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-W typ), low leakage (20-pA typ) and low charge injection performance. The DG333AL features micro-power operation (<1-mW typ). This is ideal for battery operated systems. Pin 15 is not connected on the DG333A.
