KPCMCIA-8AO 8-Channel, 12-Bit Bipolar or
Series Unipolar Analog Output Boards
The KPCMCIA-8AOU and -8AOB are 12-bit, 8-channel analog output PCMCIA
cards for use with notebook and other PCs equipped with a PCMCIA port.
These cards are capable of updating multiple outputs simultaneously under
software control or with an external event.
Programmable output voltage for control applications
These cards are designed to support control applications that require a pro-
grammable output voltage, such as dynamic calibration, driving x-y tables,
driving strip chart recorders, controlling pressure valves, etc.
Both cards feature two 4-channel D/A converters (quad DACs) and 12-bit reso-
lution, and they can deliver up to 1mA per channel of output current. The
cards offer eight TTL-compatible digital I/O channels.
The cards provide external interrupt inputs to the PC's CPU. They also pro-
vide an onboard event timer to interrupt the CPU at software programmable
time intervals, allowing the cards to be used as arbitrary waveform synthesiz-
ers. The interrupt latency under Windows could limit the waveform update
rate. The maximum update rate allowed by the hardware is 100kHz. Use of
multiple channels will reduce the maximum rate.
The KPCMCIA-8AOB provides eight
