Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced it 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). The new, sub-microampere amplifiers have a quiescent current of only 900 nA and a bandwidth of 10 kHz, with a maximum voltage offset of just 150 µV at 25 degrees Celsius. The 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.
“Microchip continues to leverage its low-power, CMOS technology to provide another family of industry-leading op amps,” said Bryan Liddiard, vice president of Microchip’s Analog and Interface Products Division. “The MCP603X devices lead the industry with their combination of low power consumption and low-offset performance, and are expected to enable new markets for Microchip in portable instrumentation.”
The MCP603X devices are well suited for applications requiring low power consumption, low-voltage operation and high precision, such as portable instrumentation devices used in the industrial (portable gas detectors, pressure-monitoring devices, toll-booth tags, digital multimeters, RFID readers, bar-code scanners); medical (blood glucose meters, wearable heart-rate monitors and body-temperature measurement sensors); and consumer (gaming consoles, set-top boxes and portable audio players) markets.
As with all Microchip amplifiers, the MCP603X amplifiers are supported by Microchip’s FilterLab(R) filter-design software, which simplifies active-filter design. The FilterLab software provides full schematic diagrams of filter circuits with component values, and displays frequency response.
