TPA5581 Precision Op Amps
3PEAK precision zero drift, RRIO op amps offer very low offset voltage
3PEAK TPA5581-SC5R precision op amps are zero-drift amplifiers 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 a 7.5 μA shutdown current.
