Pin Desc ription
16
SSTRB
Serial-Strobe Output. In internal clock mode, SSTRB goes low when the MAX1112/
MAX1113 begin the A/D conversion and goes high when the conversion is complete.
In external clock mode, SSTRB pulses high for two clock periods before the MSB is
shifted out. High impedance when
CS
is high (external clock mode only).
20
V
DD
Positive Supply Voltage, +4.5V to +5.5V
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 serial interface. In external clock mode,
SCLK also sets the conversion speed (duty cycle must be 45% to 55%).
17
DIN
Serial-Data Input. Data is clocked in at SCLK’s rising edge.
12
13
REFOUT
AGND
Internal Reference Generator Output. Bypass with a 1μF capacitor to AGND.
Analog Ground
14
DGND
Digital Ground
Serial-Data Output. Data is clocked out on SCLK’s falling edge. High impedance when
CS
is high.
15
DOUT
10
SHDN
Three-Level Shutdown Input. Normally floats. Pulling
SHDN
low shuts the MAX1112/
MAX1113 down to 10μA (max) supply current; otherwise, the devices are fully opera-
tional. Pulling
SHDN
high shuts down the internal reference.
11
REFIN
Reference Voltage Input for Analog-to-Digital Conversion. Connect to REFOUT to use
the internal reference.
5–8
CH4–CH7
Sampling Analog Inputs
Ground Reference for Analog Inputs. Sets zero-code voltage in single-ended mode.
Must be stable to ±0.5LSB.
