TPA5511

3.3-V, 9-kHz, Zero-Drift, Nanopower OP Amps

Overview

The TPA551x is the nano-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 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 veision) 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.
