MCC USB-1408FS-Plus
The USB-1408FS-Plus is the 14-bit sibling of the USB-1208FS-Plus, with the same 8 single-ended or 4 differential inputs, two 12-bit analog outputs, 16 digital lines and a 32-bit counter. It resolves 14 bits differentially at up to 48 kS/s, for users who want finer steps than 12 bits without buying a 16-bit device.

USB-1408FS-Plus vs USB-1208FS-Plus
The two devices share a datasheet, a pinout and an enclosure. The USB-1408FS-Plus resolves 14 bits in differential mode and 13 bits single-ended and tops out at 48 kS/s aggregate, where the USB-1208FS-Plus gives 12 and 11 bits at 50 kS/s. On the ±10 V differential range, 14 bits works out to about 1.2 mV per code, against about 4.9 mV at 12 bits. The ADC resolution calculator runs those numbers for the other ranges. Code size and accuracy are separate specifications, so check the datasheet’s accuracy table before you rely on the extra bits.
Differential ranges run from ±20 V to ±1 V in eight steps, and single-ended inputs are fixed at ±10 V. Both analog outputs are 12-bit, 0 to 5 V. There are 16 digital lines on two 8-bit ports and one 32-bit counter rated to 1 MHz. List price at the time of writing is about $297 at Mouser.
Software on each operating system
On Windows, MCC supports it with InstaCal for setup, the Universal Library for programming and DAQami for logging. On Linux and macOS, the open-source uldaq library supports the USB-1408FS-Plus from C and Python, and MCC has no logging app for either platform. MCC DAQ on Linux and Raspberry Pi walks through a uldaq install. DAQAtlas, which is in development, drives the device through the same library and can record it in one run with a LabJack or a SCPI meter.
Questions
Does the USB-1408FS-Plus work on macOS or Linux?
Yes. MCC’s uldaq library supports the USB-1408FS-Plus on Linux and macOS, with C and Python interfaces. InstaCal and DAQami are Windows only.
Is the USB-1408FS-Plus 14-bit in single-ended mode?
No. It is 14-bit in differential mode and 13-bit in single-ended mode, where the range is fixed at ±10 V.
Should I buy the USB-1208FS-Plus or the USB-1408FS-Plus?
They have the same I/O. Pick the USB-1408FS-Plus if you need finer resolution on differential inputs; the USB-1208FS-Plus is cheaper and slightly faster at 50 kS/s.
