描述 Description

The TLV387, TLV2387, and TLV4387 (TLVx387) family of precision amplifiers offers state-of-the-art performance. With zero-drift technology, the TLVx387 offset voltage and offset drift provide unparalleled long-term stability. With a mere 570?μA of quiescent current, the TLVx387 are able to achieve 5.7?MHz of bandwidth, a broadband noise of 8.5?nV/√Hz, and a 1/f noise at 177?nVPP. These specifications are crucial to achieve extremely-high precision and no degradation of linearity in 16?bit to 24?bit analog to digital converters (ADCs). The TLVx387 feature flat bias current over temperature; therefore, little to no calibration is needed in high input impedance applications over temperature.

All versions are specified over the industrial temperature range of –40°C to +125°C.
