ADS1262: ADS1262 4 ANALOG USE

GANESH JOSHI
Prodigy 20 points
Part Number: ADS1262

HELLO 

I AM PLC USER I NEED 32 BIT RESOLUTION ANALOG INPUT.  BUT DONT HAVE MODULE FOR THAT, I WANT TO USE ADS1262 AND SEND DATA TO PLC BY SERIAL PORT.

I WANT TO USE ADS1262 WITH ARDUINO . MY APPLICATION IS I WANT TO MEASURE 4 ANALOG INPUT RANGE  0~5V. KINDLY HELP HOW TO CONNECT ARDUINO TO ADS1262 WITH ANALOG INPUT CONNECTION.

REGARDS

    Hi GANESH,

    We will get it back to you soon,thanks for your patience.I have two questions:

    1. Is your signal single-ended? just confirm.
    2. Is your Arduino is Uno or other version? Which microcontroller are you using? ATmega328P or others?

    Regards,

    Dale

    Hi Dale

    Thanks for your reply. 

    1:- Yes signal is single-ended.

    2:- Right now i am using uno, but will use if you suggest any other.

    regards

    Hi Ganesh,

    The microcontroller on Arduino UNO (ATmega168) only has one SPI interface (ATmega328 on Arduino UNO R3 is pin-pin compatible with ATmega168 and has more memory), the digital connection depends on how you want to control and communicate the ADC, below is an example: 

    ATmega168           ADS1262

    Pin 13 SCK   <->   Pin 11 SCLK

    Pin 12 MISO   <->  Pin 13 DOUT 

    Pin 11 MOSI   <->   Pin 12 DIN

    Pin 10 SS (or GPIO)    <->   Pin 10 /CS

    Other GPIO    <->   Pin 9 START

    For analog connection, any analog input pin can be used for your signal measurement, please refer to the Single-Ended Measurement section in datasheet (page 107). Note that your single-end signal plus the level shift voltage must be within the ADC specified operating range.

    Regards,

    Dale
