Product Description
Texas Instruments OPA657UB is a high-speed, precision operational amplifier featuring JFET input technology (Difet) that dramatically reduces input bias current by eliminating isolation-junction leakage. It delivers an exceptional combination of speed and accuracy suitable for demanding industrial, laboratory, and instrumentation applications.
This amplifier offers a gain bandwidth product (GBP) of 1.6 GHz and a high slew rate of 700 V/μs, enabling accurate amplification of high-frequency signals with minimal distortion. The device operates with a supply voltage ranging from 8V to 12V and supports output currents up to 70 mA, making it versatile for driving various load types.
With an input offset voltage of ±2.6 mV and input offset current of ±2.5 nA, the OPA657UB ensures precise signal processing required in electrometer amplifiers, photo detector amplifiers, medical equipment, and high-accuracy data acquisition systems.
The chip is housed in a compact 8-pin SOIC surface mount package with dimensions of approximately 4.9 mm in length, 3.91 mm in width, and 1.58 mm in height. It meets the RoHS environmental standards, confirming its compliance with hazardous substance restrictions.
The device functions reliably over a wide temperature range of -40°C to 85°C but is not designed for automotive standards compatibility. The JFET input stage notably reduces bias current and improves precision. Typical applications include precision instrumentation, laboratory amplifiers, medical device signal processing, and high-accuracy sensor interfaces.
Its fast response characteristics enable it to be used in high-frequency analog circuit designs and communications equipment.
This operational amplifier is ideal for engineers and designers requiring a high-performance solution for signal amplification in industrial, laboratory, and scientific instrumentation contexts.
