TEXAS INSTRUMENTS INA826AID Precision Instrumentation Amplifier, SOIC-8

The TEXAS INSTRUMENTS INA826AID is a high-precision instrumentation amplifier offering an exceptional combination of low power consumption, wide supply voltage range, and a rail-to-rail output stage. Housed in a compact 8-pin SOIC package, this low-cost component is engineered for reliability and stability in demanding measurement applications.

Its extremely low supply current of 150µA makes it ideal for battery-powered and portable devices, while its wide operating range from a single 2.7V to 36V supply, or dual supplies up to ±18V, provides excellent design flexibility. A single external resistor allows you to set any gain from 1 to 1000 with excellent accuracy.

Key Performance Features

The INA826AID is optimised for precision, featuring a very low offset voltage of just 150µV and a minimal gain drift of only 35ppm/°C, ensuring stable performance across a wide temperature range from -40°C to 125°C. It delivers a high common-mode rejection ratio (CMRR) of over 100dB at a gain of 10, effectively rejecting noise for clean signal acquisition. Additional built-in protection safeguards the inputs against overvoltage conditions up to ±40V beyond the power supplies, limiting input current to safe levels.

With a gain bandwidth product of 1MHz and a slew rate of 1V/µs, this amplifier is well-suited for a variety of signal conditioning tasks. Its rail-to-rail output maximises dynamic range in low-voltage systems, making it a versatile choice for modern electronic designs.

Robust and Reliable

Designed for surface-mount assembly, this instrumentation amplifier is a robust solution for industrial environments. It is important to note that this integrated circuit is sensitive to electrostatic discharge (ESD); proper handling and installation procedures must be observed to prevent damage.
