DESCRIPTION

Description

OVERVIEW

Product Overview

OPA4991IRUCR is an operational amplifier from Texas Instruments, belonging to analog signal conditioning ICs. It is used to amplify, buffer, filter, or level-shift analog signals in sensor signal acquisition, instrumentation, and control loops. As a general-purpose op amp, it can be used to build basic circuits such as inverting, non-inverting, differential, and integrator configurations. Its package suits space-constrained board layouts. Specific bandwidth, offset voltage, noise, supply range, and output drive capability should be confirmed from the original datasheet; no values should be assumed without provided documentation.

APPLICATIONS

Applications

  • Amplification and buffering in sensor signal acquisition.
  • Signal conditioning and filtering in instrumentation circuits.
  • Error amplification or signal comparison in control loops.
  • Analog signal level shifting in portable devices.
FEATURES AND BENEFITS

Features and Benefits

  • General-purpose op amp architecture configurable for various basic amplifier circuits.
  • Suitable for analog signal conditioning and buffering applications.
  • Compact package for high-density board layouts.
  • Usable in sensor interfaces and instrumentation signal chains.
ADDITIONAL DETAILS

Additional Details

When purchasing, verify package, operating temperature range, and supply conditions against the design; specific bandwidth, offset, and noise parameters are subject to the original datasheet. Confirm ordering suffix and packaging.

Verify product details against the manufacturer datasheet before purchase.
