In the AD a second order modulator is used to keep com- plexity and die size to a minimum.

The single bit stream from the modulator controls a switched current source that is then filtered by two, continuous time resistor-capacitor sections. The capacitors are the only external components that have to be added for standard current-out operation.

The filtered current is amplified and mirrored to the supply rail so that the application simply sees a 4 mA—20 mA, 0 mA—20 mA, or 0 mA—24 mA current source output with respect to ground. The AD is manufactured on a BiCMOS process that is well suited to imple- menting low voltage digital logic with high performance and high voltage analog circuitry.

The AD can also provide a voltage output instead of a cur- rent loop output if desired.

The AD has a loop fault detection circuit that warns if the voltage at I OUT attempts to rise above the compliance range, due to an open-loop circuit or insufficient power supply voltage. Instead, the signal is generated when the internal ampli- fier in the output stage of the AD has less than approximately one volt remaining of drive capability when the gate of the output PMOS transistor nearly reaches ground. Since the comparison is made within the feedback loop of the datashdet amplifier, the output accuracy is maintained by its open-loop gain, and no output error occurs before the fault detect output becomes active.
