Function
Analog input 3.
Analog input 4.
Analog input 5.
Analog input 6.
Analog input 7.
Start of conversion. Active high digital input pulse initiates conversion.
End of conversion. This output goes low after a START pulse occurs, stays
low for the entire A/D conversion, and goes high after conversion is
completed. Data on DB0–DB7 is valid on rising edge of EOC and stays valid
until next EOC rising edge.
Data output 3.
Output enable input. When OE = 0, DB0–DB7 are in high impedance state;
OE = 1, DB0–DB7 are active outputs.
Clock. Clock input provides timing for A/D converter, S/H, and digital
interface.
Positive supply. 5V ±10%.
Positive reference voltage.
Ground. 0V, all analog and digital inputs or outputs are referenced to this
point.
Data output 1.
Data output 2.
Negative reference voltage.
Data output 0.
Data output 4.
Data output 5.
Data output 6.
Data output 7.
Address latch enable. Input to latch in the digital address (ADDR2-0) on the
rising edge of the multiplexer.
Address input 2 to multiplexer. Digital input for selecting analog input.
Address input 1 to multiplexer. Digital input for selecting analog input.
Address input 0 to multiplexer. Digital input for selecting analog input.
Analog input 0.
Analog input 1.
Analog input 2.
