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 15A (max)
supply current. Both the MAX1240 and MAX1241 are fully operational with either SHDN high or
unconnected. For the MAX1240, pulling SHDN high enables the internal reference, and letting SHDN
open disables 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 4.7F capacitor. External reference voltage input for MAX1241, or for MAX1240 with the
internal reference disabled. Bypass REF with a minimum of 0.1F 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.
5
GND
Analog and Digital Ground
2
AIN
Sampling Analog Input, 0V to VREF range

VDD
Positive Supply Voltage: 2.7V to 3.6V, (MAX1240); 2.7V to 5.25V (MAX1241)
PIN
Serial Clock Input. SCLK clocks data out at rates up to 2.1MHz.
