Single_supply_RS_232_interface_for_bipolar_A_D_converters

This circuit operates from a single 5-V supply, and draws a total quiescent current of about 37 mA. Figure 6-67B shows the operating sequence. The CS signal switches to a low state less than 1 μs after receiving the system clock, and the word can be transmitted after one cycle. After the 18 clock cycles required to complete conversion, the clock must shut off to allow CS to switch to a high state for at least 2 μs (minimum time between conversions). The operating sequence can then be repeated.
