NOTES: 8. The conversion rate is 8 kHz; the out-of-band measurement is made from 4400 Hz to 3 MHz.
9. The digital input to the DAC channel at DIN is in 2’s complement format. The TLC320AD56C is a current
DAC and requires a load resistor for current-to-voltage conversion. This output voltage is across the load
resistor (see Figures 5–1 and 5–2).
