  • Input multiplexer provides two differential or four single-ended inputs
  • Internal Low drift voltage reference, oscillator and PGA
  • Programmable Comparator
  • Uses I2C 7-bit addresses between 0x48-0x4B (selectable with jumpers)
  • Operating Temperature: -40C to +125C
  • Works with Raspberry Pi and Arduino.
  • Pinout:
    • V: VCC power
    • G: GND ground
    • SCL: Clock
    • SDA: Data
    • ADDR: Address pin (not necessary for normal use)
    • ALERT: Alert pin (not necessary for normal use)
    • A0: Analog Input 0
    • A1: Analog Input 1
    • A2: Analog Input 2
    • A3: Analog Input 3
  • I2C Address Hookup: (to select between the 4 addresses if you want to use 2 to 4 at the same time just set each one to a different address with the hookups as shown below)
    • To set your board's address to 0x48: Connect ADDR pin to GND
    • To set your board's address to 0x49: Connect ADDR pin to VDD
    • To set your board's address to 0x4A: Connect ADDR pin to SDA
    • To set your board's address to 0x4B: Connect ADDR pin to SCL
  • ALERT pin goes HIGH if an input voltage exceeds the threshold level. Can be used in comparator mode.
