2.3 TI Precision Labs - Switches and Muxes: Leakage Current and Charge Injection


July 19, 2016

This TI Precision Labs - Op Amps training video provides an overview of leakage current and charge injection. Specifically, we will see how leakage current can cause offset errors in high input impedance data acquisition systems and how charge injection introduces output voltage error when multiplexer switches are turned on or off. The goal of this series is to understand the DC performance parameters of multiplexers and how they affect data acquisition system performance. The multiplexer highlighted in this video series is the MUX36S08.
