Microchip stretches the precision capability of its operational amplifiers

Microchip has added few more new op-amps to its family of precision amplifiers with the gain bandwidth product (GBWP) ranging from 10 kHz to 50 MHz. The new MCP6051/2/4 (MCP605X), MCP6061/2/4 (MCP606X) and MCP6071/2/4 (MCP607X) op amps feature offset voltages of 150 microvolts and are suggested for low power, low-voltage applications in industrial, medical electronics and consumer electronics markets.

These operational amplifiers work from an operating voltage range of 1.8V to 6.0V and support rail-to-rail input and output features. Additionally, they are unity-gain stable and operate over the extended temperature range of - 40 to 125 degrees Celsius.

"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. "These new 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 other key specs are, 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 more exact product market suggested for these op-amps are 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.
