Power Saving (continued)

The conversion time, tconv, is independent of the SCLK frequency. When operating the device at speeds lower

than the maximum rated throughput, the conversion time, tconv, does not change; the device spends more time in

power-down state. Therefore, as shown in Figure 76, the device power consumption from the AVDD supply and

the external reference source is directly proportional to the speed of operation. Extremely low AVDD power-down

current (50 nA, typical) and extremely low external reference leakage current (250 nA, typical), make this device

ideal for very low throughput applications (such as pulsed measurements).
