TPMC554 16/32 Channel 16 Bit DA Converter with SRAM

32 16 bit analogue output channels. A 16 channel version is also available. The output voltage range is 0-5V, 0-10V, 0-10.8V, +/-5V, +/-10V or +/-10.8V and can be individually set per channel. The conversion time is typ. 10 µs and the DAC outputs are capable to drive a load of 2 KΩ, with a capacitance up to 4000 pF. A sequencer allows periodic updates of enabled channels with a sequence time range that extends from 10 µs to 11.93 h.

In addition to the double buffered distributed RAM inside the FPGA the TPMC554 provides 2 M x 16bit external SRAM to store values that are known in advance. This feature can also be used to periodically output any kind of waveform or bit pattern. The size of the FIFO for each DAC channel is adjustable.

The DA converter are available with front panel IO. The TPMC554 PMC module is factory calibrated. The calibration data is stored in the Identification-PROM.

A wide range of drivers is available: Linux, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.
