Product details
Overview
AD1584ARTZ-R2 from Analog Devices is a precision 4.096 V series voltage reference IC in SOT-23-3 package, delivering ±0.1% initial accuracy, 50 ppm/°C max temperature coefficient, and 70 µA quiescent current. It operates with only 200 mV supply headroom and supports ±5 mA load current, making it ideal for high-resolution ADC/DAC biasing in battery-powered industrial sensors and portable instrumentation.
For engineers reviewing the AD1584ARTZ-R2 datasheet, AD1584ARTZ-R2 pinout, AD1584ARTZ-R2 application, or AD1584ARTZ-R2 equivalent, key selection criteria include guaranteed 4.096 V output at −40°C to +125°C, low 90 µV rms (10 Hz–10 kHz) noise, and automotive-qualified SOT-23-3 packaging for space-constrained embedded systems.
Technical Context
The AD1584ARTZ-R2 implements a patented band gap architecture with curvature-corrected temperature drift compensation, achieving stable 4.096 V output across full industrial temperature range. Its series topology eliminates external current-setting resistors and enables operation down to VIN = VOUT + 200 mV.
It features dynamic output impedance optimized for low-noise data acquisition, with 80 dB ripple rejection at 120 Hz and 0.52 mV/mA load regulation over −40°C to +125°C. The device draws only 70 µA quiescent current with 1.0 µA/V supply sensitivity, ensuring stable power efficiency across wide input voltage variations.

FAQ
What is the guaranteed output voltage tolerance of AD1584ARTZ-R2 over temperature?
The AD1584ARTZ-R2 guarantees 4.096 V ±0.1% initial accuracy at 25°C and 50 ppm/°C maximum temperature coefficient over −40°C to +125°C. This results in a total output variation of ±4.1 mV (±0.1% + ±0.1%) across the full operating range, verified per Table 4 in Rev. M datasheet.
Can AD1584ARTZ-R2 operate from a 4.2 V lithium-ion battery?
Yes. AD1584ARTZ-R2 requires only 200 mV headroom above its 4.096 V output, so it functions reliably down to VIN = 4.296 V. At end-of-discharge (~3.4 V), operation ceases-consistent with its specified 4.296 V minimum supply requirement.
Does AD1584ARTZ-R2 require external capacitors for stability?
Yes. Per Figure 10 in the datasheet, AD1584ARTZ-R2 requires a 1 µF ceramic capacitor from VOUT to GND and a 4.7 µF capacitor from VIN to GND for full-spec performance across all loads and temperatures. A 0.1 µF parallel capacitor improves transient response.
Is AD1584ARTZ-R2 qualified for automotive applications?
Yes. AD1584ARTZ-R2 carries the RT suffix denoting AEC-Q100 Grade 1 qualification (−40°C to +125°C), with testing including thermal cycling, humidity, and mechanical shock per automotive reliability standards.
How does AD1584ARTZ-R2 compare to shunt references like TL431 in power efficiency?
AD1584ARTZ-R2 draws only 70 µA quiescent current regardless of load, while TL431-based shunt designs waste current through an external resistor. For a 5 V supply, TL431 typically consumes ≥1 mA-over 14× more than AD1584ARTZ-R2-making the latter critical for multi-year battery life.
