DOUT
Serial Data Output. Data changes state at SCLK’s falling edge. DOUT is high impedance when
CS
is
high.
8
SCLK
3
SHDN
Three-Level Shutdown Input. Pulling
SHDN
low shuts the MAX1240/MAX1241 down to 15μA (max)
supply current. Both the MAX1240 and MAX1241 are fully operational with either
SHDN
high or float-
ing. For the MAX1240, pulling
SHDN
high enables the internal reference, and letting
SHDN
float dis-
ables the internal reference and allows for the use of an external reference.
4
REF
Reference Voltage for Analog-to-Digital Conversion. Internal 2.5V reference output for MAX1240;
bypass with 4.7μF capacitor. External reference voltage input for MAX1241, or for MAX1240 with the
internal reference disabled. Bypass REF with a minimum of 0.1μF when using an external reference.
7
CS
Active-Low Chip Select initiates conversions on the falling edge. When
CS
is high, DOUT is high
impedance.

Analog and Digital Ground
