Product details
Overview
AD1583ARTZ-REEL7 from Analog Devices is a 3.0 V, micropower series voltage reference IC with ±3 mV initial accuracy (B-grade), 50 ppm/°C max temperature coefficient, and 70 µA max quiescent current - designed for precision analog signal chains in battery-powered instrumentation and automotive sensor modules.
For engineers reviewing the AD1583ARTZ-REEL7 datasheet, AD1583ARTZ-REEL7 pinout, AD1583ARTZ-REEL7 application, or AD1583ARTZ-REEL7 equivalent, key selection criteria include supply headroom (200 mV min), load regulation (0.45 mV/mA over −40°C to +125°C), noise (60 µV rms, 10 Hz–10 kHz), and SOT-23-3 automotive qualification.
Technical Context
The AD1583ARTZ-REEL7 implements a band gap-based series reference architecture with patented temperature drift curvature correction, enabling stable 3.0 V output across −40°C to +125°C without external trimming. It sources or sinks up to ±5 mA while maintaining regulation with only 200 mV of VIN–VOUT headroom.
Its dynamic performance includes 80 dB ripple rejection at 120 Hz, 120 µs turn-on settling time to 0.1% with 0.2 µF load capacitance, and low-noise operation supported by internal compensation - eliminating need for external feedback components in most precision ADC/DAC biasing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000 V ±3 mV at 25°C - guarantees 12-bit converter reference accuracy without calibration. |
| Temp Coefficient | 50 ppm/°C max (−40°C to +125°C) - limits full-range drift to ±8 mV, enabling high-stability sensor front-ends. |
| Quiescent Current | 70 µA max - enables multi-year operation on coin-cell batteries in portable DMMs and IoT sensors. |
| Supply Headroom | 200 mV min (VIN ≥ VOUT + 200 mV) - supports direct regulation from 3.3 V or 3.6 V Li-ion systems. |
| Noise (10 Hz–10 kHz) | 60 µV rms - contributes <0.02% error to 16-bit SAR ADCs with 3 V full-scale range. |
| Load Regulation | 0.45 mV/mA (−40°C to +125°C) - ensures stable reference under varying DAC or op-amp bias loads. |
| Long-Term Stability | 100 ppm/1000 hr - maintains calibration integrity in industrial transmitters over 5+ year deployments. |
Pinout & Package
AD1583ARTZ-REEL7 is housed in a compact, surface-mount SOT-23-3 (RT suffix) package, qualified for automotive applications and rated for −40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT | Reference Output | Stable 3.0 V source/sink node; requires 1 µF ceramic capacitor for stability under full ±5 mA load. |
| GND | Analog Ground | Low-impedance return path for reference current and load current; must connect directly to clean system ground plane. |
| VIN | Input Supply | Unregulated input accepting 3.2 V to 12 V; minimum 200 mV headroom above VOUT required for regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Series topology | Eliminates wasteful series resistor - achieves full efficiency across input voltage range without power loss scaling. |
| Automotive qualification | Meets AEC-Q100 stress test requirements for engine control, ADAS sensors, and infotainment power rails. |
| Low dropout headroom | 200 mV allows direct use after LDOs or buck converters with minimal voltage margin overhead. |
| Wide temperature range | Specified performance from −40°C to +125°C enables deployment in under-hood and industrial environments. |
| Low wideband noise | 60 µV rms (10 Hz–10 kHz) minimizes quantization uncertainty in high-resolution data acquisition systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3030AIDBZR | 3.0 V, 50 ppm/°C, 50 µA IQ, SOT-23-3 - lower quiescent current but no automotive qualification. | Preferred for non-automotive portable devices where ultra-low IQ dominates over environmental ruggedness. | Select REF3030AIDBZR when supply current is below 50 µA target and AEC-Q100 is not required. |
| ADR3430ARJZ-R7 | 3.0 V, 10 ppm/°C max, 120 µA IQ, SOT-23-5 - higher accuracy and noise immunity, but larger footprint and higher power. | Suitable for metrology-grade instruments needing sub-ppm stability, not space-constrained automotive modules. | Choose ADR3430ARJZ-R7 only when TCVO ≤10 ppm/°C is mandatory and SOT-23-5 layout is acceptable. |
Compared with REF3030AIDBZR and ADR3430ARJZ-R7, AD1583ARTZ-REEL7 uniquely balances automotive qualification, 70 µA IQ, and 50 ppm/°C drift in SOT-23-3 - making it optimal for cost-sensitive, space-constrained, and thermally demanding embedded systems where moderate accuracy suffices.

FAQ
What is the output voltage tolerance of AD1583ARTZ-REEL7 at 25°C?
The AD1583ARTZ-REEL7 has an initial output voltage tolerance of ±3 mV (±0.1%) at 25°C, corresponding to the B-grade specification per the AD1583 datasheet Rev. M. This is confirmed in Table 3 under AD1583B parameters, where VO is specified as 2.997 V to 3.003 V at 25°C. The part number suffix "ARTZ" denotes the SOT-23-3 package and B-grade accuracy. AD1583ARTZ-REEL7 maintains this tolerance across its full operating temperature range when combined with its 50 ppm/°C temperature coefficient.
Does AD1583ARTZ-REEL7 support sinking current, and what is its maximum capability?
Yes, AD1583ARTZ-REEL7 is a true series reference capable of both sourcing and sinking up to ±5 mA of load current, as explicitly stated in the General Description and verified in the Load Regulation specifications (Table 3). It maintains regulation under sink conditions down to −5 mA, with load regulation of 0.6 mV/mA over −40°C to +125°C. This bidirectional capability enables use in active filter biasing, op-amp reference buffering, and DAC output clamping circuits - all within the same AD1583ARTZ-REEL7 device.
What decoupling capacitors are required for stable operation of AD1583ARTZ-REEL7?
Per the Applications Information section (Page 12), AD1583ARTZ-REEL7 requires a 4.7 µF input capacitor and a 1 µF output capacitor for stable operation under all loading conditions. For best transient response, a 0.1 µF ceramic capacitor should be placed in parallel with the 4.7 µF input capacitor. Under light-load conditions (−100 µA < IOUT < +100 µA), the output capacitor may be reduced to 0.2 µF. These values are validated in Figure 10 and ensure specified noise, regulation, and settling performance for AD1583ARTZ-REEL7.
Is AD1583ARTZ-REEL7 qualified for automotive applications, and what does that entail?
Yes, AD1583ARTZ-REEL7 is explicitly qualified for automotive applications, as confirmed in the Features and Automotive Applications sections (Page 1 and Page 17). This qualification includes AEC-Q100 stress testing, operation across −40°C to +125°C, and validation for use in engine control units, ADAS sensors, and infotainment systems. The "RT" suffix in the ordering guide denotes automotive-grade packaging and screening, and the device meets requirements for solder heat resistance, thermal hysteresis, and long-term stability under automotive environmental stresses - all documented for AD1583ARTZ-REEL7.
How does the noise performance of AD1583ARTZ-REEL7 compare across frequency bands?
AD1583ARTZ-REEL7 exhibits 85 µV p-p (0.1 Hz to 10 Hz) and 60 µV rms (10 Hz to 10 kHz) noise, as specified in Table 3. This dual-band characterization reflects typical low-frequency flicker noise and mid-band thermal noise contributions. The 60 µV rms value directly impacts 12–16 bit data converters, contributing less than 0.02% of full-scale error for a 3 V reference. Noise spectral density plots (Figure 8) confirm flat response above 10 Hz, validating the 60 µV rms figure for bandwidth-limited precision applications using AD1583ARTZ-REEL7.
