Published Date: 08/31/2004

Description

Unbuffered multiplexed ratiometric analog-to-digital converters have strict requirements on driving source impedance which are not always obvious. This application report addresses the trade-offs between source impedance and sample rate. It includes examples using the TMS470R1x family of processors in the TSC5000 process node (F10/C10). With adjustments to maximum clock rates this application no
