Typical Applications (continued)

Figure 15. Paralleled Operation, Extended SOA

8.2.2.1 Design Requirements

Design requirements for the parallel connection in Figure 15 are shown here. The maximum current available

from a single OPA541 cannot exceed 10 A:

•

Gain from input to output of –10

•

Current capability of > 15 A

•

Short to ground on ±15-V supply rails at 25°C case temperature

8.2.3 Programmable Voltage Source

The programmable voltage source of Figure 16 uses the OPA541 as a current-to-voltage converter for a current

output DAC (digital-to-analog converter). The diodes clamp any differential input voltages to safe levels for the

OPA541. The OPA541 provides the gain to produce the desired output.

8.2.3.1 Design Requirements

Design requirements for Figure 16:

•

Convert 0 to –2-mA current input to 0-V to 50-V output voltage

•

Current capability of > 2.5 A

•

Protection of current output DAC during fast slew
