The Texas Instruments INA128PA is a versatile instrumentation amplifier with a focus on precision and low power consumption. It features a wide supply voltage range from ±2.25V to ±18V, making it suitable for various applications.
Key electrical characteristics include a low input offset voltage of 50µV maximum and a low input bias current of 5nA maximum. The amplifier boasts a high Common-Mode Rejection Ratio (CMRR) of 120dB minimum and low noise performance with 8nV/√Hz at 1kHz. The gain is adjustable from 1 to 10000, with a bandwidth of 1.3MHz at minimum gain.
Designed for robustness, the INA128PA includes input protection up to ±40V. It is available in 8-pin PDIP and SOIC packages, suitable for surface-mount and through-hole designs. The low quiescent current of 700µA typical makes it an excellent choice for power-sensitive systems.
This instrumentation amplifier is well-suited for applications requiring accurate amplification of small differential signals in the presence of large common-mode voltages, such as data acquisition systems, sensor interfaces, and medical instrumentation.
