TPA5581-S5TR

The TPA558x is the latest zero-drift amplifier featuring a low offset voltage of 20 μV maximum, low noise, and stable high-frequency response. Employing proprietary and patented design techniques, it achieves excellent AC performance at only 1 mA quiescent current per amplifier, including 15 MHz bandwidth, 4.9 V/μs slew rate, and low distortion. The input common-mode voltage range extends to V–, and the output swings rail-to-rail. The amplifier can serve as a drop-in replacement for commercially available op-amps to enhance performance. To address low standby power requirements in certain specialized applications, a shutdown function is available in the TPA558xN series, with a shutdown current of only 7.5 μA. The TPA5581 and TPA5581U (single-channel versions) are offered in SOT23-5 and SOT353-5 (SC70-5) packages. The TPA5582 (dual-channel version) is available in SOP8, TSSOP8, MSOP8, DFN2X2-8, and DFN3X3-8 packages. The TPA5581N (shutdown version) is available in SOT23-5 package only. All versions operate over a temperature range of −40°C to +125°C.
