Amplificador de instrumentação DIY com 3 OpAmps - Ajustando o CMRR ----------------------------------------- DIY Instrumentation Amplifier with 3 OpAmps - Trimming the CMRR Consider R3, R4, R5 and R6 as 27k, 10%. The CMRR will be affected by the resistors tolerance. Adding Rtrim1 and Rtrim2 is possible to improve the CMR. R4 is a value below and will be compensated by the trim resistors. Prof. Haroldo Amaral
