Performance Specifi cations and Ordering Guide PART NUMBER STRUCTURE MECHANICAL SPECIFICATIONS Input Output DTL 22 DATEL Electronic Load Voltage Range: 22 = 2.5 to 50V A A-Series High Reliability TEMPERATURE DERATING I/O Connections Contact DATEL for Heat Sink information. The horizontal axis of the above chart references the temperature of the DTL22A’s aluminum baseplate. The device can continually dissipate up to 100 Watts if the baseplate is maintained at or below +50°C. At +25°C ambient temperature, with no heat sink or supplemental air fl ow, the DTL22A can reliably dissipate a continuous 10 Watts.

One LSB (least signifi cant bit) of the D/A corresponds to 0.0244% (1/4096) of full scale (20 Amps), which equals approximately 5mA. ➂ For proper operation, the unit's output/load voltage must remain within this range. Voltages greater than the listed maximum can damage the device. Voltages less than the minimum provide insuffi cient bias for the output stage and will result in unpredictable or no operation.

One LSB (least signifi cant bit) of the D/A corresponds to 0.0244% (1/4096) of full scale (20 Amps), which equals approximately 5mA. ➁ Offset error is defi ned as the current sunk/sourced by the DTL22A’s output, under any output-voltage conditions, when the applied control voltage is 0 Volts. ➂ Applies over all ranges/combinations of specifi ed output current, load voltage, output power, operating temperature and V CC. ➃ For proper operation, the DTL22A's output voltage must remain within the range listed. Voltages greater than the listed maximum can damage the device. Voltages less than the listed minimum provide insuffi cient bias for the output stage and will result in unpredictable or no operation. See Ouput Compliance Voltage and the Fault Line for details. ➄ The DTL22A can achieve its maximum output/load power only when its baseplate temperature is properly maintained. See Temperature Derating. ➅ Specifi ed for the full-scale step from 10mA to 20 Amps settling to ±1% (±200mA) of fi nal value.

Exposure of devices to any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than those listed in the Performance/Functional Specifi cations Table is not implied. TECHNICAL NOTES Overview The DTL22A is an analog programmable (0 to +10V control) current sink. It’s output/load current range is 0 to 20 Amps over a compliance voltage range of 2.5 to 50 Volts and an output/load power range of 0 to 100 Watts. The device’s transfer function is as follows: Iout (Amps) = 2V IN (Volts) Examples: Control VIN = 1 Volt, IOUT = 2 Amps Control V IN = 10 Volts, IOUT = 20 Amps In a typical power-supply test or burn-in application, the "positive" output and "return" pins of the device under test (DUT) are connected to the DTL22A’s +Load (pins 10 and 11) and –Load (pins 8 and 9) outputs. Performance/Functional Specifi cations Typical @ TA = +25°C with nominal +5V supply voltage, unless noted.
