Transcription

1 Low-Voltage, Low R ON, SPDT Audio Switch with Negative Swing Capability DG6, DG63 DESCRIPTION The DG6, DG63 is a low on-resistance, single-pole/ double-throw monolithic CMOS analog switch with negative signal swing capability. It is designed for low voltage applications. The DG6, DG63 is ideal for portable and battery powered equipment, requiring high performance and efficient use of board space. In additional to the low on-resistance (. Ω at.7 V), the DG63 has a typical off isolation and crosstalk of - 67 db and - 73 db respectively. The DG6, DG63 is built on s low voltage process. Break-before-make is guaranteed. As a committed partner to the community and the environment, manufactures this product with the lead (Pb)-free device terminations. For analog switching products manufactured with % matte tin device terminations, the lead (Pb)-free -E3 suffix is being used as a designator. FEATURES Low voltage operation (.8 V to 5.5 V) Low on-resistance - R ON :. Ω at.7 V High bandwidth BENEFITS Negative signal swing capability Shunt switch to eliminate switching noise Simplified design with direct DC coupling Space saving SC-89 package APPLICATIONS Cellular phones Portable multimedia players PDAs and hand-held devices Laptop computers FUNCTIONAL BLOCK DIAGRAM AND P CONFIGURATION DG6 6 NO (Source ) NC (Source ) Ax TRUTH TABLE Logic NC NO ON OFF OFF ON Top View Device Marking: Dx Pin MERCIAL ORDERG FORMATION DG63 x = Date/Lot Traceability Code Temp Range Package Part Number 6 5 NO (Source ) - 4 C to 85 C SC-89 (SOT-666) Lead (Pb)-free with Tape and Reel DG6DX-T-E3 DG63DX-T-E3 3 4 NC (Source ) Top View Device Marking: Ex ABSOLUTE MAXIMUM RATGS T A = 5 C, unless otherwise noted Parameter Symbol Limit Unit -.3 to + 6 Reference a -.3 to ( +.3) V, NC, NO a ( - 6) to ( +.3) Continuous Current (NO, NC, pins) ± 5 Peak Current (Pulsed at ms, % duty cycle) ± 3 ma Storage Temperature D Suffix - 65 to 5 C Power Dissipation (Packages) b SC-89 c 7 mw Notes: a.
