illustrate
LMP7707/LMP7708/LMP7709 devices are single, double and quadruple low-offset voltage, rail-to-rail input and output precision amplifiers, each with a CMOS input stage and a wide supply voltage range. The LMP7707/LMP7708/LMP7709 is part of LMP's family of high-precision amplifiers, ideal for sensor interfaces and other instrumentation applications. These decompensated amplifiers are stable at 6 and higher gains.
Guaranteed low input bias current less than ± 1 pA LMP7707/LMP7708/LMP7709 ideal for precision applications ± low offset voltage of 200μV. LMP7707/LMP7708/LMP7709 utilizes VIP50 technology, which enables a combination of CMOS input stages and a rail-to-rail common-mode voltage capability range of 12V supply voltages. LMP7707/LMP7708/LMP7709 are ideal for many applications where traditional CMOS devices cannot operate due to voltage conditions.
The unique design of each LMP7707/LMP7708/LMP7709 rail-to-rail input stage greatly reduces the CMRR glitch typically associated with rail-to-rail input amplifiers. In the free input phase, both sides have been trimmed to reduce the difference between NMOS and PMOS offset. The 40 millivolt output swing of the railway is required to maximize the signal dynamic range in low supply voltage applications.
LMP7707 is to provide space-saving 5-pin SOT23 and 8-pin SOIC packages, LMP7708 8-pin MSOP and 8-pin SOIC packages, LMP7709 are four- and 14-pin SOIC packages available in 14-pin TSSOP packages. These are ideal solutions for PC boards and portable electronics with limited footprint in a small package.
