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/√ Hz 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, complemented by a very low level of voltage noise, makes the LMP7731 an excellent choice for metering applications.
The LMP7731 provides a GBW 22 MHz wide while consuming only 2 mA. This is accompanied by a high gain bandwidth of 130 dB in the open loop and 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.
