Other Parts Discussed in Thread: UAF42 Hello,
I am planning to use UAF42 is a universal active filter, but the temperature range for the same is from -25 to 85.
Have checked for alternate IC's in similar category but they too have temperature range…
First, I would suggest replacing the UAF42 with an unused part to ensure that it is not damaged. Again, the V- must be connected to a negative supply voltage or ground to ensure proper operation of the part. If the circuit behaves the same after replacing…
Hello Helmet,
Is the 2 kHz noise still present when the V60PAout input is disconnected from the 200 dB gain amplifier, and then grounded? The UAF42 is intended to be driven by a source impedance which is ideally zero Ohms. I am wondering if that if…
Other Parts Discussed in Thread: UAF42 Hello,
I am trying to implement the 2nd order butterworth LP filter for cutoff frequency 70Hz using UAF42 IC and I selected the components as per FILTER42.exe DOS version software and I used subcircuit PP3 as given…
Other Parts Discussed in Thread: UAF42 , CD74HCT390 I have a square wave circuit based on a 555, (2) CD4017, a CD4013 which in turn feeds the square wave to the UAF42. Is it a requirement that the V+ and V- for the UAF42 be separate from the other IC…
Other Parts Discussed in Thread: UAF42 Hi,
I am currently testing the UAF42 as a 60 Hz notch filter for a prototype design but there is something that I misunderstand: Although the filter works fine, so it does filter the 60 Hz component quite well…
Hello Lars-Olof,
I understand your concerns about injecting an offset and how it will affect the different filter outputs. I have put together a "discrete" UAF42 TINA simulation circuit to help evaluate offset adjust possibilities. It isn't the full…

Other Parts Discussed in Thread: UAF42 Hi everyone.
I am using UAF42 to implement a high-pass filter for 10 to 30 Hz frequency range. To design the filters I use the Filter42 program as suggested on many web pages to ease my design.
The butterworth…
