DG441LE, DG442LE
Vishay Siliconix
16 , Low Charge Injection and Leakage,
+12 V / +5 V / +3 V / ± 5 V Quad SPST Switches
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.
FEATURES
• 3 V to 16 V single supply or ± 3 V to ± 8 V dual
supply
• On-resistance RDS(on): 16
• Fast switching tON: 18 ns,typ.
• Low parasitic capacitance:
CD(ON): 15 pF
CS(OFF): 5 pF
• Less than 8 pC charge injection over the full
signal swing range
