Operational Amplifier drives wide variety of loads
Operating from single or dual supplies, Model OPA567 has rail-to-rail swing on input and output. Output swing is within 300 mV of supply rails with output current of 2 A. Diagnostic flag is provided for temperature overstress and can be configured to provide thermal shutdown. Housed in 5 x 5 mm QFN package, op amp is suited for driving valves, actuators, laser diode pumps, and servo motors, as well as thermoelectric coolers and synchro drivers.
Dallas, TX - Texas Instruments Incorporated (NYSE: TXN) introduced a high-current, low-cost power operational amplifier (op amp) designed for driving a wide variety of loads while operating on low- voltage supplies. The easy-to-use OPA567, from the company's Burr-Brown product line, operates from either single or dual supplies for design flexibility and can be used in virtually any op amp configuration.
This unity gain stable device has rail-to-rail swing on the input and output. The output swing is within 300mV of the supply rails with output current of 2A. Lower-current loads allow an output swing closer to the rails resulting in higher performance. The op amp is ideal for driving valves, actuators, laser diode pumps and servo motors. Other applications include thermoelectric coolers, synchro drivers and transducer excitation. The OPA567 can be integrated with a 12-bit A/D and D/A component such as the AMC7823 or a standalone 12-bit D/A converter such as the DAC7551. An additional feature of the OPA567 is a diagnostic flag for temperature overstress. The temperature flag can also be configured to provide thermal shutdown.
Digital Recorders feature removable drives
Suited for acquisition of sensitive data in secure establishments, Series GSR provides all-digital recording, flexible signal interfacing, and removable media. Rack-mounted, 256 Mbit/s units are capable of simultaneously acquiring multiple streams of data from ground, airborne, and satellite telemetry sources. Data retrieval may be via real-time reconstruction of original signal sources or by direct high-speed transfer of digital data to user's computing platform.
Ideal for Acquisition of Sensitive Data in Secure Establishments
Heim Data Systems, Inc., a leading supplier of data acquisition equipment, introduces the new GSR Series with removable drives for high security missions involving the acquisition of sensitive data. Ideal for ground-based telemetry, satellite down link, multi-channel analog and bus recording, the easy- to- use GSR Series features all digital recording, high data integrity, flexible signal interfacing and removable media. Common applications for the GSR include recording satellite down link data and range telemetry.
The GSR Series is an economical, rack-mounting, 256 Mbit/s digital recorder capable of simultaneously acquiring multiple streams of data from ground, airborne and satellite telemetry sources. Once the data is acquired, it is recorded to a storage media system for later retrieval and analysis. Data retrieval may be via real time reconstruction of the original signal sources or by direct high-speed transfer of digital data to the user's computing platform over popular buses.
Heim's new GSR Series deploys the record media in an easily removable plug-in carrier. The carrier mates with a commercially available receiver in the GSR which allows physical removal of sensitive data at the completion of a secure mission, leaving the GSR free of non-volatile signal data memory. In addition to safe storage, the removable drives also allow multiple secure and non-secure missions to be run on the same GSR by dedicating separate record media carriers to each mission. The installation of compatible drive receivers in the user's analysis computer also provides a simple and secure means of rapid upload or download of large volumes of mission data to and from the GSR by the physical transfer of drive carriers.
