Instrumentation amplifiers

Integrated resistor networks maximize accuracy and space efficiency

parametric-filterView all products
With cutting-edge process and thin-film technology, our instrumentation amplifiers achieve very high levels of direct-current (DC) precision such as offset voltage, gain error, drift and common-mode rejection. Innovative designs enable our instrumentation amplifiers to deliver unprecedented levels of speed, noise, and power while state-of-the-art packaging push the boundaries on size with 3 mm x 3-mm QFN options for maximum space savings.

Input overvoltage protection (OVP)

Enable highly robust solutions by using TI’s 36-V instrumentation amplifiers with integrated input OVP up to ±60 V and maintain higher accuracy when compared to discrete protection schemes.

checkmark

Low noise, wide-bandwidth

Enable the highest resolution measurements with TI’s high efficiency, super-beta amplifiers with the industry’s widest-bandwidth, up to 28 MHz, and ultra-low noise, 1 nV/√Hz.

checkmark

Small packages, low power

Reduce board size with leadless 3x3 mm WSON packages and extend battery life with micro-power amplifiers, down to 50 µA.
