ADS1015EVM: Pin assignment on the EVKIT

Part Number: ADS1015EVM

Hi,

Some questions from a beginner who started it's first steps, please assume that I would like to work only with 5V DC:

  1. The pin numbering on J2A is not clear enough for me, where is '1' and where is '10' on the board? Where to connect the 5VDD and where the GND there?
  2. Assuming that the we actually would like to connect only to AN0 and we are going to use the 1015, which one of the AN0 we should make the connection? U1 or U2?
  3. The analog device needs to a reference power supply of 5V, is it ok to connect it to pin '4' on JMP2.
  4.  Should I change any Jumper if working with 5V or only to take the 'S1' to the center position?

Thx

Neta

    Hello Neta,

    the User guide for the ADS1015EVM will be helpful to refer to for these questions. 

    1. The PCB has a pin one indicator as part of the silkscreen on the PSB. For headers, this can be a number label or connection (ex 1, Va), or a corner missing around the header silkscreen, or a square to go around the pin. As for the EVM, I believe pin 1 would be the bottom left pin. 

    2. The header J1 has all connections to the input channels, U1, AIN0 is connected to J1-2, and U2 AIN0 is connected to J1-10. If you do not know if ADS1015 is on the board, look on the silkscreen of the board to see which device is checked. Also each device has the part number scripted on it on top, magnifying glass can be used to read it. 

    3. Yes you can use JMP2-4 to provide a voltage to VDD1 net. Be sure that no other sources are connected to the same net through out headers. Also, JMP1 is provided to used to provide voltage signals. JMP2 is meant to configure the address pin of the device. 

    4. S1 in the center position will provide 5V to the board circuitry. be sure to use the same net that 5V is connected through JMP1 on the board. 

    Regards
