DESCRIPTION

The DG441LE, DG442LE monolithic quad

single-pole-single-throw analog switches are designed to

provide high speed, low error switching of analog signals.

The DG441LE has a normally closed function. The DG442LE

has a normally open function.

The DG441LE, DG442LE feature low charge injection of a

few picocoulombs over the full analog switch range.

Combining low on resistance (16 , typ.), low parasitic

capacitance (CD(ON) 15 pF), and fast switching speed

(tON, 18 ns, typ.), the devices are ideal for data acquisition,

sample-and-hold, and ADC input circuit designs.

The DG441LE, DG442LE operate on single and dual

supplies. Single supply voltage ranges from 3 V to 16 V while

dual supply operation is recommended with ± 3 V to ± 8 V.

Each switch conducts equally well in both direction when

on, and blocks input voltages up to the supply levels when

off.

The DG441LE, DG442LE are available in 16 lead TSSOP,

SOIC, and PDIP packages.
