PRODUCTION DATA.
The ADC has a set of internal registers that can be accessed by the serial interface formed by the SEN (serial interface enable), SCLK (serial interface clock), SDIN (serial data input data), and SDOUT (serial data output) pins. Serially shifting bits into the device is enabled when SEN is low. SDIN serial data are latched at every SCLK rising edge when SEN is active (low). Data can be loaded in multiples of 24-bit words within a single active SEN pulse. The first 16 bits form the register address and the remaining eight bits are the register data. The interface can work with SCLK frequencies from 10 MHz down to very low speeds (of a few hertz) and also with a non-50% SCLK duty cycle.
