F Tantalum. Buffer for external loads.
Analog Ground. Connect to pin 13.
Data Bit 11. Most Significant Bit (MSB).
Data Bit 10.
Data Bit 9.
Data Bit 8.
Data Bit 7 if HBE is LOW; LOW if HBE is HIGH.
Data Bit 6 if HBE is LOW; LOW if HBE is HIGH.
Data Bit 5 if HBE is LOW; LOW if HBE is HIGH.
Data Bit 4 if HBE is LOW; LOW if HBE is HIGH.
Digital Ground. Connect to pin 4.
Data Bit 3 if HBE is LOW; Data Bit 11 if HBE is HIGH.
Data Bit 2 if HBE is LOW; Data Bit 10 if HBE is HIGH.
Data Bit 1 if HBE is LOW; Data Bit 9 if HBE is HIGH.
Data Bit 0 if HBE is LOW. Least Significant Bit (LSB);
Data Bit 8 if HBE is HIGH.
High Byte Enable. When held LOW, data output as 12-
bits in parallel. When held HIGH, four MSBs presented on
pins 14-17, pins 9-12 output LOWs. Must be LOW to
initiate conversion.
Read/Convert. Falling edge initiates conversion when CS
is LOW, HBE is LOW, and BUSY is HIGH.
Chip Select. Outputs in Hi-Z state when HIGH. Must be
LOW to initiate conversion or read data.
Busy. Output LOW during conversion. Data valid on rising
edge in Convert Mode.
Negative Power Supply. –12V or –15V. Bypass to GND.
Positive Digital Power Supply. +5V. Connect to pin 24,
and bypass to GND.
Positive Analog Power Supply. +5V. Connect to pin 23,
and bypass to GND.
