Low Power, High Accuracy Operational Amplifiers
|
Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, has expanded its linear product portfolio into the low power, high precision arena with the MCP6031, MCP6032, MCP6033 and MCP6034 (MCP603X) operational amplifiers (op amps). These new, sub-microampere amplifiers have a quiescent current of only 900nA and a bandwidth of 10kHz, with a maximum voltage offset of just 150µV at 25ºC. These highly accurate amplifiers are ideal for handheld, portable electronic devices used in the medical, industrial and consumer markets. |
Microchip’s low power CMOS technology and implementation
of non-volatile memory for in-package
trimming enables the MCP603X amplifiers’ extremely
low offset. This minimizes error, especially
at higher gains. Additionally, with an operating voltage
range of 1.8V to 5.5V, the amplifiers can run
off of two 1.5V battery cells under full battery utilization.
Their low power consumption extends battery
life, and their rail-to-rail input/output structure
enables greater dynamic range and better performance
across the entire operating voltage range.
As with all Microchip amplifiers, the MCP603X amplifiers
are supported by Microchip’s FilterLab® filter
design software. The FilterLab software provides
full schematic diagrams of filter circuits with component
values and displays frequency response.
