Ordering Guide

The DMM-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.
