Overview
The ADR1581ARTZ-R2 is a precision shunt voltage reference manufactured by Analog Devices Inc. It provides a stable 1.25 V output with an initial accuracy of ±0.12% maximum and a temperature drift of ±50 ppm/°C maximum. The device operates within a wide current range from 60 μA to 10 mA and features a dynamic output impedance of 0.5 Ω maximum. It exhibits low broadband noise of 20 μV rms (10 Hz to 10 kHz) and functions reliably across an operating temperature range of −40°C to +85°C.
Feature Summary
- Precision band gap design utilizing proprietary curvature correction for minimized nonlinearities
- Stable operation with any value of capacitive load without oscillation
- High electrostatic discharge protection rating of 4 kV human body model
Applications
- Portable, battery-powered equipment
- Cellular phones, notebook computers, PDAs, GPSs, and DMMs
- 3 V/5 V, 8-bit to 12-bit data converters
Procurement Notes
Verify the specific suffix R2 indicates cut tape packaging rather than reel quantities when sourcing. Confirm RoHS compliance status through official documentation as manufacturing processes may evolve. Ensure the ordering code matches the required initial accuracy grade and temperature coefficient specifications for the target application environment.
Selection Notes
Select this component for applications requiring a compact surface-mount solution with high accuracy in space-critical designs. The micropower consumption makes it suitable for battery-operated systems. Consider the 1.25 V fixed output level and shunt topology requirements before implementation in voltage regulation circuits.
Part Context
This part belongs to the ADR1581 series of micropower precision shunt references. It is available in two grades, A and B, both housed in the SOT-23 package. The ARTZ variant denotes the specific accuracy and temperature coefficient specifications compliant with RoHS standards.
Replacement Considerations
ADR1581BRTZ-R2 offers higher accuracy (±0.01%) and lower drift (±50 ppm/°C). ADR1581ARTZ-REEL7 provides identical electrical characteristics but in reel packaging.
