8-Channel 16-Bit 200ksps ADC Data Acquisition Shield for Arduino

   

ARD-LTC1867

The ARD-LTC1867 is an Arduino compatible shield that contains a Linear Technology LTC1867A 16-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-LTC1867 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.

Features

  • 16-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-LTC1867 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 should work with the ARD-LTC1867.  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.  Additionally, onboard level shifters for the SPI I/O lines are now included, so Arduino boards using 3.3V I/O, such as the Due, Zero, etc. can be used directly with the ARD-LTC1867.

The Arduino Mini, Micro, and Nano, do not provide the standard Arduino header connectors and thus cannot be directly used with the ARD-LTC1867.
