OVERVIEW
The TS-ADC16 is a 8-bit (16-bit in ARM mode) PC/104 peripheral board (standard format) that provides 16 channels of 16-bit analog to digital conversion (ADC or A/D converter) with internal 512x16bit RAM-FIFO. In addition, it provides 4 channels of 12-bit digital to analog conversion (DAC), 4 16-bit counters, 4 digital inputs and 1 digital output. It is a strong solution for data acquisition, measurement, control and analog interface applications. Features include:
