Positive Supply Voltage. +2.7V to +5.25V.
Note: Bypass with a 0.1µF capacitor to GND.
Analog Input Channel 1 (AS1525) or Positive Analog Input (AS1524)
Analog Input Channel 2 (AS1525) or Negative Analog Input (AS1524)
Ground
External Reference Voltage Input. Sets the analog voltage range.
Note: Bypass with a 4.7µF capacitor to GND.
Conversion Start. A rising edge powers up the device and puts the track/
hold circuitry in track mode. At the falling edge of this pin, the device enters
hold mode and begins a conversion.
Note: This pin also selects the input channel (AS1525) or input polarity
(AS1524).
Serial Data Output. This pin transitions the falling edge of SCLK and goes
low at the start of a conversion and delivers the MSB at the completion of a
conversion.
Note: This pin goes high impedance once data has been fully clocked out.
Serial Clock Input. Clocks out data at DOUT with the MSB first.
