    我看了AD737的手册,英文半懂半不懂,看输出口是输出伏电压?

  • AD737 - negative output voltage swing?

    Hello,

    I'm having trouble understanding the AD737 datasheet:

    On page 4 it says:

    Output characteristics:

    [....]

    Conditions:

    no load; +Vs=5V; -Vs=-5V

    [...]

    Output Voltage Swing = -3.4V

    Why is the output voltage swing negative? Is the output…

  • RE: AD736 input amplitude for 32kHZ

    Hello,

    Thanks for your question. 200mV is fine for 32kHz, refer to data sheet figures 4 and 5 which display response vs. frequency. Note that the output is negative for the AD737, if you need positive use the AD736 - same part with a built-in inverter…

  • RE: AD8436 RMS-to-DC

    Hi JS,

    I've now built the AD8436 RMS-TO-DC converter module for evaluation. I've been "parallel" comparing it against the AD737 module.

    The AD737 appears to work correctly. It does require a trimpot adjustment on the Cc pin (pin-1…

  • RE: AD736 behaviour in multisim

    Hi Jino,

    Looks better.

    Sorry our intranet is really slow this am, you're using the AD736, I said AD737 in my previous response.

    The schematic looks better. You have ac coupled pin 2, however pins 1 and 2 are both inputs, and one or the other must…

  • AD736 Application Design

    Hi I am bit new with RMS to DC converter. I try to use AD737 but found out put of it is  -VE. So, decide to use

    AD736. My application is reading  AC signal from 3 Phase voltage ( between 0.5V to 2V at 50Hz/60HZ). Need fast satelliting time( under 10mS…

  • What is an rms-dc converter?

    An rms-dc converter is a special linear circuit that computes the rms (i.e. heating value) of an ac waveform to an exact dc voltage having the same value

  • AD736ARZ

    I want to measure the true rms value on the load in an application in which we perform phase angle control.

    Is it possible to see true rms with this chip as a proportional dc voltage?

    Thanks ,

  • RE: RMS Value of AD8436

    Hi Christian,

    1. I once spent some time working with the linearity characteristic of the AD737, a low cost low current rms-dc. The customer had the same issue with the part, so I looked at a way to compensate over a wide voltage range. I took data for…

  • RE: Query Regarding AD736...

         Hi,

         First of all, it's good you're using a transformer -- this is the safest way to measure around power lines!

         The AD736 is designed primarily for dual supply operation -- its inputs and outputs cannot go all the way down to -Vs (in other…
