ELECTRICAL CHARACTERISTICS—Single +12V Supply (continued)

(V+ = +12V, V- = 0, VA_H = +2.4V, VA_L = +0.8V, VEN = +2.4V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at

TA = +25°C.) (Note 2)

SWITCH DYNAMIC CHARACTERISTICS

POWER SUPPLY

Note 2:

The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.

Note 3:

NO_ pins are fault protected and COM_ pins are not fault protected. The max input voltage on NO_ pins depends on the

COM_ load configuration. Generally the max input voltage is ±36V with ±15V supplies and a load referred to ground. For

more detailed information refer to

NO_ Input Voltage section.

Note 4:

Guaranteed by design.

Note 5:

∆RON = RON(MAX) - RON(MIN).

Note 6:

Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed by correlation at TA = +25°C.

Note 7:

Off-isolation = 20log10 (VCOM_ / VNO_ ), where VCOM_ = output and VNO_ = input to off switch.

Note 8:

Between any two analog inputs.

Note 9:

Leakage testing for single-supply operation is guaranteed by testing with dual supplies.

Note 10: Guaranteed by testing with dual supplies.
