For example, with V ref equal to 2.5 V, one LSB is 0.61 mV for a 12 bit ADC (ADS7829). (2) See the Typical Performance Curves for VCC = 5 V and Vref = 5 V. (3) The maximum clock rate of the ADS7826/27/29 are less than 1.2 MHz at 2 V ≤V CC <2.7 V. The recommended regerence voltage is between 1.25 V to 1.024 V. 3 |
