These are stress ratings.  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 
Specifications Table is not implied.
Absolute Maximum Ratings
 Listed resolution (0.5mA) is for a typical application in which the DTL23A 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 (2.0 Amps), which 
     equals approximately 0.5mA. 
 Offset error is defined as the current sunk/sourced by the DTL23A's output, under any 
     output-voltage conditions, when the applied control voltage is 0 Volts.
 Applies over all ranges/combinations of specified output current, load voltage, output power, 
     operating temperature and V
CC
. 
 For proper operation, the DTL23A'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 insufficient bias for the output stage and will result in unpredictable or 
     no operation.  See Output Compliance Voltage and Fault Line for details. 
 The DTL23A can achieve its maximum output/load power only when its baseplate                
     temperature is properly maintained.  See Temperature Derating.

TECHNICAL NOTES
Overview
The DTL23A is an analog programmable (0 to +10V control) current sink.  Its 
output/load current range is 0 to 2.0 Amps  over a compliance voltage range of 
2.5 to 200 Volts and an output/load power range of 0 to 100 Watts.  The device's 
transfer function is as follows:
                      Iout (Amps) = 0.2V

OUT

In a typical power-supply test or burn-in application, the output pins of the 
device under test (DUT) are connected to the DTL23A's +Load (pins 10 and 11) 
and -Load (pins 8 and 9) outputs.
