High-bandwidth SMD op-amps

Intersil has introduced 10 high-bandwidth SMD op-amps certified to operate over the full military temperature range. For design versatility, two families of products are available. The first family includes three parts featuring fixed-gain amplifiers. The 5962-0625501QHC delivers 350 MHz bandwidth, while the 5962-0625601QHC and 5962-0625602QHC feature up to 1.4 GHz of bandwidth. The wide bandwidths make the products ideal for general-purpose applications with the potential to be used in several high-reliability applications, such as software-defined radios. The 5962-0625501QHC integrates the gain and series resistor to reduce gain error and save board space.

The second family is comprised of seven parts with variable gain amplifiers. The 5962-0623501QPC, 5962-0623502QPC, 5962-0623601QPC, 5962-0623602QPC, 5962-0721301QHC, 5962-0721302QHC and 5962-0721303QDC include dual and quad versions that save board space and reduce the amount of decoupling caps required as the op-amps share supply pins. These parts feature bandwidth ranges from 500 MHz to 670 MHz. The 5962-0625501QHC and 5962-0625601QHC are available in 10-lead flat pack configurations, starting at $31.42. The 5962-0625602QHC is available in a 10-lead flat pack, starting at $31.87, all prices for quantities of 100 to 1000.

Thermoelectric cooling film

Nextreme has enhanced its miniature embedded thermoelectric component (eTEC) material to consistently achieve differentials of 55 °C to 60 °C at room temperature. This achievement compares favorably with the performance of conventional thermoelectric technology, which is larger and typically produces 65 °C under the same conditions. The devices are 5 m to 15 m thick, about 100 times thinner than the 1 mm thick pellets used in conventional thermoelectric devices. The eTEC's millisecond response time rapidly cools or heats to maintain a precise temperature depending on the needs of the application. A typical device pumps a maximum heat flux of 150 W/cm², with some designs delivering as much as 400 W/cm² vs. 10 W/cm² to 20 W/cm² for typical bulk TECs. Prototypes for Nextreme's eTEC are available for sampling and are expected to be fully qualified by the third quarter.

The InGaAs SWIR KTSX delivers clear video at every lighting level from partial starlight to direct sunlight due to the on-board automatic gain control, image enhancements, and built-in non-uniformity corrections. The module is less than 4 in.³; it is also available in an enclosed module (less than 9.5 in.³).

Both camera versions operate at room temperature and offer simultaneous 12-bit camera link digital output for high-quality image processing or EIA-170 compatible analog video. SUI's new night/day SWIR imagers are suitable for integration into many low-light-level OEM applications such as rifle sights, field goggles, handheld systems, unmanned ground and air vehicles, and covert surveillance systems with passive 24/7 operation. Other tasks for the camera include emission microscopy, imaging spectroscopy, and astronomy.
