switches now feature guaranteed low on-resistance
matching between switches (2Ω max) and guaranteed
on-resistance flatness over the signal range (3Ω max).
These low on-resistance switches (20Ω typ) 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).
