5-Bit Voltage Reference Digital-to-Analog Converter
(VREF_DAC)
4.1
4.1.1 Overview
The 5-bit VREF_DAC is 32-tap resistor ladder network that provides a selectable voltage
reference for applications that need a voltage reference. The 32-tap resistor ladder
network divides the supply reference V
input selects the output voltage level, which varies from V
4.1.2 Features
Features of the 5-bit VREF_DAC include:
Freescale Semiconductor
• 5-bit resolution
• Power down mode to conserve power when it is not being used
• Output that is internally routed to internal analog comparator positive input 0
• Ability to remain operating in STOP mode
• 5bDACAO is internally routed to CMPA_P0
• 5bDACBO is internally routed to CMPB_P0
• 5bDACCO is internally routed to CMPC_P0
