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 flow, the DTL22A can reliably dissipate a continuous 10 Watts.

➀ Typical at TA = +25°C with nominal +5V supply voltage, unless noted.
➁ Listed resolution (5mA) is for a typical application in which the DTL22A is controlled by a voltage
generated by a 12-bit D/A converter with a 0-10V output range. One LSB (least significant 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 insufficient bias for the output stage
and will result in unpredictable or no operation. See Output Compliance Voltage and the Fault Line for details.
