It can be used in three-wire or asynchronous mode and a serial-out pin is provided to allow daisy chaining of multiple DACs on the current loop side of the isolation barrier. Other models listed in the table may still be available if they have a status that is not obsolete. The single bit stream from the modulator controls a switched current source that is then filtered by two, continuous time resistor-capacitor sections.

Electrostatic charges as high as V readily accumulate on the human body and test equipment and can discharge without detection. The AD has a loop fault detection circuit that warns if the. It is important to note the scheduled dock date on the order entry screen. It can be used in 3-wire or asynchronous mode and a serial-out pin is provided to allow daisy chaining of multiple DACs on the current loop side of the isolation barrier.

Offset error is the deviation of the output current from its ideal value expressed as a percentage of the full- scale output with all 0s loaded in the DAC. Refer to the description of current output operation.

Please Select a Language. This is the acceptable operating range of the device. Timing Specifications for Asynchronous Interface. If the AD is used at extreme temperatures and supply voltages, an external output transistor can be used to minimize power dissipation on the chip via the BOOST pin.

One Technology Way, P. 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. The AD is a complete digital to current loop output.

Once dataeheet order has dataaheet placed, Analog Devices, Inc. The various ranges specified are as follows: At power-up the AD initializes its output to the low end.

BoxNorwood, MAU. Instead, the signal is generated when the internal ampli. The only external components that are. Product Details The Ad4200 is a complete digital to current loop output converter, designed to datasheef the needs of the industrial control market. The model has not been released to general production, but samples may be available.

In the three-wire interface mode, this output can be used for daisy-chaining multiple ADs. The serial data out pin can be used to daisy chain any number of ADs together in 3-wire mode.

Data Clock High Time. Also, please note the warehouse location for the product ordered.

An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board. The only external components that are datashedt in addition to normal transient protection circuitry are three low cost capacitors which are used in the DAC output zd420. Lead Temperature Soldering, 10 sec.

The package for this IC i. For detailed dataseet and chemical composition please consult our Package Site. A DAC is monotonic if the output either increases or remains constant for increasing digital inputs with the result that the output will always be a single-valued function of the input. The data in the input register is unaffected. The pull-up resistor can be tied to the. It provides a high precision, fully integrated, low cost single-chip solution for generating current loop signals in a compact lead SOIC package.

Drift is the change in a parameter such as gain and offset over a specified temperature range. External capacitor selection must be as described in Figure 5. In the AD a second order modulator is used to keep com- plexity and die size to a minimum.

Description Reviews 0 Description The AD is a complete digital to current loop output converter, designed to meet the needs of the industrial control market. This can be one of 4 stages: The capacitors are the only external components that have to be added for standard current-out operation. Select the purchase button to display inventory availability and online purchase options. SPI is a registered trademark of Motorola.

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.

At least one model within this product family is in production and available for purchase. Information furnished by Analog Devices is believed to be accurate and reliable. It can be used in three-wire or asynchronous mode and a serial-out pin is provided to allow daisy chaining of multiple DACs on the current loop side of the isolation barrier.
