Description

The AD420ARZ-32 is one member of the AD420 series.The AD420 is a complete digital to current loop output converter, designed to meet the needs of the industrial control market. It provides a high precision, fully integrated, low cost single-chip solution for generating current loop signals in a compact 24-lead SOIC or PDIP package.The 3.3M Baud serial input logic design minimizes the cost of galvanic isolation and allows for simple connection to commonly used microprocessors. 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.

Features of the AD420ARZ-32 are:(1)4 mA20 mA, 0 mA20 mA or 0 mA24 mA current output; (2)16-bit resolution and monotonicity; (3)±0.012% max integral nonlinearity; (4)±0.05% Max offset (trimmable); (5)±0.15% max total output error (trimmable); (6)flexible serial digital interface (3.3 MBPS); (7)on-chip loop fault detection; (8)on-chip 5 V reference (25 ppm/ Max); (9)Asynchronous CLEAR Function; (10)Maximum Power Supply Range of 32 V; (11)output loop compliance of 0 V to VCC 2.5 V; (12)24-lead SOIC and PDIP packages.

The absolute maximum ratings of the AD420ARZ-32 can be summarized as:(1)Vcc to GND:32V;(2)lead temperature (soldering, 10 sec):300;(3)storage temperature:-65 to 150;(4)digital inputs to GND:-0.5 to 7V.Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device.  This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied.  Exposure to absolute maximum rating conditions for extended periods may affect device reliability.ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection.Although the AD420 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
