AD420ZRZ-32

The AD420ZRZ-32 is designed as 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.

AD420ZRZ-32 has twelve features. (1)4mA to 20mA, 0mA to 20mA or 0mA to 24mA 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 (3.3MBPS). (7)On-chip loop fault detection. (8)On-chip 5V reference (25ppm/°C max). (9)Asynchronous CLEAR function. (10)Maximum power supply range of 32V. (11)Output loop compliance of 0V to Vcc-2.5V. (12)24-lead SOIC and PDIP packages. Those are all the main features.

Some absolute maximum ratings of AD420ZRZ-32 have been concluded into several points as follow. (1)Its Vcc to GND would be 32V. (2)Its Iout to GND would be Vcc. (3)Its digital inputs to GND would be from -0.5V to 7V. (4)Its digital output to GND would be from -0.5V to Vll+0.3V. (5)Its Vll and REF out would mean outputs safe for indefinite short to ground. (6)Its storage temperature range would be from -65°C to 150°C. (7)Its lead temperature soldering 10 seconds would be 300°C. (8)Its thermal impedance would be 75°C/W. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of AD420ZRZ-32 are concluded as follow. (1)Its resolution would be min 16bits. (2)Its operating current ranges would be min 4mA and max 20mA. (3)Its current loop voltage compliance would be min 0V and max Vcc-2.5V. (4)Its settling time (to 0.1% of FS) would be typ 2.5ms and max 3ms. And so on.
