The LMP7731 is a single, low noise, rail-to-rail input and output, low voltage amplifier.
The LMP7731 is part of the LMP family of precision amplifiers and is ideal for low voltage precision and low noise applications.
This op amp provides low voltage noise of 2.9 NV /
√
Hertz with a 1/f angle of only 3 Hz.
The LMP7731 has a bipolar input stage bias current of only 1.5 nA.
This low input bias current, combined with a very low level of voltage noise, makes the LMP7731 a good choice for metering applications.
The LMP7731 delivers a 22 MHz wide GBW while consuming only 2 mA.
This 130 dB high open-loop gain and high gain bandwidth can be used for high closed-loop gain where accurate signal conditioning is required.
The LMP7731 has a supply voltage range of 1.8V to 5.5V, making it ideal for battery-powered portable applications.
The LMP7731 is available in space-saving 5-pin SOT-23- and 8-pin SOIC packages.
