Description

The Diamond-MM-16-AT features top performance and flexibility for a mid-range price. It has 16 single-ended / 8 differential analog inputs with both unipolar and bipolar input ranges and programmable gain. It has a maximum sampling rate of 100KHz, supported by a 512-sample FIFO with a 256-sample threshold for gap-free A/D sampling. Both single-channel and multi-channel scan sampling modes are supported. The A/D can be triggered with a software command, the on-board programmable timer, or an external signal. These feature give you maximum flexibility to configure the board to your application.

Analog Inputs

The 16 16-bit analog input channels on Diamond-MM-16-AT feature programmable gains of 1, 2, 4, and 8, as well as programmable unipolar/bipolar range, for a total of 7 different input ranges. Maximum sampling rate is 100KHz (total for all channels), and a new 512-sample FIFO enables the board to operate at full speed in Windows operating systems using interrupts. DMA is no longer required to attain full speed.

Analog Outputs

The board also has 4 12-bit D/A channels with multiple unipolar and bipolar output ranges. The DACs feature simultaneous update capability. A new programmable output range feature lets you set the output range via software anywhere between 0V and 10V with 1mV precision in both unipolar and bipolar modes.

top
Autocalibration

Both analog inputs and outputs benefit from our unique multi-range autocalibration process. Multiple on-board precision references are used to calibrate the board in each range, thereby ensuring the highest degree of accuracy. The analog outputs are also fed back to the autocalibration circuit for precise output range calibration as well as user-programmable output ranges.

top
Counters and Digital I/O

Diamond-MM-16-AT has an on-board counter/timer to control A/D sampling or rate generator functions, 8 digital inputs, and 8 digital outputs. New features enable you to generate hardware interrupts from the counter/timer as well as an external digital signal. And in keeping with our real-world-friendly design, Diamond-MM-16-AT requires only +5V power supply and operates over the full industrial temperature range of -40 to +85oC.
