DESCRIPTION
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.
