Chip Select Input. CS must be low for the device to be selected or to recognize the RD input.
Read Input. RD must be low to access data. RD is also used to start conversions. See the
Microprocessor Interface section.
Test Point. Connect to V
Mode Input. MODE = low puts the ADC into its asynchronous conversion mode. MODE has to be
tied high for the synchronous conversion mode and the ROM interface mode.
BUSY Output. BUSY going low indicates the start of a conversion. BUSY going high indicates the
end of a conversion.
External Clock Input/Internal Oscillator Pin for frequency setting RC components.
