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.

Specified for the full-scale step from 10mA to 2.0 Amps settling to ±1% (±20mA) of final
value. A minimal loading of 10mA is recommended to achieve the fastest dynamic response.

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
IN
(Volts)
Examples: Control V
IN
= 1 Volt, I
OUT
= 0.2 Amps
Control V
IN
= 10 Volts, I
OUT
= 2.0 Amps
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.
