LMV774MTX/N0PB Operational Amplifier

Updated: 2026-08-12

Overview

The LMV774MTX/N0PB is a quad-channel, low-voltage operational amplifier designed for precision applications. It belongs to Texas Instruments' LMV series, optimized for battery-powered and space-constrained designs. This IC offers excellent DC precision with low input offset voltage and drift, making it suitable for instrumentation and measurement systems. The rail-to-rail output stage provides maximum dynamic range in low-voltage applications.

Structure and Working Principle

The LMV774MTX/N0PB consists of four independent op-amps in a single package, each with differential inputs and a single-ended output. The internal architecture uses complementary MOS transistors for low power operation. When a differential voltage is applied between the inverting and non-inverting inputs, the internal gain stages amplify this difference according to the configured feedback network. The output swings close to both supply rails (rail-to-rail) for maximum signal range.

Key Features

Key characteristics include a gain bandwidth product of 1 MHz typical, low input bias current (1 pA max), and operation from 2.7V to 5.5V supplies. The device exhibits excellent power supply rejection ratio (PSRR) of 90 dB and common-mode rejection ratio (CMRR) of 80 dB, ensuring stable operation in noisy environments. Its low quiescent current (45 µA per amplifier) makes it ideal for portable applications.

Application Areas

Primary applications include portable medical devices, industrial sensor interfaces, battery-powered instrumentation, and active filter circuits. In B2B contexts, this component is commonly specified in designs for weigh scales, temperature measurement systems, and portable analytical equipment. Its small package options (such as TSSOP-14) enable high-density PCB layouts in compact products.

Maintenance and Precautions

Proper ESD handling procedures must be followed during installation, as CMOS devices are sensitive to static discharge. Thermal vias should be used for heat dissipation in high ambient temperature applications. For optimal performance, maintain clean power supplies with adequate decoupling capacitors (0.1 µF ceramic close to each supply pin). Input protection may be needed when interfacing with high-impedance sensors in electrically noisy environments.

B2B Procurement Guide

When sourcing LMV774MTX/N0PB, verify the specific suffix (N0PB) as it denotes package type and temperature range. Minimum order quantities typically start at 1,000 units for competitive pricing. Lead times vary by season; during semiconductor shortages, consider approved alternates like LMV772 or allocate buffer stock. Quality certifications (such as AEC-Q100 for automotive applications) should be confirmed when required.
