3 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.
