INA126U

The Texas Instruments INA126U is a versatile, microPower instrumentation amplifier featuring a low quiescent current of 175 µA per channel. It operates over a wide supply voltage range, from ±1.35V to ±18V, and supports a maximum supply of 36V. This amplifier boasts a low input offset voltage of 250 µV maximum and a low input offset drift of 3 µV/°C maximum, ensuring stable performance.

With a voltage gain adjustable from 5 to 10000 V/V, the INA126U provides flexibility for various signal conditioning needs. Its low noise characteristic, with 35 nV/√Hz at 1 kHz, makes it suitable for sensitive measurements. The device also features a low input bias current of 25 nA maximum.

Available in multiple package options including SOIC, VSSOP, and PDIP, the INA126U is designed for surface mount or through-hole applications. Its operating temperature range spans from -40°C to +85°C, making it suitable for a broad spectrum of industrial and commercial environments. The amplifier's output swing headroom is 0.8V to the negative supply and -0.75V to the positive supply, providing ample dynamic range.

The INA126U is an excellent choice for applications requiring precise amplification of small differential signals in the presence of large common-mode voltages, such as sensor signal conditioning, data acquisition systems, and portable instrumentation.
