The various ranges specified are as follows:. This is also referred to as relative accuracy. These pins are used for internal filtering. 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.

Serial Input 16-Bit, 4-20 MA, 0-20 MA DAC

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. The DAC output will not update if a “framing error” datasjeet detected.

This can be one daatasheet 4 stages: 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. World Wide Web Site: The AD is a complete digital to current loop output.

On-Chip loop fault detection. Similarly, the clock line should remain low during updates of the DAC via the latch pin. Temperature Range This is the acceptable operating range of the device.

SPI is a registered trademark of Motorola. 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. One Technology Way, P.

Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Digital Inputs to GND. It provides a high precision, fully integrated, low cost single-chip solution for generating current loop signals in a compact lead Da420 package. The single bit stream from. The output current range can be programmed to 4 mA to. Since the comparison is made within the feedback loop of the output amplifier, the output accuracy is maintained by its open-loop gain, and no output error occurs before the fault detect output becomes active.

The voltage compliance is the maximum voltage at the I.

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. If a model is not available for web samples, look for notes on the product page that indicate how to request samples or Contact ADI.

We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. Specifications subject to change without notice. The filtered current is. Part Name Included start with end match. The output current range can be programmed to 4 mA to 20 mA, 0 mA to 20 mA or to an overrange function of 0 mA to 24 mA.

It provides a high precision, fully integrated, low cost single-chip solution for generating current loop signals in aad420 compact lead SOIC or PDIP package. The AD can alternatively provide a voltage output. In the three-wire interface mode, this output can be used for daisy-chaining multiple ADs. If a user wants to. Timing Specifications for Asynchronous Interface. The AD uses sigma-delta. Full-scale settling ad402 0. The AD is a single chip solution for generating 4 mA to.
