The TLVx825 family of single, dual, and quad channel operational amplifiers enable precision performance such as lower offset, lower offset drift over temperature, greater offset stability over time and a flat noise floor. This level of performance is crucial to a variety of systems focusing on precision voltage sensing from sensors and precision current sensing using smaller shunt resistors.

TLVx825 uses zero-drift architecture to achieve an input referred offset voltage of 4µV, an offset drift of 0.02µV/°C and a low frequency noise of 320nVPP in the standard 0.1 – 10Hz range. This combination of specs provides excellent accuracy in high gain applications, thereby greatly reducing the need for system level calibration.

Additionally, with a quiescent current of 500µA, the TLVx825 is able to achieve a bandwidth of 3.5MHz and a broadband noise of 15nV/√Hz. This ability is crucial to achieve higher linearity, and signal-to-noise ratio in applications involving higher resolution, mid-speed analog to digital converters (ADCs) while minimizing system power.

TLVx825 is operational from 1.8V to 5.5V, and is available in standard packages for broader industrial applications as well as the micro-size packages to fit in the space-constrained portable applications. The devices are specified for operation from –40°C to +125°C.
