National Semiconductor has announced a family of supervisory ICs with a variety of factory-programmable features that can be configured in hundreds of possible combinations.
The LMP2012WGLQMLV is a rail-to-rail output operational amplifier that uses patented techniques to measure and continually correct the input offset error voltage, while eliminating the unwanted 1/f voltage and current noise present in traditional amplifiers.
This results in a high-performance amplifier that offers unparalleled levels of accuracy and stability over time and temperature.
The device is radiation tested to 50krad (Si) and displays excellent common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) ratings of 90dB over the full space temperature range.
Operating from a supply voltage of 2.7 to 5V, the LMP2012WGLQMLV provides superior performance in transducer amplifiers, high-gain configurations, analogue-to-digital convertor (ADC) buffer amplifiers and digital-to-analogue convertor (DAC) current-to-voltage conversion applications.
The LMP2012WGLQMLV offers low input offset voltage of 60uV over the extended temperature range of -55 to +125C, 4V/us of slew rate and a wide gain-bandwidth of 3MHz for accurate signal amplification.
Other key specifications include input-referred voltage noise of 35nV/(rt)Hz and open-loop gain greater than 100dB.
The LMP2012WGLQMLV is available now in a 10-pin ceramic SOIC package.
It is space-grade qualified to MIL-STD-38535 QML level V and can be purchased as the standard military drawing (SMD) 5962L0620601VZA.
