27
WR
Write Input. Active LOW. Use to start a
new conversion and to select an analog
channel via address inputs A0, A1 and A2
in combination with CS.
28
BUSY
BUSY output goes LOW and stays LOW
during a conversion. BUSY rises when a
conversion is complete.
29
CLK
External Clock Input. The clock speed
determines the conversion rate by the
equation: f
CLK
= 16 f
SAMPLE
.
Read Input. Active LOW. Use to read the
data outputs in combination with CS. Also
use (in conjunction with A0 or A1) to place
device in power-down mode.
30
RD
31
CS
Chip Select Input. Active LOW. The
combination of CS taken LOW and WR
taken LOW initiates a new conversion and
places the outputs in tri-state mode.
32
V
SS
Voltage Supply Input. Nominally +5V.
Decouple to ground with a 0.1
μ
F ceramic
capacitor and a 10
μ
F tantalum capacitor.
PIN ASSIGNMENTS
PIN CONFIGURATION
ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from per-
formance degradation to complete device failure. Burr-
Brown Corporation recommends that all integrated circuits
be handled and stored using appropriate ESD protection
methods.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet
published specifications.
