Overview
The DTL3A is a digitally programmable, CMOS/TTL-compatible, serial-input
current sink. It’s output/load current range is 0 to 2 Amps (in 488µA
increments), 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 digital I/O coding is straight
binary (see table below). A digital input of all "0’s" forces a load current of 0
Amps. A digital input of all "1’s" forces a load current of 1.9995 Amps.
In a typical power-supply test or burn-in application, the output pins of the
device under test (DUT) are connected to the DTL3A’s +Load (pins 10 and 11)
and –Load (pins 8 and 9) outputs. The DTL3A’s operation is controlled by its
four digital input lines (Serial Data In, Clock, Latch Data and Control Strobe).
T E C H N I C A L N O T E S
The smallest increment/decrement in output current is defi ned by one LSB (least signifi cant
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 2A or 488µA.
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.
See Output Compliance Voltage and the Fault Line for details.
Offset error is defi ned as the current sunk/sourced by the DTL3A’s output, under any output
voltage conditions, when the digital input word is all "0's."
Full scale step (2 Amps) settling to within ±0.5mA of its fi nal value.
