Instrumentation Amplifier with CMRR Calibration

Common mode rejection ratio (CMMR) is one parameter that specify the instrumentation performance. LM4250 is high performance op-amp which is characterized by very low power consumption. With special arrangement as shown in the following schematic diagram, the instrumentation amplifier circuit will be featured with calibration to maximize the CMMR performance.  

AD532 Multiplier IC and Its Pin Configurations

The AD532 is the first pre-trimmed single chip monolithic multiplier/divider. This device guarantees a maximum multiplying error of +- 1% and a +-10 V output voltage without the need for any output op amp or external trimming resistors. It’s simplicity of use provides design engineers with an attractive alternative to modular multipliers because the AD532 …
