The conversion rate is determined by the SCLK.PRODUCT HIGHLIGHTS 10-/12-bit ADCs in SC70 and MSOP packages. Low power consumption. 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 power-down mode is used while not converting. The part also features a power-down mode to maximize power efficiency at lower throughput rates. Current consumption is 1 μA maximum and 50 nA typically when in power-down mode. Reference derived from the power supply. No pipeline delay.
