Feb 25, 2016 · Hello folks, I have been making this clamp on current probe with Hall sensor and it gives me an output of 1mV/Amp. The problem I have is the amplification of the signal. The purpose is to measure currents in the order of 1-50 amps changing at a speed of about 1000Hz. I have connected a AD623...

Jun 23, 2014 · I guess you know the AD623 is a differential input amplifier. For a Gain of say 100, the highest Vin diff would be ~35mV. I use the AD623 for weigh scale bridges, powered by 5V and the best I can get is around 3.5V. I use a R2R OPA after the AD623 to bring the Vout upto around 4.096V, which drives a 12 bit ADC.

Jul 17, 2021 · This is a common configuration. My students do an investigation using a strain-gauge and an AD623. They use 0.5 to 4.5v output, avoiding the rail issue, and use REF to set bridge zero as 2.5v so the output swings either way +/- 2v. The ADC is 0 - 5v but only 0.5 - …

Oct 17, 2020 · REF of AD623 is connected to a 10k POT between Gnd and +vs, this was my attempt at adjusting the offset of the reading. Click to expand... Connecting the REF input of an instrumentation amp to a resistive source messes up the common-mode rejection of the device.

Jun 9, 2023 · Hi, I need to compare two LDR value with a AD623. The ouput of the AD623 will be connected to an arduino Since the output voltage could be negative, how to manage that with arduino ?. thx

Apr 5, 2018 · I use the AD623 in a number of projects, I could never get reliable results when the Vs was less than 4.5V. I see that you have a 2.4V voltage splitter for +/-1.2V for the AD623 Vref [pin 5]. So with no VG1 input [shorted] what is the DC level of the AD623 output pin #6. It should be approx +1.2V Also the DC levels of theOPA2350's ? E

Mar 7, 2014 · If you look at the OUTPUT section of the AD623 data sheet SPECIFICATIONS table you will see that the minimum output voltage with a single supply is 0.01V (10mV) as you measured. If you want the output to be at some other voltage at null and allow positive or negative excursions from there, then you can connect a voltage to pin 5.
