Sorry may be a trivial question...
Using an LT1997-3 as differential amplifier with G=1 how connect unused pins ?
thanks for help
I am evaluating an LT1997(-3) as a high-side current sense amp in a single-polarity system, up to 100+VDC.
I modeled it in LTSpice, and am seeing unexpected results.
The model doesn't seem to work with a single +5V supply, and gain configurations other…
I tried to make a circuit equation like the attached file because I didn't know what to put as Rp, Rn to verify the formula of note 9 in the data sheet.
Vos,out=（Vos x NOSEGAIN) + Ios x 22.5K + Ib x 22.5K x (1 - Rp/Rn)
However, the above formula…
Hi Harry and firstname.lastname@example.org,
As Harry is contemplating what could be a root cause, may I recommend the following steps to further isolate the issue:
1. Add an isolation resistor (e.g. 1k) between AD8237 output and LT1997 input to see if there is any…
I found one more device LT1997-2 seems to be suitable for my application (Slew rate 0.45 - 0.75 V/uS). If I set the gain 0.3
1. It is working fine for all input range and frequency of 10KHZ for Sine wave.
2. I can see Overshoot and undershoot…
We have a legacy power supply that has to be redesigned from the ground up. The input is 115 Volts, 400 Hz, four wire, three phase Wye connected. The desired output s a single DC voltage to feed downstream DC-DC converters, which will be designed separately…
The ADE7878 can be configured to accept multiple different configurations including 3 phase 4 wire and 3 phase 3 wire wye and delta. Our FAQ: AN-639 that is available on our website has detailed diagrams of each connection on pages 12…
Thanks for the reply and the suggestions. Those are fair guesses, however, despite my sloppy schematic: I am using a PCB layout for test hardware; I've checked for shorts/breaks/damaged components; I do have stable and working boost circuit on said hardware…
