Analog Devices Inc. ADG798多路复用器开关IC
Analog Devices ADG798多路复用器开关IC是低压、CMOS、模拟多路复用器，能够在高达210°C的高温下工作。ADG798 IC具有低功耗以及3.3V至5.5V工作电源范围。所有通道均为先开后合式。先开后合式开关动作防止ADG798切换通道时出现瞬间短路。ADG798的开关设计具有增强型亚微米工艺。增强型亚微米工艺具有低功率损耗、高开关速度和极低导通电阻特性。最大导通电阻 (RON) 为10Ω，开关之间严格匹配，并且在整个信号范围内导通曲线非常平坦。ADG798 IC作为多路复用器或多路解复用器均同样运行良好，并具有扩展到电源的输入信号范围。ADG798多路复用器开关IC的工作温度范围为-55°C至+210°C。ADG798多路复用器开关IC设计用于在极端温度下稳健工作，可在最高额定温度下连续工作1000小时。
Analog Devices ADG798's switches are designed with an enhanced submicron process. The enhanced submicron process delivers low power dissipation, high switching speed, and low on-resistance. The maximum on-resistance (RON) of 10Ω is closely matched between switches and is very flat over the full signal range. The ADG798 ICs operate equally well as either a multiplexer or a demultiplexer and have an input signal range that extends to the supplies. The ADG798 Multiplexer Switch ICs have an operating temperature range of −55°C to +210°C. Designed for robustness at extreme temperatures, the ADG798 Multiplexer Switch ICs are qualified for 1000 hours of continuous operation at the maximum temperature rating.
