Frequently Asked Questions
What is the INA133UA/2K5E4 and what does it do?
The INA133UA/2K5E4 is a precision unity-gain difference amplifier from Texas Instruments in a SOIC-8 package (tape and reel, 2500 pcs). It amplifies the difference between two input signals while rejecting common-mode noise, with a minimum 80dB CMR. It operates from 4.5V to 36V supply and covers -40C to +125C, making it suited for industrial signal conditioning and bridge sensor interfaces.
What package and pin count does the INA133UA/2K5E4 use?
The INA133UA/2K5E4 uses the SOIC-8 (Small Outline IC, 8-pin) package with 1.27mm pitch. The 2K5E4 suffix denotes tape and reel packaging with 2500 units per reel, suitable for automated SMT assembly.
What are compatible alternatives to the INA133UA/2K5E4?
Compatible alternatives include the INA132 (similar pinout, lower cost), INA2132 (dual channel version), and AD8276 from Analog Devices (unity-gain difference amplifier). For higher precision, the INA188 or INA821 instrumentation amplifiers offer adjustable gain with even better CMR.
What is the price and availability of INA133UA/2K5E4?
The INA133UA/2K5E4 is available from $4.45 per unit at qty 1, with price breaks down to $1.70 at qty 176+. MOQ is 1 piece. FindMyChip ships globally and can source small to large quantities on inquiry.
Is the INA133UA/2K5E4 RoHS compliant?
Yes, the INA133UA/2K5E4 is RoHS compliant and lead-free. The E4 suffix confirms it meets TI green/RoHS requirements with a Pb-free finish and halogen-free packaging.
