Hi
I am using the ADG719 switch. I have two inputs with a frequency of 125kHz. I am switching between the two using a logic signal of 250kHz. But when I look at the output of the switch I just see a pulse of one of the signals then about a gap of 12ms…
When I choose a proper Swith for 10MHz RF signal link swith ,is it right if i ues ADG719 in my application.
the info of ADG719 :
FEATURES1.8 V to 5.5 V single supply4 Ω (max) on resistance0.75 Ω (typ) on resistance flatness−3 dB bandwidth…
Dear Sir/Madam,
We will use the some devices. below,
ADG719BRTZ (6ld SOT-23)
ADG704BRMZ (10ld MSOP)
Could you give me the PDF-data of footprints? .
It would be greatly appreciated if advice could be gotten.
Best Regards,
Kou
Hi there
Datasheet of ADG719 (p. 4) does not give any indication regarding Idd at high temperatures (e.g. 85 deg C) or maximum rating over operating temperature range. Only value at room temperature is given. Could this be specified?
Many thanks.
Hi,
When I measured the switch-off leakage current of the ADG709, I found that the value was incorrect. The test connection diagram is shown in the figure. Why is the leakage current of the test much larger than the standard maximum value of 20nA in the…
Hi Victor,
Unfortunately, there is no available SPICE model for the ADG774. However, you may try to use four ADG719 in your simulation as a replacement of one ADG774. See link below.

I have a design that uses a ADA4896-2 in unity gain mode. I have a 5V and -2V supply. The amplifier drives a analog switch, ADG719. The amp works fine if I have the input voltage below about 4.3V. If I then increase it the output just saturates at…
目前项目设计需要用到高速开关,例如ADG901、ADG719的开关时间都在10nS以下,在实际实用中能否有什么方法使开关时间固定在某个值不变或变化在0.3nS以下?还是说开关时间最小也会有几nS的变化?
I am using an ADG719 analog switch (see circuit). I have a fixed voltage of 4.5V on an input and 0V on the other. I am switching between the inputs at 125kHz. If I look at the switch output I see some form of transient behavior (see image). It takes about…
