DG421AK

改进的低功耗， CMOS模拟开关与门锁 Improved Low-Power, CMOS Analog Switches with Latches

General Description

Maxim’s redesigned DG421/DG423/DG425 monolithic analog switches now feature guaranteed on-resistance matching 3Ωmax between switches and on-resistance flatness over the signal range 4Ωmax. These low on resistance switches 20Ωtyp conduct equally well in both directions. They guarantee a low charge injection of 15pC maximum and an ESD tolerance of 2000V minimum per Method 3015.7. Off leakage current over temperature has also been reduced less than 5nA at +85°C.
