INA326EA/2K5 Description

Short technical summary and product information.

The Texas Instruments INA326EA/2K5 is a cost-optimized, precision instrumentation amplifier designed for a wide range of applications. It operates from a single supply voltage of +2.7V to +5.5V and features true rail-to-rail input and output capabilities. This amplifier boasts a low input offset voltage of 100 µV (max) and a low offset drift of 0.4 µV/°C (max), ensuring high accuracy and stability.

 

With a voltage gain range from 0.1 V/V to 1000 V/V, the INA326EA/2K5 is suitable for amplifying low-level signals from sources such as bridges, load cells, and thermocouples. It offers excellent long-term stability and very-low 1/f noise, making it ideal for high-resolution test systems and multi-channel data acquisition.

 

The device is available in a small VSSOP (DGK) 8-pin package, measuring 14.7 mm² (3 mm x 4.9 mm), which is suitable for space-constrained designs. Its operating temperature range is -40°C to 85°C, providing reliable performance in various environmental conditions.

 

Key electrical characteristics include a typical noise at 1 kHz of 33 nV/√Hz, a minimum CMRR of 100 dB, and a typical quiescent current of 2.4 mA. The input common-mode range extends to 20mV below the negative rail, and the output swing is within 10mV of the rails.
