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.
