DG421中文资料美信数据手册PDF规格书

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).
