Microchip debuts low-power, high-precision op amps

Chandler, Ariz.—Microchip Technology Inc. has expanded its line of high precision op amps with three new families of low-power devices that feature an offset voltage of just 150 microvolts.

The MCP6051/2/4 (MCP605X), MCP6061/2/4 (MCP606X) and MCP6071/2/4 (MCP607X) extend Microchip's high-precision op amp line with gain bandwidth product (GBWP) from 10 kHz to 50 MHz. The MCP605X op amps have a GBWP of 385 kHz and a quiescent current of 30 microamperes. The MCP606X op amps have a GBWP of 730 kHz and a quiescent current of 60 microamperes. The MCP607X op amps have a GBWP of 1.2 MHz and a quiescent current of 110 microamperes.

The MCP6051/2/4 (MCP605X), MCP6061/2/4 (MCP606X) and MCP6071/2/4 (MCP607X) are well suited for applications requiring low power consumption, low-voltage operation and high precision, such as those in the industrial, medical, consumer and other markets.

The MCP605X/6X/7X op amps are trimmed in-package to enable their low offset voltage, which results in reduced error at high gains. The devices feature operating voltage from 1.8V to 6.0V, making them well-suited for portable applications; and their rail-to-rail input and output provides greater dynamic range, even at lower operating voltages. Additionally, they are unity-gain stable and operate over the extended temperature range of -40 to 125°C.

PCB footprints and schematic symbols are expected to be available in August 2009 from Microchip's Web site at www.microchip.com/cad. The downloads will be available in a neutral format that can be exported to the leading EDA CAD/CAE design tools using the Ultra Librarian Reader from Accelerated Designs Inc.

Pricing: In 10K unit quantities ranges from $0.46 to $1.21, depending on package.
Availability: Samples and volume production quantities can be ordered in late June 2009.

Datasheets: MCP6051/2/4, MCP6061/2/4 and MCP6071/2/4.
