Why choose our instrumentation amplifiers?
High DC precision
Ensure long-term stability with zero-drift, eliminate package stress parameter shifts with e-trim, and maintain high CMRR and low gain error with highly matched 0.001% thin film resistors.
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.
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.
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.
