摘要
本文叙述了全温(-55℃～+125℃)SB508AAK八选一模拟开关的工作原理、电路设计、版图设计及研制结果。该电路在±15V电源电压工作,±22V下不产生闭锁,按B_1级考核已通过1000小时寿命试验和机械振动实验。
An 8-channel analog switch,SB508AAK, working in full temperature range(-55^+125 C ) has been developed. Its theory of operation .circuit and layout design are described and results are given in the paper. The circuit operates at +15V supply voltage and is free of latch-up at + 22V. It has passed the Class B1 qualification test through 1000-hour lifetime test and mechanical vibration experiment.
