NAME
I/EREF
2
BIT
1 = internal reference, 0 = external reference. Internal reference selects +2.048V (MAX1108) or
+4.096V (MAX1109), or an external reference can be applied to the REF pin.
DESCRIPTION
I/ECLK
3
START
1 = external clock, 0 = internal clock. The SAR can be driven by the internal oscillator, or with the
SCLK signal.
SHDN
0 (LSB)
7 (MSB)
1 = operational, 0 = power down. For a full power down set REFSHDN = SHDN = 0. (See Power-
Down Mode section.)
The first logic “1” bit after CS goes low defines the beginning of the control byte.
SEL2
SEL1
SEL0
6

4
Selects the mode of operation (Table 2).
REFSHDN
1
1 = operational (if I / EREF = 1), 0 = reference shutdown. When using an external reference, power
consumption can be minimized by powering down the internal reference separately (I / EREF = 0).
REFSHDN must be set to 0 when SHDN = 0.
