Overview
The TPA552x is a series of low-power, zero-drift amplifiers with maximum 30-μV low-offset voltage and stable frequency response for the high-precision sensing application that also requires low standby power.
The TPA552x devices provide rail-to-rail input and output. The devices have excellent AC performance with 78-kHz bandwidth, 20-V/ms slew rate while only drawing 9.8-μA quiescent current per amplifier.
The TPA5521 and TPA5521U (1-ch version) are offered in the SOT23-5, DFN1×1.4-4, and SOT353 (SC70-5) packages. The TPA5522 (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.
