DG408 Maxim, DG408 Datasheet - Page 4

• Manufacturer Part Number: DG408
• Description: Maxim's redesigned DG408 and DG409 CMOS analog multiplexers now feature guaranteed matching between channels (8Ω max) and flatness over the specified signal range (9Ω max)
• Manufacturer: Maxim

Improved, 8-Channel/Dual 4-Channel,
CMOS Analog Multiplexers
ELECTRICAL CHARACTERISTICS—Single Supply
(V+ = 12V, V- = 0V, GND = 0V, V
Note 2: The algebraic convention where the most negative value is a minimum and the most positive value a maximum is used in
Note 3: Guaranteed by design.
Note 4: ΔR
Note 5: Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25°C.
Note 6: Off isolation = 20log V
