描述

 

Texas Instrument’s LMV851/LMV852/LMV854 are CMOS input, low power op amp ICs, 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 LMV851/LMV852/LMV854 are EMI hardened to minimize any interference so they are ideal for EMI sensitive applications. The unity gain stable LMV851/LMV852/LMV854 feature 8 MHz of bandwidth while consuming only 0.4 mA of current per channel. These parts also maintain stability for capacitive loads as large as 200 pF. The LMV851/LMV852/LMV854 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 supply range from 2.7V to 5.5V the LMV851/LMV852/LMV854 provide a CMRR of 92 dB, and a PSRR of 93 dB. The LMV851/LMV852/LMV854 are offered in the space saving 5-Pin SC70 package, the 8-Pin VSSOP and the 14-Pin TSSOP package.
