2.9 nV/sqrt(Hz) Low Noise, RRIO Amplifier
General Description
The LMP7732 is a dual low noise, rail-to-rail input and output,
low voltage amplifier. The LMP7732 is part of the LMP
plifier family and is ideal for precision and low noise applica-
tions with low voltage requirements.
This operational amplifier offers low voltage noise of 2.9 nV/
junction 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 LMP7732 an excellent choice for
photometry applications.
The LMP7732 provides a wide GBW of 22 MHz while con-
suming only 4 mA of current. This high gain bandwidth along
with the high open loop gain of 130 dB enables accurate sig-
nal conditioning in applications with high closed loop gain
requirements.
The LMP7732 has a supply voltage range of 1.8V to 5.5V,
making it an ideal choice for battery operated portable appli-
cations.
The LMP7732 is offered in the 8-Pin SOIC and MSOP pack-
ages.
The LMP7731 is the single version of this product and is of-
fered in the 5-Pin SOT-23 and 8-Pin SOIC packages.
