AD1580ARTZ-REEL7

Overview

The AD1580ARTZ-REEL7 is a precision shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed output of 1.225 V with an initial accuracy of ±0.1% and a maximum temperature drift of 100 ppm/°C. The device operates within a current range of 50 µA to 10 mA and features a dynamic output impedance of 0.4 Ω at 120 Hz. It supports a wide operating temperature range from −40°C to +85°C and includes high ESD protection ratings of 4 kV (Human Body Model) and 400 V (Machine Model).

Feature Summary

Utilizes proprietary curvature correction design techniques to minimize non-linearities in voltage output temperature characteristics.
Maintains stability with any value of capacitive load without requiring external isolation resistors for standard operation.
Features high electrostatic discharge (ESD) susceptibility ratings to protect against human body and machine model events.

Applications

Portable, battery-powered equipment such as cellular phones, notebook computers, PDAs, GPSs, and digital multimeters.
Computer workstations suitable for use with a wide range of video RAMDACs.
Smart industrial transmitters and PCMCIA cards.
Automotive applications.
3 V/5 V, 8-bit to 12-bit data converters.

Procurement Notes

Verify the specific suffix 'REEL7' corresponds to the required tape and reel packaging configuration for automated assembly. Confirm that the 'Z' designation indicates RoHS compliance status as defined by the manufacturer's current standards. Ensure the ordering part number matches the exact grade and package option listed in the official Analog Devices Ordering Guide to avoid functional discrepancies.

Selection Notes

Select this component when a low-cost, two-terminal shunt reference is required for space-constrained designs. The SOT-23 package offers a compact surface-mount solution ideal for portable devices. Consider the 100 ppm/°C temperature coefficient if higher precision grades like the B version are not necessary for the application's error budget.

Part Context

This part belongs to the AD1580 family of micropower precision shunt voltage references. It is functionally similar to the AD1581 and AD1582 but provides a lower 1.225 V output compared to their respective voltages. The ARTZ variant specifically denotes the A-grade accuracy level housed in the SOT-23-3 package with RoHS-compliant manufacturing processes.
