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.
