Description
1–6
BIT 11-BIT 16
DO
BIT 11–BIT 16 represent the six LSBs of data.
7
BUSY
DO
Status Line for Converter. Active HIGH, indicating a conversion or calibration in progress.
BUSY should be buffered when capacitively loaded.
8
CAL
DI
Calibration Control Pin (Asynchronous).
9
SAMPLE
DI
VIN Acquisition Control Pin. Active HIGH. During conversion, SAMPLE controls the state
of the internal sample-hold amplifier and the falling edge initiates conversion (see “Conver-
sion Control” paragraph). During calibration, SAMPLE should be held LOW. If HIGH dur-
ing calibration, diagnostic information will appear on the two LSBs (Pins 5 and 6).
10
CLK
DI
Master Clock Input. The AD676 requires 17 clock cycles to execute a conversion.
11
DGND
P
Digital Ground.
12
VCC
P
+12 V Analog Supply Voltage.
13
AGND
P/AI
Analog Ground.
14
AGND SENSE
AI
Analog Ground Sense.
15
VIN
AI
Analog Input Voltage.
16
VREF
AI
External Voltage Reference Input.
17
VEE
P
–12 V Analog Supply Voltage. Note: the lid of the ceramic package is internally connected to
VEE.
18
VDD
P
+5 V Logic Supply Voltage.
19–28
BIT 1–BIT 10
DO
BIT 1–BIT 10 represent the ten MSB of data.
Type: AI = Analog Input
DI = Digital Input
DO = Digital Output
