Microchip Technology Australia , a provider of microcontroller and analogue semiconductors, has announced the MCP6V01/2/3 (MCP6V0X) auto-zero operational amplifiers (op amps).

The low-power op amps feature a self-correcting architecture that enables high precision, with an input offset voltage of 2 micro Volts (µV) maximum.

The MCP6V01/2/3 (MCP6V0X) auto-zero operational amplifiers also feature high common-mode rejection, rail-to-rail input/output and low quiescent current; making them suitable for portable, battery-powered instrumentation devices, such as those used in the industrial and medical markets.

With their low operating-voltage range of 1.8V to 5.5V and low typical quiescent current of 300 microamperes (µA), the MCP6V0X op amps can run off two 1.5V cells with full battery utilisation.

The devices feature a self-correcting architecture that results in fewer errors, especially at higher gains. Additionally, their rail-to-rail input/output structure enables high dynamic range. The combined result of these features is better system performance at all operating voltages.

"Microchip continues to leverage its low-power CMOS technology to provide yet another industry-leading op amp family," said Bryan Liddiard, Vice President of Marketing with Microchip Technology Australia's Analog and Interface Products Division.

"The MCP6V0X amplifiers extend our op amp portfolio into the ultra high-precision marketplace, and provide critical intellectual property for continued growth in this area."

Kevin Tretter, Senior Product Marketing Engineer with Microchip Technology Australia's Analog and Interface Products Division, continued, "The MCP6V0X op amps' extremely low offset and rail-to-rail performance provide tremendous flexibility, with regard to gain control and dynamic range. We expect these devices to enable new markets in instrumentation."

Applications requiring low power consumption, low-voltage operation, high precision and low drift can benefit from the performance and features offered by the MCP6V0X op amps.

Examples include battery-powered devices and instrumentation used in medical applications (e.g. sensor calibration for defibrillators and CT scanners); as well as industrial applications (e.g. high-precision temperature sensing and DC offset correction).

Development Support

Like all Microchip Technology Australia’s op amps, the MCP6V0X family is supported by the FilterLab Analog Filtering Software Tool and the Mindi Online Simulator Tool.

Available from Microchip Technology Australia's website, the FilterLab analogue filtering software tool provides full schematic diagrams of the filter circuit with component values, and displays the frequency responses.

Also the interactive Mindi simulator tool enables designers to quickly generate circuit diagrams, simulate circuits and specify passive components for a variety of power and battery-charger applications. Circuits developed using the Mindi tool can be downloaded to a PC or workstation, and are often ported directly into system diagrams.

Device Packaging and Availability

The MCP6V0X op amps are now available for sampling and purchase. All of the new op amps are available in 8-pin SOIC packages, with the MCP6V02 also offered in a 4 mm x 4 mm DFN package.
