TPMC542

TPMC542 16/8 Channel Voltage and Current Range D/A and 20 Channel LVTTL/TTL Digital I/O

16 or 8 channels of simultaneous update single-ended unipolar/bipolar 16 bit analog output and 20 channels of tristate capable 5V tolerant LVTTL/TTL digital input/output. All signals are accessible via Mini-D Ribbon (MDR68) type front I/O connector. The TEWS TPMC542 PMC module provides a D/A sequencer unit for periodic simultaneous digital to analog conversions at a configurable conversion rate.

The DAC offers software selectable 0-5V, 0-10V, +/-5V, +/-10V, 0-6V, 0-12V, +/-6V and +/-12V output voltage ranges (one setting for all channels). The digital I/O lines are ESD protected. Each digital I/O line has a dedicated line transmitter with individual output enable control and a dedicated line receiver. The receivers are always enabled so the digital I/O line level can always be monitored. Each digital I/O line input is capable of generating an interrupt triggered on rising edge, falling edge or both.

Each TPMC542 is factory calibrated. The correction data is stored in an onboard serial EEPROM. These correction values may be used to perform a hardware correction for every D/A channel and output range.

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