DG333A, DG333AL Vishay Siliconix Precision Quad SPDT Analog Switch DESCRIPTION FEATURES 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 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. ± 22 V supply voltage range TTL and CMOS compatible logic Low on-resistance (25 ) On-resistance matched between channels (< 2 ) Flat on-resistance over analog signal range ( < 3 ) Low charge injection (1 pC) Low leakage (0.2 nA) Fast switching (175 ns) Single-supply operation (5 V to 40 V) ESD tolerance > 2 kV per 3015.x Low power (< 1 µA) - DG333A, DG333AL BENEFITS • • • • • • • • Rail-to-rail analog signal range Simple logic interface High precision and accuracy Minimal transients Low distortion Reduced power consumption Improved reliability Break-before-make switching action APPLICATIONS • • • • • • • • • Audio switching Test equipment Portable instrumentation Communication systems PBX, PABX Computer peripherals Mass storage systems Switched-capacitor networks Battery-powered systems FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION Dual-In-Line and Wide-Body SOIC IN1 1 20 IN4 S1 2 19 S8 D1 3 18 D4 S2 4 17 S7 V- 5 16 V+ GND 6 15 VL (DG333AL Only) S3 7 14 S6 D2 8 13 D3 S4 9 12 S5 IN2 10 11 IN3 Top View Document Number: 70803 S11-0154-Rev.
