NAME
FUNCTION
12
REFADJ
Input to the Reference-Buffer Amplifier. To disable the reference-buffer amplifier, connect REFADJ to
VDD.
13
AGND
Analog Ground. Also IN- Input for single-ended conversions.
14
DGND
Digital Ground
15
DOUT
Serial Data Output. Data is clocked out at the falling edge of SCLK. High impedance when
CS is high.
16
SSTRB
Serial Strobe Output. In internal clock mode, SSTRB goes low when the MAX186/MAX188 begin the
A/D conversion and goes high when the conversion is done. In external clock mode, SSTRB pulses
high for one clock period before the MSB decision. High impedance when
CS is high (external mode).
17
DIN
Serial Data Input. Data is clocked in at the rising edge of SCLK.
18
CS
Active-Low Chip Select. Data will not be 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 40% to 60% in external clock mode.)
