Featured Circuit From the Lab

Circuits From the LabCN0312 Circuit Note: Dual-Channel Colorimeter with Programmable Gain Transimpedance Amplifiers and Synchronous Detectors. The circuit measures the ratio of light absorbed by the sample and reference containers at three different wavelengths. It demonstrates an efficient solution for many chemical analysis and environmental monitoring instruments used to measure concentrations and characterize materials through absorption spectroscopy.
