7.1 Overview

The LMP7704-SP is a radiation-hardened, quad, low offset voltage, rail-to-rail input and output precision amplifier with a CMOS input stage. The LMP7704-SP has a wide supply voltage range of 2.7 V to 12 V and a very low input bias current of only ±500 fA at room temperature.

The wide supply voltage range of 2.7 V to 12 V over the extensive temperature range of −55°C to +125°C makes the LMP7704-SP an excellent choice for low-voltage, precision applications with extensive temperature requirements.

The LMP7704-SP has only ±60 μV of input-referred offset voltage. This offset voltage allows for more accurate signal detection and amplification in precision applications.

The low input bias current of only ±500 fA along with the low input-referred voltage noise of 9 nV/√Hz give the LMP7704-SP superiority for use in sensor applications. Lower levels of noise from the LMP7704-SP mean better signal fidelity and a higher signal-to-noise ratio.
