Frequently Asked Questions

What is the INA2133UAE4?

The INA2133UAE4 is a dual, rail-to-rail output difference amplifier from Texas Instruments. It integrates four precision 100kΩ resistors per channel, operates from a single 5V supply, and accepts differential inputs up to ±15V. The UAE4 suffix denotes the compact UQFN-8 (2mm x 2mm) package.

What package and pin count does INA2133UAE4 use?

INA2133UAE4 comes in an 8-pin UQFN (Ultra-thin Quad Flat No-Lead) package measuring 2mm x 2mm. Its small footprint makes it suitable for space-constrained PCB layouts in portable and wearable devices.

What are the typical applications for INA2133UAE4?

Typical applications include industrial signal conditioning, battery cell voltage monitoring, motor current sensing, bridge sensor amplification, and differential-to-single-ended signal conversion in portable instrumentation and data acquisition systems.

What is a suitable replacement or alternative for INA2133UAE4?

Compatible alternatives include the INA2132 (single-supply dual difference amplifier) and INA133 (single-channel equivalent). The AD8270 from Analog Devices offers a similar dual difference amplifier function with pin-compatible options.

Is INA2133UAE4 RoHS compliant and what is the operating temperature?

Yes, INA2133UAE4 is RoHS compliant and lead-free. It supports an extended industrial temperature range of -40°C to +125°C, making it suitable for harsh environments and automotive-adjacent applications.
