I have a weighing scale project using a 200kg load cell with a rated output of 1mV/V. I used 5V as excitation voltage and an Ad620 in-amp for my amplifier. I only need atleast the 0-100kg so I only... The AD620 is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000. Furthermore, the AD620 features 8-lead SOIC and DIP packaging that is smaller than discrete designs and offers lower power (only 1.3 mA max supply current), making it a good fit for battery powered, portable (or remote) applications. A single external resistor sets any gain from 1 to 10,000. The INA128 provides anindustry-standard gain equation; the INA129 gain equation is compatible with the AD620. The INA12x is available in 8-pin plastic DIP and SO-8 surface-mount packages, specifiedfor the –40°C to +85°C temperature range.
