Hi guys
What the different between
LF412ACN/NOPB and LF412CN/NOPB ?
Shown in the link below
**broken link removed**
I want to get a LF412 test on breadboard
Hope you guys can help me
Thanks
hi,
looking at the d/s, the LF412A has a 'better' specification than the LF412.
Lower offset, higher working voltage and the d/s says the LF412A is 100% tested for performance compared to the LF412 which is only batch sampled.
The section depends on the circuit you are building, what is it.?
hi,Hi,
Thanks for your reply..
I want to build an ECG Front End
An Instrumentation amplifier IC is used for the front end of an ECG circuit because its amplifiers and circuit resistors are extremely well-matched for very good common-mode interference rejection. Here is an example using an AD620A instrumentation amplifier IC:
hi,
Use an Instrumentation amplifier for the ECG front end.
You need a high CMMR for an ECG in order to cancel out unwanted signals.
It is a lowpass shelving filter. Calculate the capacitor value for whatever cutoff frequency you want.If base on your circuit what the value for C1, capacitor value?
Make it yourself with whatever parts you want to use.High pass filter circuit?
Use a battery to power the circuit so that it has isolation from the mains to avoid electrocuting the patient if something shorts.built patient/circuit protection/isolation?
