8-Channel 12-Bit 200ksps ADC Data Acquisition Shield for Arduino

   

ARD-LTC1863

The ARD-LTC1863 is an Arduino compatible shield that contains a Linear Technology LTC1863 12-Bit, 8-Channel, 200ksps ADC. It can be configured to measure 8 single-ended voltages, 4 differential voltages, or any other combination.  The onboard EEPROM can be used to store calibration and configuration information directly on each ARD-LTC1863 board.  A 6-byte EUI-48TM-compatible globally unique ID number is also provided. The ARD-LTC1863 can be used with other Arduino shields to make a simple, yet quite versatile, data acquisition system.

For a higher resolution (16-bit) version of this shield, please see the ARD-LTC1867.

Features

  • 12-bit, 200ksps ADC
  • 8 single-ended channels, 4 differential channels, or any combination
  • Optional onboard 5V linear regulator provides clean power to the ADC
  • 128 bytes of onboard EEPROM for storing configuration or calibration values
  • Read-only 6-byte EUI-48TM-compatible globally unique ID
  • Arduino form factor and software library
  • I2C interface

Compatible Arduino Boards

The ARD-LTC1863 uses the programming header for the SPI wires (MISO, MOSI, SCLK), D3 for /CS to operate the ADC, and the two TWI/I2C pins (SCL and SDA on modern r3 boards, A4/A5 on previous designs) for the EEPROM. Please check carefully for pin conflicts.

Most standard form factor Arduino or compatible boards with 5V I/O should work with the ARD-LTC1863.  This includes the Arduino Uno, Arduino Mega, and Arduino Ethernet.  The Arduino Leonardo uses pin D3 as the TWI/I2C SCK pin, and thus JP6 must be set to use D8 as the chip select line.

The normal ARD-LTC1863 is not compatible with Arduinos using 3.3V I/O, such as the Due, Zero, etc.  This is because the LTC1863 requires a 5V supply to deal with the 4.096V reference voltage.   Please contact us about options for 3.3V compatibility.

The Arduino Mini, Micro, and Nano, do not provide the standard Arduino header connectors and thus cannot be directly used with the ARD-LTC1863.

Data Acquisition Arduino Shields

After developing several products focused on data acquisition, like the MRBW-RTS and a few currently in development like the MRB-DCCM (DCC Meter) and MRBW-DAQ (Data Acquisition node), we realized some of the ICs used in those designs would be useful on their own.  To enable rapid development with these ICs, a series of ArduinoTM shields was created allowing you to easily implement a wide variety of data acquisition applications.
