Frequently Asked Questions
What is the OPA137U and what are its key specifications?
The OPA137U is a FET-input, unity-gain stable precision operational amplifier from Texas Instruments in an SOIC-8 package. Key specifications include a 3MHz gain-bandwidth product, 7nV/rtHz input voltage noise, 5pA input bias current, and a wide supply voltage range of +/-2.5V to +/-18V. It draws only 1.5mA quiescent current and operates from -40C to +125C.
What applications is the OPA137U best suited for?
The OPA137U excels in applications requiring high input impedance and low noise, such as photodiode transimpedance amplifiers, precision instrumentation front-ends, medical biosignal acquisition, and high-impedance piezoelectric sensor interfaces. Its FET input stage makes it ideal wherever leakage current must be minimized.
What is the difference between OPA137U and OPA134UA?
The OPA137U is the single-channel, cost-optimized version of the OPA13x family, sharing the FET input architecture with the higher-spec OPA134UA. The OPA134UA offers lower noise and better THD, while the OPA137U targets cost-sensitive designs that still require FET input performance. Both are pin-compatible in SOIC-8 packaging.
What package is the OPA137U available in and how do I order it?
The OPA137U comes in an 8-pin SOIC surface-mount package with 1.27mm pitch. It is available through FindMyChip starting at $2.69 per unit for quantities of 112, dropping to $1.72 at 10,000 pieces. Minimum order quantity is 112 units, and global shipping is supported.
Is the OPA137U RoHS compliant?
Yes, the OPA137U from Texas Instruments is RoHS compliant and lead-free. It meets EU RoHS Directive restrictions on hazardous substances, making it suitable for environmentally regulated end products across consumer, industrial, and medical markets.
