Description and Introduction

High Precision, Low Noise Operational Amplifiers # Introduction to the OPA4228PA Operational Amplifier  

The OPA4228PA is a high-performance, quad-channel operational amplifier (op-amp) designed for precision analog applications. Manufactured by Texas Instruments, this component offers low noise, low distortion, and excellent DC accuracy, making it suitable for a wide range of signal conditioning and amplification tasks.  

Featuring a wide supply voltage range of ±4.5V to ±18V, the OPA4228PA provides flexibility in both single-supply and dual-supply configurations. Its low input bias current and high open-loop gain ensure stable performance in sensitive circuits, such as medical instrumentation, audio processing, and industrial control systems.  

Key specifications include a low offset voltage (typically 250µV), low noise density (8nV/√Hz at 1kHz), and a high slew rate (20V/µs), enabling accurate signal amplification with minimal distortion. The device also incorporates thermal shutdown and short-circuit protection, enhancing reliability in demanding environments.  

Packaged in a 14-pin PDIP (Plastic Dual In-Line Package), the OPA4228PA is compatible with standard through-hole PCB assembly techniques. Its robust design and precision characteristics make it a preferred choice for engineers requiring high-performance analog signal processing in their designs.

Application Scenarios & Design Considerations

High Precision, Low Noise Operational Amplifiers

Alternative Part Number

  • OPA4277PA --: Quad precision op-amp in the same DIP-14 package with similar low offset and low noise, direct functional replacement for OPA4228PA.
  • LT1014CN --: Quad precision op-amp in DIP-14 with comparable offset voltage and drift, suitable substitute when OPA4228PA is unavailable.
  • MC33074APG --: Quad general-purpose op-amp in DIP-14 with similar supply range and pinout, usable as a lower-cost alternative for less demanding applications.
