Diamond-MM has all the primary features you expect in a high-performance analog I/O board, at a reduced price.
The analog input circuit uses a 12- bit A/D converter and can be configured for single-ended or differential mode and unipolar or bipolar mode. It also offers 10 different input ranges, so it can work with a wide variety of input signals. The maximum A/D conversion rate is up to 20,000 per second using interrupts or up to 100,000 per second using DMA.

Two optional analog outputs provide 12-bit resolution over a 0-5V or user-adjustable range with 8mA drive current and 4μs settling time. The D/A can also be used as a digital attenuator for an analog signal fed into one of the reference inputs.

The board contains 8 digital inputs and 8 digital outputs. It also has an on-board 82C54 counter/ timer chip to control the A/D sampling rate and provide general purpose counting functions.

Diamond-MM is available in four versions: With or without analog outputs, and in commercial (0-70°C) or industrial (-40 to +85°C) operating temperature range.
