Overview

The TPA552x is the low-power, zero-drift amplifier with maximum 30-μV low-offset voltage and stable frequency response for the high-precision sensing applicaiton 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 veision) are offered in the SOT23-5, DFN-4, and SC70-5 packages. The TPA5522 (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.
