Description and Introduction

Low Cost FET-Input Operational Amplifiers The **OPA2137EA/2K5** is a high-performance, dual operational amplifier (op-amp) designed for precision audio and signal processing applications. Known for its low noise, low distortion, and wide bandwidth, this component is well-suited for professional audio equipment, medical instrumentation, and high-fidelity systems.  

Featuring **JFET-input** technology, the OPA2137EA/2K5 offers ultra-low input bias current and high input impedance, making it ideal for applications requiring minimal signal degradation. With a **slew rate of 20 V/µs** and a **bandwidth of 8 MHz**, it ensures fast and accurate signal amplification. Additionally, its **low noise density (8 nV/√Hz)** preserves signal integrity in sensitive circuits.  

The op-amp operates over a **wide supply voltage range (±2.25 V to ±18 V)**, providing flexibility in various design configurations. Its **unity-gain stability** and **low harmonic distortion** further enhance performance in demanding environments. Packaged in a **SOIC-8** format, the OPA2137EA/2K5 is optimized for space-constrained designs while maintaining excellent thermal characteristics.  

Engineers and designers favor this component for its reliability and superior audio performance, making it a preferred choice in high-end audio amplifiers, active filters, and data acquisition systems. Its robust design ensures consistent operation across industrial and commercial applications.

Application Scenarios & Design Considerations

Low Cost FET-Input Operational Amplifiers

Alternative Part Number

  • TL072CDR --: Widely available low-noise JFET-input dual op-amp in SOIC-8, a common drop-in substitute for general-purpose audio and signal conditioning where the OPA2137 is used.
  • MC33078DR2G --: Dual low-noise bipolar op-amp in SOIC-8 with similar supply range and bandwidth, suitable replacement for the OPA2137 in audio and instrumentation circuits.
  • LM833MX/NOPB --: Dual low-noise audio op-amp in SOIC-8 offering comparable performance and pin compatibility, a practical alternative when the OPA2137 is unavailable.
