10 / 30 page 10 AVR32768 32157A-AVR-12/10 Table 7-2. ADC single-ended external voltage reference, 3.3V power supply mode. Signal name Recommended pin connection Description ADCREF0 1.0V to 2.6V Single-ended external voltage reference ADCREF1 1.0V to 2.6V Single-ended external voltage reference Figure 7-2. Single-ended external reference, 5V power supply mode. ADCREF0 ADCREF1 DC/DC converter 1.0 to 3.5 V DC/DC converter 1.0 to 3.5 V Table 7-3. ADC single-ended external voltage reference, 5V power supply mode. Signal name Recommended pin connection Description ADCREF0 1.0V to 3.5V Single-ended external voltage reference ADCREF1 1.0V to 3.5V Single-ended external voltage reference 7.2.2 ADC differential external reference pins (ADCVREFP/ADCVREFN) In order to use the internal 1V bandgap reference, the ADCVREFP and ADCVREFN pins must be used with decoupling capacitors (see Figure 7-3 and Table 7-5 for typical values). If the internal voltage reference is unused, ADCVREFP and ADCVREFN can be used as differential external voltage reference (see Figure 7-4 and Table 7-5). Figure 7-3. ADCVREFP/ADCVREFN external decoupling for use of internal bandgap reference. Table 7-4. ADC differential external voltage reference, internal reference used. Signal name Recommended pin connection Description ADCVREFP Positive differential voltage Differential external voltage reference ADCVREFN Negative differential voltage Differential external voltage reference |
