Overview
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 SC70-5 packages. The TPA5512 (2-ch version) is available in the SOP-8, TSSOP-8, MSOP-8, and DFN-8 packages. All versions can be operated over the industrial temperature range of −40°C to +125°C.
