概述
The TPA558x is the newest zero-drift amplifier with a 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 commercially available op-amps to improve performance. Considering the requirements of the low standby power in some special applications, there is a shutdown function which is the TPA558xN series with only 7.5-μA shutdown current.
The TPA5581 and TPA5581U (1-ch version) are offered in the SOT23-5 and SOT353-5 (SC70-5) packages. The TPA5582 (2-ch version) is available in the SOP8, TSSOP8, MSOP8, DFN2X2-8, and DFN3X3-8 packages. The TPA5581N (shutdown version) is only offered in the SOT23-5 package. All versions are operated over the industrial temperature range from −40°C to +125°C.
