Application Information

The TPMC530 is a standard single width 32 bit PMC with

faceplate I/O. The TPMC530-10R provides 16 channels of

isolated 16 bit simultaneous sampling analog input and 8

channels of isolated 16 bit simultaneous update analog

output. The TPMC530-20R provides 8 ADC channels and

4 DAC channels. All signals are accessible through a

HD50 SCSI-2 type front I/O connector.

The ADC offers true differential inputs with software

selectable ±5 V and ±10 V bipolar input voltage ranges

(one setting for all channels). The sampling rate is up to

200 kSPS and the ADC offers an oversampling capability

with digital filter.

The DAC offers software selectable 0-5 V, 0-10 V, ±5 V

and ±10 V output voltage ranges (one setting for all

channels). 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.

Both ADC and DAC offer programmable sample clocks.

External synchronization is possible with a Trigger/Sync

RS485 I/O.

Each ADC / DAC provides a 1024 sample input / output

FIFO with programmable trigger levels. Data transfer on

the PCI bus is handled by TPMC530 initiated scattergather

DMA cycles with minimum host/CPU intervention.

Each TPMC530 is factory calibrated. The calibration can

be automatically applied to data written to and read from

the TPMC530.

Software Support (TDRV021-SW-xx) is available for

different operating systems.
