The AD8170 appears at the end of a signal attenuation chain. In signal processing normally one would want to use a LNA before going to an attenuator after an antenna but we are not doing that to due the complexity. The AD8170 is driving another vendor…
I downloaded spice model of AD8170 from AD official page, but faced with this error when I simulated a simple test circuit in LTSpice.
anyone knows what it means?
I am seraching for a an analog multiplexer with a very low "total" input capacitance value.
Output capacitance information exist only for AD8174 /"Output Capacitance Disabled (AD8174) 7.5 pF" page 3 of datasheet) when disable so could I…
Hi Hoang Dao,
The AD8182 does not have a spice model yet. But for simulation purposes, you can use the spice model of AD8170 attached. It has almost same specs and performance with AD8182, the difference is that it is a single 2:1 Mux, 250 MHz Bandwidth…
I'm searching for a analog 6:1 video switch and if possible with audio. Otherwise I need another IC for doing the audioswitching.
I found the AD8174 (http://www.analog.com/static/imported-files/data_sheets/AD8170_8174.pdf) but this…

About your answers
1. Ok so I have to test several large caps till reaching proper ripple in low frequencies, is it right?
2. I have to use an analog front end circuit for conditioning sinwave inputs. Pls consider these notes about…
I have few suggestions that you may consider for your design.
1. Your 50ohms resistor is too low to be a load of your in amp. This will dissipate a lot of power. It would be better if you increase the resistance and reduce the 1uF capacitor…
