Hi There,
I have a circuit board with 9 loads (assume resistors) and each load is connecting to the input source (Sinusoidal signal) via toggle switch. so, now I've got 9 toggle switch to switch on/off
the loads. The problem is now I want to extend the number of loads to be 16 or 32 etc.. and...
Hi There,
I am working on a design requires small button batteries due to space restriction. So,
Required voltage = 3.6V - 5.5V
retainer or holder Diameter = 8 mm maximum (SMT footprint)
height = 6 mm maximum
I don't mind using stack of batteries if they satisfy the criteria above
Thanks

Hi There,
I have a Voltage comparator ADCMP600 and I am trying to set the threshold (reference) voltage to 20mV and this can be achieved by connecting 20mV to pin 4 (Inverting analog input).
My question is how to get 20mV from 3V voltage supply. I know the obvious solution is voltage divider...
Hi,
I am working on an ECG circuit.
It contains an instrumentation amplifier, two high pass filters, an amplifier and pull up resistor.
Initially, I had the pull up resistor after the amplifier and it worked.
I came today to test the circuit and it didn't work so I put the pull up resistor...
Thanks for your response,
But I am still confused about something. In the datasheet there is circuit example (Figure 1. Regenerative Feedback—High-Speed Receiver with 50Ω Input and Output Termination). This example has VT = -2V. Is VT here the Threshold voltage ? and if yes does it mean if I...
Hi Guys,
I am trying to use voltage comparator MAX9691 in my design. Basically the input signal is sinusoidal with peak of 200mV. So, I want to wire up this comparator in order to detect the pulse when it exceeds 20mV. The IC is 8-pins and very simple but I don't know how to set the reference...
Hi There,
Please help me, I just added polygon on a certain area on the board and suddenly some tracks somewhere completely away from I poured that polygon
went crazy and giving me error because of the track width. Also I tried to delete the track width rule and could not delete it. I tried to...
Hi Guys,
Thanks for the quick response,
I am relatively new to Altium and didn't know that there is no need to pour polygons on planes :)
Cheers,

Hi There,
I am designing 4-Layer PCB on Altium and having hard time in pouring polygon. Simply I have two internal planes for Vcc and GND and I want to pour polygons on each of them with the right net. But when I try to choose the right Layer which the polygon will be poured on I can not find...
Hi Crutschow,
Thanks for your reply
It is an analogue Sine wave. I can not really find any comparator with this high speed.
Do you know any comparator with this speed or response/delay time ?
Cheers,
Mourad
Hi There,
I am really confused between two parameters in the comparator. The Propagation delay and the Response time.
I understand that the Propagation delay is the delay from input to output of a digital gate switch and the Response time is how quickly a comparator changes output based on an...
