Frequently Asked Questions
What is the INA105KU and what does it do?
The INA105KU is a precision unity-gain differential amplifier from Texas Instruments. It uses laser-trimmed resistors to achieve a minimum 86dB CMRR, making it ideal for accurately amplifying small differential signals while rejecting large common-mode voltages in industrial instrumentation applications.
What package and pin count does the INA105KU use?
The INA105KU comes in an SOIC-8 (SO-8) surface-mount package with 8 pins. This compact package allows for easy PCB integration in space-constrained designs while maintaining excellent thermal and electrical performance.
What is the operating temperature range of the INA105KU?
The INA105KU is rated for an industrial operating temperature range of −40°C to +85°C, making it suitable for harsh outdoor and factory automation environments where wide thermal variation is expected.
What are good alternatives to the INA105KU?
Close alternatives to the INA105KU include the INA105KU/2K5 (tape-and-reel variant), the AD8276 from Analog Devices (unity-gain differential amplifier, MSOP-8), and the INA132 for lower supply voltage applications.
Is the INA105KU RoHS compliant and lead-free?
Yes, the INA105KU is RoHS compliant and uses lead-free (Pb-free) solder terminations, meeting EU RoHS Directive requirements for environmentally responsible manufacturing.
