12.2 Analog Mode Programming
The analog output can be configured in many ways:
It consists of three major building blocks,
In the default configuration (all OTP bits = 0), the analog output is set for 360° operation, internal DAC reference
(VDD5V/2), external OPAMP gain, 0-100% ratiometric to VDD5V.
Shown below is a typical example for a 0°-360° range, 0-5V output. The complete application requires only one external
component, a buffer capacitor at VDD3V3 and has only 3 connections VDD, VSS and Vout (connectors 1-3).
Note: the default setting for the OPAMP feedback path is:FB_intEn=0=external. The external resistors Rf and Rg must be
installed. In the programmed state (FB_intEn=1=internal), these resistors do not need to be installed as the feedback
path is internal (Rf_int and Rg_int).
