The LMP7732 is a dual low noise, rail-to-rail input and output, low voltage amplifier. The LMP7732 is part of the LMP 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/√Hz with a 1/f corner of only 3 Hz. The LMP7732 has bipolar 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 consuming only 4 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 LMP7732 has a supply voltage range of 1.8V to 5.5V, making it an ideal choice for battery operated portable applications.

The LMP7732 is offered in the 8-Pin SOIC and VSSOP packages.

The LMP7731 is the single version of this product and is offered in the 5-Pin SOT-23 and 8-Pin SOIC packages.
