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 mA of current per channel. These parts also maintain stability for capacitive loads as large as 200 pF. 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 mV, a rail-to-rail output stage and an input common-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 dB, and a CMRR of 91 dB. 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.
The LMV831 (single), LMV832 (dual) and LMV834 (quad) are low‑power CMOS operational amplifiers with EMI‑hardening, rail‑to‑rail output, and a wide supply range of 2.7 V to 5.5 V. They are suited for battery‑powered and portable equipment, offering a 3.3 MHz gain‑bandwidth product and low input bias current.
