nnnnDAC with Dynamic Power Control Optimizes Thermal
nnnnManagement in Multichannel Industrial Control Applications
nnnnAs the density of factory process control terminals increases, the system power dissipation reaches
nnnnlevels where thermal issues begin to undermine equipment performance, reliability, and safety.
nnnnSolution o-
nnnnThe AD5755 is a complete, multichannel control IC that incorporates on-chip dynamic power
nnnncontrol with four precision 16-bit programmable voltage, or 4 mA to 20 mA current, output DACs.
nnnnThe dynamic power control works by continually sensing the load impedance and delivering the
nnnnrequired power to the load while minimizing power loss in the rest of the system. This reduces
nnnnself-heating and temperature elevation in dense, multichannel systems by 75% and lowers overall
nnnnpower consumption by 80% compared to other control technologies. The AD5755 offers fully
nnnnspecified 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
nnnnvoltage and current output ranges, the AD5755 can be used with standard HART protocol modems.
