Frequently Asked Questions
What is the OPA134UA/2K5 and what does it do?
The OPA134UA/2K5 is a SoundPlus high-performance audio operational amplifier from Texas Instruments. It features an 8MHz gain-bandwidth product, ultra-low THD+N of 0.00008%, and input voltage noise of 8nV/√Hz. The '/2K5' suffix denotes tape-and-reel packaging with 2500 units per reel, suited for automated SMT assembly. It operates on supplies from ±2.5V to ±18V and is ideal for professional audio and precision signal-conditioning applications.
What package and pin count does the OPA134UA/2K5 use?
The OPA134UA/2K5 comes in an 8-pin SOIC (Small Outline Integrated Circuit) surface-mount package. The standard SOIC-8 footprint is compatible with most PCB design tools. The '/2K5' suffix indicates tape-and-reel packaging of 2500 units, optimizing it for high-volume automated pick-and-place assembly.
What is the operating temperature range of the OPA134UA/2K5?
The OPA134UA/2K5 is rated for industrial/commercial operation from −40°C to +85°C. This wide range makes it suitable for equipment used in both indoor studio environments and more demanding industrial or automotive-adjacent applications where ambient temperatures may vary significantly.
What are good drop-in alternatives to the OPA134UA/2K5?
Pin-compatible alternatives include the OPA2134UA (dual version in SOIC-8, same SoundPlus family), NE5534ADR (single-supply audio op-amp from Texas Instruments), and LM4562MA from Texas Instruments (ultra-low-noise audio op-amp). For cost-sensitive designs, the TL072CDR offers similar pinout with lower performance. Always verify supply voltage, noise, and bandwidth requirements against your specific application before substituting.
Is the OPA134UA/2K5 RoHS compliant?
Yes, the OPA134UA/2K5 is RoHS-compliant and lead-free. Texas Instruments ships this part in a halogen-free, Pb-free SOIC-8 package. It meets EU RoHS Directive 2011/65/EU and is suitable for use in consumer, professional audio, and industrial products requiring environmental compliance.
