The DG333A/333AL consist of four independently controlled
single-pole double-throw analog switches. These monolithic
switch is designed to control analog signals with a high degree of
accuracy. The DG333A/333AL minimize measurement errors by
offering low on-resistance (25- typ), low leakage (20-pA typ)
and low charge injection performance. The DG333AL features
micro-power operation (<1-W typ). This is ideal for battery
operated systems. Pin 15 is not connected on the DG333A.
An improved charge injection compensation design minimizes
switching transients. These switches can handle up to
22-V
signals and have an improved continuous current of 30 mA.
The DG333A/333AL is fabricated in Vishay Siliconix’s proprietary
HVSG-2 CMOS process, resulting in higher speed and lower
power consumption. An epitaxial layer prevents latchup. Each
switch conducts equally well in both directions when on. When
off, they block voltages up to the power-supply levels.
