In your circuit, IN1 is being driven negative while the LTC1966 does not have a negative supply. In order to use LTC1966 on a single supply, use the circuit shown in the datasheet, Figure 9b.
Also, with a 250mVpk (500mVpp) sinusoid, the correct…
I have simulated using LTspiceXVII the LTC1966 RMS to DC converter for my application. But when tried to implement in reality it won't work in Lab. Below is the screen capture of how i tried to implement.
In reality when as soon as i power the IC…
Hi MB: The LTC1966 senses both DC and AC. You have 1.5V DC on the input, in addition to the 3Vpp AC, so you are overdriving the input. If you want an AC measurement, then you need to block DC. See Figure 9 in the datasheet.
But there are probably more…
Do you have a schematic that describes what you mean? Are you talking about tying the GND pin to a capacitor which is shunted to ground?
I need to use LTC1966 for one of my application.
My input has a DC value of 1.1V and has an ac of 0.355mv.(This is coming from a MEMS Microphone SPV1840LR5H-B from Knowles).
May I know how I simulate this circuit in LTSPICE. I don't know for…
