DG408L/409L

Notes:

a. Leakage parameters are guaranteed by worst case test condition and not subject to production test.

b. Room = 25 °C, Full = as determined by the operating temperature suffix.

c. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.

d. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

e. Guaranteed by design, not subject to production test.

f. VIN = input voltage to perform proper function.

Δr

DS(on) = rDS(on) Max - rDS(on) Min.

h. Worst case isolation occurs on Channel 4 do to proximity to the drain pin.

i. rDS(on) flatness is measured as the difference between the minimum and maximum measured values across a defined Analog signal.
