Description and Introduction

Brown Corporation - MicroSIZE, Single-Supply CMOS OPERATIONAL AMPLIFIERS MicroAmplifier ? Series **Introduction to the OPA337EA Operational Amplifier**  

The OPA337EA is a precision, low-power operational amplifier (op-amp) designed for high-performance applications requiring minimal power consumption and excellent accuracy. This CMOS-based op-amp features a rail-to-rail output swing, making it suitable for single-supply operation in battery-powered and portable devices.  

With a quiescent current of just 17 µA, the OPA337EA is optimized for energy-efficient systems while maintaining low input offset voltage (typically 150 µV) and low noise performance. Its wide supply voltage range (2.7V to 5.5V) enhances flexibility in various circuit designs, including sensor interfaces, medical instrumentation, and industrial control systems.  

The device offers a unity-gain stable architecture, ensuring reliable operation in buffer and signal conditioning applications. Additionally, its small package options, such as the SOT-23, make it ideal for space-constrained designs.  

Engineers favor the OPA337EA for its combination of precision, low power consumption, and compact form factor, making it a versatile choice for modern electronic systems where efficiency and accuracy are critical. Whether used in portable sensors or precision measurement circuits, this op-amp delivers consistent performance with minimal power overhead.

Alternative Part Number

  • LMV321IDBVR --: Low-voltage rail-to-rail CMOS op-amp in SOT-23-5, similar bandwidth and supply range, widely available and cost-effective drop-in for many OPA337EA designs.
  • MCP6001T-I/OT --: Single general-purpose CMOS op-amp in SOT-23-5 with rail-to-rail input/output and low quiescent current, suitable replacement when exact OPA337 specs are not critical.
  • TLV2371IDBVR --: Single low-power rail-to-rail op-amp in SOT-23-5 with comparable supply voltage and output drive, good alternative when slightly higher supply current is acceptable.
