DTL2A Model

100 Watt, Digitally Programmable

Serial-Input, Electronic Loads

DATEL’s new DTL2A is an optically isolated, digitally programmable, serial-input,

electronic load. It is essentially a digitally controlled current source that can sink

currents from 0 to 20 Amps, at loading voltages from 2.5 to 50 Volts, up to a maximum

power of 100 Watts. The DTL2A is packaged in a thermally efﬁcient, 2" x 2" x 0.5"

metal package that incorporates an aluminum baseplate with through-hole spacers

for easy pcb mounting and/or external heat-sink attachment.

The DTL2A accepts a serialized, 12-bit, CMOS/TTL-compatible, digital input word

easily generated by any standard digital I/O card. The DTL2A buffers and then opti-

cally isolates (500Vdc) the digital input data before storing it in a register and present-

ing it to an on-board, 12-bit, digital-to-analog (D/A) converter. The D/A output drives

a near-ideal (10MΩ minimum output impedance), voltage-controlled current source.

One LSB (least signiﬁcant bit) of the D/A converter corresponds to a 5mA increment

(0.025% of 20A) in load current.

The DTL2A features a max. 5mA offset error and a max. 0.1% gain error. It

has an impressive full-scale step response time of 100µsec and can be operated

dynamically at update rates up to 20kHz. Powered by a single +5V supply, the DTL2A

draws a mere 150mA (maximum).

While operating in the constant-current mode up to 20 Amps (100W max. power),

the output compliance voltage of the DTL2A is 2.5 to 50 Volts. Should the output/load

voltage drop below the 2.5V minimum required for proper biasing, an internal monitoring

circuit activates the DTL2A's output Fault line. See DATEL’s DTL2A-LC for compliance

voltages as low as 0.6V.
