The LMP7731 is a single, low noise, rail-to-rail input and output, low voltage amplifier.
The LMP7731 is part of the LMP precision
amplifier family and is ideal for precision and low noise applications with low voltage
This operational amplifier offers low voltage noise of 2.9 nV/√Hz with a 1/f corner of
only 3 Hz. 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 level 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 accurate signal conditioning in
applications with high closed loop gain requirements.
The LMP7731 has a supply voltage range of 1.8V to 5.5V, making it an ideal choice for
battery operated portable applications.
The LMP7731 is offered in the space saving 5-Pin SOT-23 and 8-Pin SOIC packages.
