LMV831 Single/ LMV832 Dual/ LMV834 Quad 3.3 MHz Low Power CMOS, EMI Hardened Operational Amplifiers .. October 6, 2008 LMV831 Single/ LMV832 Dual/ LMV834 Quad 3.3 MHz Low Power CMOS, EMI Hardened Operational Amplifiers General Description National’s LMV831, LMV832, and LMV834 are CMOS input, low power op amp IC's, providing a low input bias current, a wide temperature range of - 40°C to 125°C and exceptional performance making them robust general purpose parts. Additionally, the LMV831/LMV832/LMV834 are EMI hardened to minimize any interference so they are ideal for EMI sensitive applications. The unity gain stable LMV831/LMV832/LMV834 feature 3.3 MHz of bandwidth while consuming only 0.24 m A of current per channel. These parts also maintain stability for capacitive loads as large as 200 p F. The LMV831/LMV832/ LMV834 provide superior performance and economy in terms of power and space usage. This family of parts has a maximum input offset voltage of 1 m V, a rail-to-rail output stage and an input mon-mode voltage range that includes ground. Over an operating range from 2.7V to 5.5V the LMV831/LMV832/LMV834 provide a PSRR of 93 d B, and a CMRR of 91 d B. The LMV831 is offered in the space saving 5-Pin SC70 package, the LMV832 in the 8-Pin MSOP and the LMV834 is offered in the 14-Pin TSSOP package.
