Description

Positive Supply Voltage. +2.7 to +5.25V.

Note: Bypass with a 0.1µF capacitor to GND.

Analog Input Channel 1 (AS1529) or Positive Analog Input (AS1528)

Analog Input Channel 2 (AS1529) or Negative Analog Input (AS1528)

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 (AS1529) or input polarity

(AS1528).

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.
