➀ Typical at TA = +25°C with nominal +5V supply voltage unless noted.
➁ The smallest increment/decrement in output current is defined by one LSB (least significant bit) of the 12-bit
digital input word. One LSB is equal to full scale (FS) divided by 4096 which corresponds to 0.0244% of 20A or 4.88mA.
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.
➃ See Performance/Functional Specifications for details.

Baseplate Temperature (°C)
The horizontal axis of the above chart references the temperature of the DTL2A-LC’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 DTL2A can reliably dissipate a continuous 10 Watts.
