DATEL Inc. (Mansfield, MA) announced two new additions to its family of miniature electronic loads. Designed for use in the cost-effective implementation of computer-controlled, power-supply and power-component test and burn-in, the DTL3A and DTL4A are digitally controlled, near ideal, current sources.
The DTL3A features an output/load current of 0A to 2A, over an operating voltage range of 2.5V to 200V, giving it a resolution of 500µA per LSB. The DTL4A features an output/load current of 0A to 10A, over an operating voltage range of 2.5V to 150V, giving it a resolution of 2.5mA per LSB. Both are rated to a maximum output/load power of 100W.
The DTL3A and DTL4A exploit 12-bit digital-to-analog converters to achieve their high-resolution current control. The D/A output drives a near-ideal, voltage-controlled current source. In the case of the DTL3A, the output current source can tolerate load voltages up to 200V. For the DTL4A, the load voltage can be as high as 150V.
The DTL3A and DTL4A both guarantee ±0.1 percent maximum gain error, ±0.5/3mA maximum offset error, and ±1 percent overall accuracy. Additionally, all DTLs feature miniature 2in x 2in x 0.5in, six-side shielded, metal packages that are heat-sink friendly.
The DTL3A and DTL4A are priced at $249 each in singles and $112 each for 1,000 pieces. Additional high-quantity discounts are available for OEM customers. Small quantities and consignment evaluation units for qualified OEMs are immediately available from stock. Production quantities require six to eight weeks.
