Description and Introduction

SoundPlus? Audio Operational Amplifier with Low Distortion, Low Noise and Precision 8-SOIC -40 to 85 # Introduction to the OPA2134UAG4 Operational Amplifier  

The OPA2134UAG4 is a high-performance operational amplifier (op-amp) designed for precision audio and instrumentation applications. Manufactured by Texas Instruments, this dual-channel op-amp features ultra-low distortion, low noise, and high slew rate, making it ideal for high-fidelity audio systems, active filters, and signal conditioning circuits.  

Key specifications include a wide bandwidth of 8 MHz, a low input noise density of 8 nV/√Hz, and a fast slew rate of 20 V/µs. The device operates over a wide supply voltage range (±2.25 V to ±18 V), providing flexibility in various circuit designs. Its JFET-input architecture ensures high input impedance and minimal bias current, reducing loading effects in sensitive applications.  

The OPA2134UAG4 is housed in an SOIC-8 package, offering a compact footprint for space-constrained designs. Its excellent common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) enhance performance in noisy environments.  

Engineers and designers favor this op-amp for its reliability, low power consumption, and ability to maintain signal integrity. Whether used in professional audio equipment, medical instrumentation, or industrial control systems, the OPA2134UAG4 delivers consistent, high-quality performance.

Description and Introduction

SoundPlus? Audio Operational Amplifier with Low Distortion, Low Noise and Precision 8-SOIC -40 to 85 The OPA2134UAG4 is a high-performance, dual operational amplifier (op-amp) designed for precision audio and signal processing applications. Manufactured using advanced bipolar junction transistor (BJT) technology, this component delivers exceptional sound quality, low noise, and high-speed performance, making it ideal for professional audio equipment, medical instrumentation, and industrial control systems.  

Featuring ultra-low distortion (0.00008%) and a wide bandwidth of 8 MHz, the OPA2134UAG4 ensures accurate signal amplification with minimal interference. Its low input bias current (5 pA) and high slew rate (20 V/µs) further enhance its suitability for high-fidelity audio circuits and sensitive measurement devices. The op-amp operates over a broad supply voltage range (±2.25 V to ±18 V), providing flexibility in various circuit designs.  

The OPA2134UAG4 is housed in an SOIC-8 package, offering compactness and ease of integration into PCB layouts. Its robust design includes built-in electrostatic discharge (ESD) protection, ensuring reliability in demanding environments. Whether used in preamplifiers, active filters, or data acquisition systems, this op-amp combines precision and durability, making it a preferred choice for engineers seeking high-quality signal conditioning solutions.

Alternative Part Number

  • OPA2134UA --: Same OPA2134 dual audio op-amp in SOIC-8 package; the G4 suffix only denotes lead-free/RoHS green packaging, so the base part is functionally identical.
  • OPA2134PA --: Same OPA2134 audio op-amp family in a PDIP-8 through-hole package, suitable when board layout allows DIP and electrical performance is equivalent.
  • LM4562MA --: High-performance dual audio op-amp in SOIC-8 with comparable low distortion and low noise, a common cross-family substitute for OPA2134 audio applications.
