LMP7731 2.9 nV/sqrt(Hz) Low Noise, Precision, RRIO Amplifier
General Description
The LMP7731 is a single, low noise, low offset voltage, railto-rail input and output, low voltage precision amplifier.

The LMP7731 is part of the LMP® precision amplifier family and is ideal for precision and low noise applications with low voltage requirements. This operational amplifier offers low voltage noise of 2.9 nV/ with a 1/f corner of only 3 Hz and low DC offset with a maximum value of ±40 µV, targeting high accuracy, low frequency applications. The LMP7731 has bipolar input stages with a bias current of only 1.5 nA. This low input bias current, complemented by the very low AC and DC levels of voltage noise, makes the LMP7731 an excellent choice for photometry applications. The LMP7731 provides a wide GBW of 22 MHz while consuming only 2 mA of current. This high gain bandwidth along with the high open loop gain of 130 dB enables accura
