TPA5511

概述

The TPA551x is the nano-power, zero-drift amplifier with a maximum 30-μV low-offset voltage and stable frequency response for the high-precision sensing application that also requires low standby power.

The TPA551x devices provide rail-to-rail input and output. The devices have excellent AC performance with 9-kHz bandwidth, 3-V/ms slew rate while only drawing 650-nA quiescent current per amplifier.

The TPA5511 and TPA5511U (1-ch version) are offered in the SOT23-5 and SOT353 (SC70-5) packages. The TPA5512 (2-ch version) is available in the SOP8, TSSOP8, MSOP8, DFN1.5X1.5-8, and DFN2X2-8 packages. All versions can be operated over the industrial temperature range from −40°C to +125°C.
