7 Detailed Description

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 and wide supply voltage range of 2.7 V to 12 V. The LMP7704-SP has a very

low input bias current of only ±200 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 excellent choices for low-voltage precision applications with extensive temperature

requirements.

The LMP7704-SP have only ±37 μV of typical input-referred offset voltage. This minimal offset voltage allows

more accurate signal detection and amplification in precision applications.

The low input bias current of only ±200 fA along with the low input-referred voltage noise of 9 nV/√Hz gives 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.
