Precision Op Amps for Instrumentation - Microchip
Posted in Instrumentation, Measurement, MicrochipOn Tuesday, April 17, 2007
Microchip announced the MCP6031, MCP6032, MCP6033 and MCP6034 (MCP603X) precision operational amplifiers (Op Amps). This new Op Amps have very small quiescent current (900 nA), with a maximum voltage offset 150 µV. This precision Op Amps are ideal for portable, handheld electronic devices used in the industrial, consumer electronics and medical markets.
