1 pC Charge Injection, 100 pA Leakage, +5 V / +3 V,

Dual SPST Analog Switches

DESCRIPTION

The DG9232E, DG9233E, and DG9234E are monolithic

CMOS switches designed for precision signal switching.

The 17

 low voltage parts feature low charge injection,

leakage, parasitic capacitance, and fast switching.

The DG9232E, DG9233E, and DG9234E can switch both

analog and digital signals. Each switch conducts equally

well in both directions when on, and blocks up to the power

supply level when off.

The DG9232E, DG9233E, and DG9234E contain two

independent single pole single throw (SPST) switches.

Switch-1 and switch-2 are normally closed for the DG9232E

and normally open for the DG9233E. For the DG9234E,

switch-1 is normally open and switch-2 is normally closed

with a break-before-make switching timing.

The DG9232E, DG9233E, and DG9234E offer 1 nW typical

power consumption and 8 kV ESD/HBM, 1 kV ESD/CDM

tolerance. They are the ideal switches for use in low voltage

instruments and healthcare devices, fitting the circuits of

low voltage ADC and DAC, sample and hold, analog front

end gain control, and signal path control. The DG9232E,

DG9233E, and DG9234E are available in 8-lead MSOP and

SOIC packages.
