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 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 AC and DC levels 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 1.8 V to 5.5 V, making it an ideal choice for battery operated portable applications.

The LMP7732 is offered in an 8-pin SOIC.

The LMP7731 is the single version of this product and is offered in an 5-Pin SOT23 package.
