Texas Instruments LMP7701/LMP7702 Precision Rail-to-Rail Amplifiers

National Semiconductor LMP7701/LMP7702 Precision Rail-to-Rail Amplifiers are part of the LMP® product family. These amplifiers feature single and dual low offset voltage, rail-to-rail input, output precision, CMOS input stage, and wide supply voltage range. The VIP50 technology built into the National's LMP7701/LMP7702 precision amplifiers allows the combination of a CMOS input stage and 12V common mode and supply voltage range. These amplifiers are ideal for applications where conventional CMOS parts could not operate under this and other desired voltage conditions. The rail-to-rail input stage integrated into the LMP7701/LMP7702 significantly reduces the CMRR glitch usually associated with rail-to-rail amplifiers.
