The LMV831, LMV832, and LMV834 are operational amplifiers with excellent specifications, such as low offset, low noise and a rail-to-rail output. The EMI hardening makes the LMV831, LMV832 or LMV834 a must for almost all operational amplifier applications that are exposed to Radio Frequency (RF) signals such as the signals transmitted by mobile phones or wireless computer peripherals. The LMV831, LMV832, and LMV834 will effectively reduce disturbances caused by RF signals to a level that will be hardly noticeable. This again reduces the need for additional filtering and shielding. Using this EMI resistant series of operational amplifiers will thus reduce the number of components and space needed for applications that are affected by EMI, and will help applications, not yet identified as possible EMI sensitive, to be more robust for EMI.
