Precision Operational Amplifiers

  • Inquiry

AKM has the lineup of the ZeroDrift type precision CMOS operational amplifier. Zero Drift op amp is featured with low offset and low temperature drift very. It is suitable for the amplification of a small sensor signal. Not only the general 5.5V type as a CMOS operational amplifier but the 13.2V type (AK2970H) is starting the production.  And it is also possible to provide ES sample AK2972S 25V.  In addition, we plan to expand the ”precision op amp wideband, low-noise” applying the trimming technology.

[New Product]

AK2970H is a precision CMOS operational amplifier which is Zero Drift type, its power supply voltage can apply up to 13.2V.  It has been designed as " very low offset voltage 10μV (max.), temperature drift 20nV/°C(max.). This is a suitable product for the amplification of the previous stage of ADC, for such as small-sensor signal.
