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 n V/√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 n A. This low input bias current, plemented 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 m A of current. This high gain bandwidth along with the high open loop gain of 130 d B 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.
