Data Translation DT5712-PGH Q-Bus DataxII Data Acquisition Module 12-Bit 16SE

Data Translation DT5712-PGH Q-Bus DataxII Data Acquisition Module 12-Bit 16SE

The Data Translation DT5712-PGH is a DataxII-series analog input data acquisition module designed for DEC Q-Bus systems. It provides 12-bit A/D conversion with a wide input voltage range — from low-level signals as small as 10mV up to ±10V full-scale — making it suitable for a broad range of sensor and instrumentation signal types. The board features an integrated instrumentation amplifier, programmable gain, sample-and-hold, and A/D converter as shown in the silk-screened block diagram on the card face.

Applications

The DataxII series of Q-Bus data acquisition cards was designed for use in DEC Q-Bus-based minicomputer and workstation systems, including PDP-11 series, MicroVAX, VAXstation, and related platforms. These cards were used in laboratory automation, industrial process monitoring, scientific data collection, and instrumentation applications where analog signals from sensors, transducers, or test equipment needed to be digitized and processed by the host system. The wide input range — spanning low-level millivolt signals through full ±10V — made cards like the DT5712-PGH particularly flexible for mixed-signal environments. Data Translation was a leading supplier of data acquisition hardware for DEC systems throughout the 1980s and into the 1990s, and their DataxII product line served a wide range of OEM and research customers. Today these cards are sought by engineers maintaining legacy Q-Bus systems, as well as collectors of DEC-era computing hardware.
