ADR1581BRTZ-REEL7

Overview

The ADR1581BRTZ-REEL7 is a precision shunt voltage reference providing a nominal output of 1.250 V. It operates within an input current range of 60 μA to 10 mA and maintains an initial accuracy of ±1 mV (±0.08%). The device features a maximum temperature drift of 50 ppm/°C over the industrial operating temperature range of −40°C to +85°C. It utilizes a proprietary curvature correction design to minimize nonlinearities in voltage output characteristics. The component is housed in a compact SOT-23 surface-mount package.

Feature Summary

Proprietary curvature correction design minimizes nonlinearities in voltage output temperature characteristics
Stable with any value of capacitive load without oscillation
High electrostatic discharge rating of 4 kV human body model
Low minimum operating current suitable for battery-powered systems

Applications

Portable, battery-powered equipment
Cellular phones, notebook computers, PDAs, GPSs, and DMMs
Smart industrial transmitters
PCMCIA cards
Automotive applications

Procurement Notes

Verify the specific suffix 'REEL7' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status via manufacturer documentation. Ensure the ordering code matches the B grade specifications for ±1 mV accuracy and 50 ppm/°C drift. Check for availability constraints as distribution may vary by region.

Selection Notes

Select this component for applications requiring high precision in a small footprint. The B grade offers tighter accuracy than the A grade. Consider the low minimum operating current for power-sensitive designs. Verify that the required output impedance and noise performance meet system requirements.

Part Context

This part belongs to the ADR1581 family of micropower, precision shunt voltage references from Analog Devices. It serves as a stable voltage source for data acquisition systems. The family includes variants with different accuracy grades and packaging options, all sharing the same core bandgap reference architecture.
