First 16-Bit ADC in a SOT-23 package. 2. High Throughput with Low Power Consumption 3. Flexible Power/Serial Clock Speed Management The conversion rate is determined by the serial clock allowing the conversion time to be reduced through the serial clock speed increase. This allows the average power consumption to be reduced when a powerdown mode is used while not converting. The part also features a shutdown mode to maximize power efficiency at lower throughput rates. Power consumption is 0.5µA max when in shutdown. 4. Reference derived from the power supply. 5. No Pipeline Delay The part features a standard su...
