Analog Inputs
9
COM
Common Input. Negative analog input in single-ended mode. COM sets zero-code voltage in
unipolar and bipolar mode.
10
SHDN
Active-Low Shutdown Input. Pulling SHDN low shuts down the device reducing supply current
to 0.2A. Driving shutdown high enables the devices.
11
REF
Reference-Buffer Output/ADC Reference Input. Reference voltage for analog-to-digital
conversion. In internal reference mode, the MAX1146/MAX1148 VREF is +4.096V, and the
MAX1147/MAX1149 VREF is +2.500V.
12
REFADJ
Bandgap Reference Output and Reference Buffer Input. Bypass to AGND with a 0.01F
capacitor. Connect REFADJ to VDD to disable the internal bandgap reference and reference-
buffer amplifier.
13
AGND
Analog Ground
14
DGND
Digital Ground
15
DOUT
Serial Data Output. Data is clocked out at the falling edge of SCLK when CS is low. DOUT is
high impedance when CS is high.
16
SSTRB
Serial Strobe Output. In internal clock mode, SSTRB goes low when the ADC conversion
begins, and goes high when the conversion is finished. In external clock mode, SSTRB pulses
high for two clock periods before the MSB decision. SSTRB is high impedance when CS is high
(external clock mode).
17
DIN
Serial Data Input. Data is clocked in at the rising edge of SCLK when CS is low. DIN is high
impedance when CS is high.
18
CS
Active-Low Chip Select. Data is not clocked into DIN unless CS is low. When CS is high, DOUT
is high impedance.
19
SCLK
Serial Clock Input. Clocks data in and out of the serial interface and sets the conversion speed
in external clock mode. (Duty cycle must be 40% to 60%.)
20
VDD
Positive Supply Voltage. Bypass to AGND with a 0.1F capacitor.

N.C.
No Connection. Not internally connected.
