LMP7731 is a single, low-noise, rail-to-rail input and output, low-voltage amplifier. LMP7731 is part of LMP's range of high-precision amplifiers and is ideal for precision and low-noise applications where low voltage requirements are required.
This op-amp offers a low voltage noise of 2.9 NV/√ Hz with a 3/f angle of only 1 Hz. LMP7731 has a bipolar input stage with a bias current of only 1.5 nA. This low input bias current and very low voltage noise levels make it an excellent choice for LMP7731 photometry applications.
LMP7731 provides a GBW of 22 MHz wide while consuming only 2 mA. This is accompanied by a high gain bandwidth of 130 dB with a high open-loop gain, which can be applied to accurate signal conditioning for high closed-loop gain.
LMP7731 has a supply voltage range of 1.8V to 5.5V, making it ideal for battery-powered portable applications.
LMP7731 are available in space-saving 5-pin SOT-23 and 8-pin SOIC packages.
