PIN ASSIGNMENT
Pin 1 —No Connection —This pin is not internally
connected.
Pin 2 — IN1 — 0V to 10V Analog Input. Connected
to AGND for 10V range.
Pin 3 — IN2 — 0V to 5V Analog Input. Connected
to AGND for 5V range.
Pin 4 — VREF – Internal Voltage. Reference Output.
Pin 5 — AGND — Analog Ground. Connect to
pin 16 at the device.
Pin 6 — D11 — Data Bit 11. Most Significant Bit
(MSB).
Pin 7 — D10 — Data Bit 10.
Pin 8— D9 — Data Bit 9.
Pin 9 — D8 — Data Bit 8.
Pin 10 — D — Data Bit 7 if HBE is LOW; LOW if
7
HBE is HIGH.
Pin 11 — D — Data Bit 6 if HBE is LOW; LOW if
6
HBE is HIGH.
Pin 12 — D5 — Data Bit 5 if HBE is LOW; LOW if
HBE is HIGH.
Pin 13 — D4 — Data Bit 4 if HBE is LOW; LOW if
HBE is HIGH.
Pin 14 —N.C.—This pin is not internally connected.
Pin 15 —N.C.—This pin is not internally connected.
Pin 16— DGND — Digital Ground. Connect to
pin 5 at the device.
Pin 17 — D — Data Bit 3 if HBE is LOW; Data Bit
3
11 if HBE is HIGH.
Pin 18 — D2 — Data Bit 2 if HBE is LOW; Data Bit
10 if HBE is HIGH.
Pin 19— D — Data Bit 1 if HBE is LOW; Data Bit
1
9 if HBE is HIGH.
Pin 20 — D0 — Data Bit 0 if HBE is LOW. Least
Significant Bit (LSB). Data Bit 8 if HBE is HIGH.
Pin 21 — HBE — High Byte Enable, When held
LOW, data output as 12-bits in parallel. When
held HIGH, four MSBs presented on pins 17–
20, pins 10 – 13 output LOWs. Must be LOW to
initiate conversion.
Pin 22— R/C — Read/Convert. Falling edge initiates
conversion when CS is LOW, HBE is LOW, and
BUSY is HIGH.
Pin 23 — CS — Chip Select. Outputs in Hi-Z state
when HIGH. Must be LOW to initiate conversion or
read data.
Pin 24 — BUSY — Output LOW during
conversion. Data valid on rising edge in Con-
vert Mode.
Pin 25 — N.C. — This pin is not internally connected.
Pin 26 — VSD — Positive Digital Power Supply, +5V.
Connect to pin 27, and bypass to DGND.
Pin 27 — V — Positive Analog Power Supply.
SA
+5V. Connect to pin 26, and bypass to AGND.
Pin 28 — N.C. — This pin is not internally connected.
