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.
