For more information about lead-free parts, please consult our Pb Lead free information page. If the AD is used at extreme temperatures and supply voltages, an external output transistor can be used to ad4420 power dissipation on the chip via the BOOST pin. Comparable Parts Click to see all in Parametric Search.

Connect capacitors between each of these.

The DAC output will not update if a “framing error” is detected. The only external components that are required in addition to normal transient protection circuitry are two low cost capacitors which are used in the DAC out-put filter.

AD datasheet(6/11 Pages) AD | Serial Input Bit 4 mA mA, 0 mA mA DAC

The AD is a complete digital to current loop output con- verter, designed to meet the needs of the industrial control market. No internal connections inside device. Temperature Range This is the acceptable operating range of the device. The addition of a single external. The model has not been released to general production, but samples may be available. 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 is the acceptable operating range of the device. The AD is a complete digital to current loop output. If fast edges are expected on the digital input lines, it is recommended that the latch line remain at Logic 0 during serial loading of the DAC. Other models listed in the table may still be available if they have a status that is not obsolete. It provides a high precision, fully integrated, low cost. It provides a high precision, fully integrated, low cost single-chip solution for generating current loop signals in a compact lead SOIC or PDIP package.

Timing Specifications for Asynchronous Interface. Refer to the description of current output operation. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. 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.

Timing Diagram for Asynchronous Interface. In the AD a second order modulator is used to keep com- plexity and die size to a minimum. These pins are used for internal filtering. Your email address will not be published. Pin Count Pin Count is the number of pins, balls, or pads on the device. Similarly, the clock line should remain low during updates of the DAC via the latch pin.

Electrostatic charges as high as V readily accumulate on the human body and test equipment and can discharge without detection.

Total Output Error Drift. Price Rohs Orders from Analog Devices. Model The model number is a specific version of a generic that can be purchased or sampled.

For detailed drawings and chemical composition please consult our Package Site. At least one model within this product family is in production and available for purchase. The voltage compliance is the maximum voltage at the I. It provides a high precision, fully integrated, low cost single-chip solution for generating current loop signals in a compact pin SOIC or PDIP package.

The AD can also provide a voltage output instead of a cur. Full-scale settling to 0. Didn’t find what you were looking for? This architecture is particularly.

The only external components that are re- quired in addition to normal transient protection circuitry are two low cost capacitors which are used in the DAC output filter. At power-up the AD initializes its output to the low end.

The AD is a single chip solution for generating 4 mA to 20 mA or 0 mA to 20 mA signals at the controller end of the current loop. dafasheet

Timing Specification for Three-Wire Interface. Outputs Safe for Indefinite Short to Ground. If the internal reference is used, the reference errors must be added to the Offset and Total Output Errors. Gain error is a measure of the output error between an ideal DAC and the actual device datashete with all 1s loaded after offset error has been adjusted out.

Darasheet is a registered trademark of Motorola. This is the date Analog Devices, Inc. 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.

Temperature ranges may vary by model. One Technology Way, P. BoxNorwood, MAU. The AD is a single chip solution for generating 4 mA to.

If the AD is going to be 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.
