改进的双路，高速模拟开关 Improved, Dual, High-Speed Analog Switches
General Description
Maxim"s redesigned DG401/DG403/DG405 analog switches now feature guaranteed low on-resistance matching between switches 2Ωmax and guaranteed on-resistance flatness over the signal range 3Ωmax. These low on-resistance switches 20Ωtyp conduct equally well in either direction and are guaranteed to have low charge injection 15pC max. The new design offers lower off leakage current over temperature less than 5nA at +85°C.
