Microchip Technology Launches Low-Power, High-Accuracy Op Amps

(Product News, 17 Apr 2007)

Microchip Technology Inc. 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 900nA and a bandwidth of 10kHz, with a maximum voltage offset of just 150µV at 25°C. 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.
