Precision CMOS Operational Amplifier
[Product Name]	AK2970
[Abstract]	2CH Precision Op Amp
[Application]	Bridge Amp. , Thermometer, Strain-gauge Amp. etc.
[Background]	AK2970 is Precision CMOS Op Amp which operating voltage is 13.2V(max). AK2970 is a zero drift type Op Amp, its Offset voltage is very small, and is ±20A(max.) And a temperature drift is also very small, and is ±50nV/°C. AK2970 is CMOS Op Amp, therefore input/output range is full swing. Conventional zero drift Op Amp has a issue which operating characteristic changes at the switching timing of the chopper clock, but AK2970 improved them. Because AK2970 have dual NULL amplifier, either the NULL amplifier is always driving MAIN amplifier , it realizes a very stable offset characteristic and a noise performance ,even if the chopper clock switching period.
