10 / 14 page 5. Digital-to-Analog (D/A) Converter These chips have built-in output operational amplifiers which use two independent on-chip D/A converters for CH1 and CH2. Both use dynamic level shift, combining resistance strings (R-string D/A conversion), pulse-width modulation (PWM D/A conversion) and level shift D/A conversion modes. (See figure below.) • Resistance String (R-string) D/A Converter This 9-bit D/A converter circuit has 512 (=29) unit resistors (R) connected in series so that a potential applied to both ends is subjected to 512-way division. The two adjoining potentials V2 and V1 of the divided potentials corresponding to the values of the 9 MSBs of data (D15 to D9) are sent via a switching circuit to the PWM D/A converter. At this point, V2 – V1 = (VH – VL)/512. No. 4624-10/14 LC78835K, 78835KM |
