Pin Description Pin Number Pin Name Description 1 VDD Positive Supply Voltage. +2.7V to +5.25V. Note: Bypass with a 0.1µF capacitor to GND. 2AIN1/AIN+ Analog Input Channel 1 (AS1525) or Positive Analog Input (AS1524) 3AIN2/AIN- Analog Input Channel 2 (AS1525) or Negative Analog Input (AS1524) 4GND Ground 5REF External Reference Voltage Input. Sets the analog voltage range. Note: Bypass with a 4.7µF capacitor to GND. 6 CNVST 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). 7DOUT 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. 8SCLK Serial Clock Input. Clocks out data at DOUT with the MSB first.
