TPA5581

5-V, Zero-Drift, RRIO, 15-MHz, Presicion Op Amp

Overview

The TPA558x is the newest zero-drift amplifier with maximum 20-μV low-offset voltage, low noise, and stable high-frequency response. It incorporates proprietary and patented design techniques to achieve excellent AC performance with 15-MHz bandwidth, 4.9-V/μs slew rate, and low distortion while drawing 1-mA quiescent current per amplifier. The input common-mode voltage extends to V–, and the output swings rail-to-rail. The amplifier can be used as a plug-in replacement for many commercially available op-amps to improve performance. Considering the requirement of the low standby power in some special applications, there is a shutdown function which is TPA558xN series with only 7.5-μA shutdown current. 

The TPA5581 and TPA5581U (1-ch veision) are offered in the SOT23-5 and SC70-5 packages. The TPA5582 (2-ch version) is available in the SOP-8, TSSOP-8, MSOP-8, and DFN-8 packages. The TPA5581N (shutdown version) is only offered in the SOT23-5 package. All versions can be operated over the industrial temperature range of -40°C to +125°C.
