families of industry-leading op amps, with the MCP605X/6X/7X devices," said Bryan Liddiard, vice president of Microchip's Analog and Interface Products Division.

For this application, the appropriate choice is an op amp with slew rates at least equal to the rise time of the digital signal and a bandwidth two to three times at least that of the incoming signal.
Microchip's low-power, high-bandwidth op amps, with availability in small packages and extended temperature range operation capabilities, have developed a reputation for standing above the competition for a wide range of customer applications," said Rich Simoncic, vice president of Microchip's Analog and Interface Products Division.
5V and low typical quiescent current of just 300 microamperes (oA), the MCP6V0X op amps can run off two 1.
So, bandwidth and slew rate having been established, designers can find a significant number of viable op amps from major manufacturers that will meet the requirements.
The new amplifiers can be used as drop-in replacements for op amps, as microcontroller-controlled amplifiers or as stand-alone gain blocks and eliminate the need for external resistors.
In addition, the op amp is available in a tiny standard surface mount package to meet the size requirements of space-constrained battery-powered applications and is priced to meet the needs of high-volume markets.
JFET-input operational amplifier and voltage references: The new JFET (junction field effect transistor)-input op amp (operational amplifier) and a new family of voltage references have been optimized to provide designers of industrial and instrumentation systems extremely high-precision performance, ultra small size and very low power consumption, saving board space and improving circuit layout flexibility at a cost lower than competing devices.
