Figure 4 shows the MAX11100 in its simplest configura- tion. The serial interface requires only three digital lines (SCLK, CS, and DOUT) and provides an easy interface to microprocessors (FPs). The MAX11100 has two power modes: normal and shut- down. Driving CS high places the MAX11100 in shut- down, reducing the supply current to 0.1FA (typ), while pulling CS low places the MAX11100 in normal operating mode. Falling edges on CS initiate conversions that are driven by SCLK. The conversion result is available at DOUT in unipolar serial format. The serial data stream consists of eight zeros followed by the data bits (MSB first). Figure 3 shows the interface timing diagram. Analog Input Figure 5 illustrates the input sampling architecture of the ADC. The voltage applied at REF sets the full-scale input voltage. Track-and-Hold (T/H) In track mode, the analog signal is acquired on the inter- nal hold capacitor. In hold mode, the T/H switches open and the capacitive DAC samples the analog input. Figure 1.
