10-Bit Analog Digital Converter (ADC1)
24.1
Features
The principal features of the ADC1 are:
• Up to 8 analog input channels (channel 7 reserved for future use)
• Flexible results handling
- 8-bit and 10-bit resolution
• Flexible source selection due to sequencer
- insert one exceptional sequence (ESM)
- insert one interrupt measurement into the current sequence (EIM), single or up to 128 times
- software mode
• Conversion sample time (separate for each channel) adjustable to adapt to sensors and reference
• Standard external reference (VAREF) to support ratiometric measurements and different signal scales
• DMA support, transfer ADC conversion results via DMA into RAM
• Support of suspend and power saving modes
• Result data protection for slow CPU access (wait-for-read mode)
• Programmable clock divider
• Integrated sample and hold circuitry

Introduction
The TLE9869QXA20 includes a high-performance 10-bit Analog-to-Digital Converter (ADC1) with eight
multiplexed analog input channels. The ADC1 uses a successive approximation technique to convert the analog
voltage levels from up to eight different sources. The analog input channels of the ADC1 are available at AN0,
AN2 - AN5.
