Industry Pack Modules IP236 16-bit D/A Analog Output with FIFO Buffers IP236 modules have 16-bit D/A converters (DAC) to provide highly-accurate analog voltage outputs. FIFO The IP236 is ideal for generating waveforms. Large FIFO buffers reduce CPU interactions for increased overall performance. buffers enhance control over the transfer of data to the DAC and improve efficiency. Environmental Specifications Operating temperature: 0 to 70°C (IP236-4/8) Each channel has a dedicated 128 sample FIFO buffer Analog Outputs or -40 to 85°C (IP236-4E/8E models). and its own clock. A start trigger transfers digital Output configuration: 4 (IP236-4/4E) or 8 (IP236-8/8E). Storage temperature: -55 to 125°C (all models). values from the buffer to the DAC. Three modes offer D/A Resolution: 16 bits. Relative humidity: 5 to 95% non-condensing several choices for the data transfer on each channel. Output ranges: ±5V, ±10V, 0 to 10V Power: Continuous mode cycles data through the buffer for a (jumper-selectable). +5V (±5%): 250mA maximum.. given channel and is ideal for waveform generation. Data sample memory: 128 sample FIFO buffer on ±12V (±5%) from P1: 210mA maximum. As new data loads into the FIFO, the output signal each channel.
