DAC with Dynamic Power Control Optimizes Thermal

nnnn

Management in Multichannel Industrial Control Applications

nnnn

As the density of factory process control terminals increases, the system power dissipation reaches

nnnn

levels where thermal issues begin to undermine equipment performance, reliability, and safety.

nnnn

Solution o-

nnnn

The AD5755 is a complete, multichannel control IC that incorporates on-chip dynamic power

nnnn

control with four precision 16-bit programmable voltage, or 4 mA to 20 mA current, output DACs.

nnnn

The dynamic power control works by continually sensing the load impedance and delivering the

nnnn

required power to the load while minimizing power loss in the rest of the system. This reduces

nnnn

self-heating and temperature elevation in dense, multichannel systems by 75% and lowers overall

nnnn

power consumption by 80% compared to other control technologies. The AD5755 offers fully

nnnn

specified performance with maximum total unadjusted error of 0.05% and a relative accuracy of

nnnn

±0.006% max—meaning system calibration is no longer required. Supporting standard industrial

nnnn

voltage and current output ranges, the AD5755 can be used with standard HART protocol modems.
