Description
The Texas Instruments INA118UB/2K5 is a precision, low power instrumentation amplifier designed for high-performance applications. It features a low offset voltage of 50 µV, maximum, and a low drift of 0.5 µV/°C, maximum. The device has a high common-mode rejection ratio (CMR) of 110 dB, minimum, making it suitable for precision instrumentation, current sensing, strain gauge amplification, and differential signal conditioning.
The INA118UB/2K5 is available in an 8-pin SOIC package and operates over a wide supply range of ±2.25 to ±18 V. It has low input bias current of 5 nA, maximum, and quiescent current of 350 µA. The device is protected against inputs up to ±40 V, making it suitable for use in industrial automation, medical instrumentation, automotive, and process control applications.

Package
The package type of INA118UB/2K5 is SOIC-8 (Small Outline Integrated Circuit - 8 pins).
Pinout
The INA118UB/2K5 has an SOIC-8 package, which means it has a pin count of 8.
According to the product description, the package is simply referred to as "SO-8" or "8-Pin plastic DIP", but I will provide you with some general information about SOIC (Small Outline Integrated Circuit) packages. In an SOIC package, the pins are exposed on all four sides of the package.
Regarding the function, since this is an instrumentation amplifier, it likely has inputs for inverting and non-inverting signals, as well as outputs to amplify or condition these signals. However, without a detailed datasheet or pin-out diagram, I cannot provide more specific information about the pin functions.
Manufacturer
The manufacturer of the INA118UB/2K5 is Texas Instruments (TI). TI is a leading semiconductor company that designs, manufactures, tests, and sells analog and embedded processing semiconductors. The company was founded in 1930 and is headquartered in Dallas, Texas, USA. TI is known for its wide range of products, including amplifiers, comparators, data converters, interface circuits, logic devices, microcontrollers, and power management solutions.
Applications
The INA118UB/2K5 is commonly used in medical instrumentation, automotive, industrial automation, and process control applications. It's well-suited for precision instrumentation, current sensing, strain gauge amplification, and differential signal conditioning due to its high common-mode rejection ratio and low input bias current.
Equivalent
According to Texas Instruments, a newer version of this device is now available: INA818. This suggests that INA118UB/2K5 has been discontinued or replaced by INA818. Therefore, the equivalent product of INA118UB/2K5 is likely INA818.
