8-Channel 12-Bit 200ksps ADC Data Acquisition Shield for Arduino
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. A SPI interface allows fast communication to the ADC. The onboard EEPROM can be used to store calibration and configuration information directly on each ARD-LTC1863 board. A 6-byte EUI-48-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.
- 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-48-compatible globally unique ID
- Arduino form factor and software library
- SPI + I2C Interface
Compatible Arduino Boards
The ARD-LTC1863 uses the programming header for the SPI wires (MISO, MOSI, SCLK), D3 or D8 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-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.
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
The Arduino Mini, Micro, and Nano, do not provide the standard Arduino header connectors and thus cannot be directly used with the ARD-LTC1863.

News & Application Notes
Solar Car Teams
As alumni of the Iowa State University Solar Car Team, Team PrISUm, we recognized that many of Iowa Scaled Engineering’s products could be used by teams competing in solar racing competitions.Â In fact, MRBus had its origins in the Sunrayce ’99 car, PrISUm Phoenix.
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.Â 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.
