The DG333A, DG333AL 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, DG333AL minimize measurement errors by offering low on-resistance (25 Ω typ), low leakage (20 pA typ.) and low charge injection performance. The DG333AL features micro-power operation (< 1 μW 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, DG333AL 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.
