_______________________________________________________________________________________
Typical Operating Characteristics (continued)
(VDD = +3.0V, VREF = 2.5V, 0.1F at REF, fSCLK = 2.17MHz, 16 clocks/conversion cycle (108ksps), CH- = GND for MAX145, TA = +25°C,
unless otherwise noted.)
Pin Description
External Reference Voltage Input. Sets the analog voltage range. Bypass with a 100nF capacitor close to
the device.
REF
5
Active-Low Chip-Select Input/Active-High Shutdown Input. Pulling CS/SHDN high puts the device into
shutdown with a maximum current of 5A.
CS/SHDN
6
Serial Data Output. Data changes state at SCLK’s falling edge. High impedance when CS/SHDN
is high.
DOUT
7
Serial Clock Input. DOUT changes on the falling edge of SCLK.
