| This application note describes how to configure the PSoC® 3 and 5 IDACs as a flexible analog source. |
It presents different approaches for using the IDACs in applications and discusses the advantages and disadvantages of the topologies presented. This application note will: help you to understand compliance voltage and why it is important; explain how to generate an “any range” or “any ground” VDAC; describe an implementation for a multiplying VDAC; give details on how to build a rail-to-rail low output impedance 9-bit VDAC from a single IDAC, an OpAmp, and a resistor; and provide information on how to build a current scaling circuit with an OpAmp and two resistors.
