RD
I
Read Input. Active LOW. Reads the data
outputs in combination with CS.

AIN1
I
Analog Input Channel 1
3
AIN2
I
Analog Input Channel 2
21
CS
I
Chip Select Input. Active LOW. The
combination of CS taken LOW and WR
taken LOW initiates a new conversion and
places the outputs in the tri-state mode.

Reference Voltage Input
22
WR
I
Write Input. Active LOW. Starts a new
conversion and selects an analog channel
via address inputs A0 and A1, in
combination with CS.

BUSY
O
BUSY goes LOW and stays LOW during a
conversion. BUSY rises when a conversion
is complete and enables the parallel outputs.

CLK
I
External Clock Input. The clock speed
determines the conversion rate by the
equation fCLK = 16*fSAMPLE.
