Low power amplifiers

Features: Microchip Technology Inc, provider of microcontroller and analog semiconductors, has announced the launch of low power, high-precision operational amplifiers.

The MCP6031, MCP6032, MCP6033 and MCP6034 (MCP603X) operational amplifiers (op amps) 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 said in a statement.

"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."

Microchip's low-power CMOS technology and implementation of non-volatile memory for in-package trimming enables the MCP603X amplifiers' extremely low offset. This minimises 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.
