illustrate
National Semiconductor's LMV831, LMV832 and LMV834 are CMOS input, low-power operational amplifier ICs that offer low input bias current, a wide temperature range of -40°C to 125°C and excellent performance, making them powerful general-purpose components. In addition, the LMV831/LMV832/LMV834 EMI hardening to minimize any interference, making them ideal for EMI-sensitive applications.
Unity-gain stabilized LMV831/LMV832/LMV834 function 3.3 MHz It also consumes only 0.24 mA of current with the bandwidth of each channel. These components are also stable for large capacitive loads of 200 pF. The LMV831/LMV832/LMV834 offer superior power and space usage and economy.
The maximum input offset voltage for this part of the home 1 mV A rail-to-rail output stage and input common-mode voltage range, including ground. The LMV831/LMV832/LMV834 operating from 2.7V to 5.5V offer a PSRR of 93 dB and CMRR of 91 dB. The LMV831 is available in a 5-pin SC70 package, and the 8-pin MSOP LMV832 and LMV834 are available in a 14-pin TSSOP package.
