Product details
Overview
ADR530BKSZ-REEL7 from Analog Devices is a high-precision shunt voltage reference delivering 3.0 V output with ±0.2% initial accuracy, 40 ppm/°C temperature coefficient, and 22 μV p-p (0.1 Hz to 10 Hz) output voltage noise. It operates from 50 μA to 15 mA and supports industrial temperature range (−40°C to +85°C), enabling use in battery-powered instrumentation and precision data acquisition systems.
For engineers reviewing the ADR530BKSZ-REEL7 datasheet, ADR530BKSZ-REEL7 pinout, ADR530BKSZ-REEL7 application, or ADR530BKSZ-REEL7 equivalent, key selection criteria include shunt reference bias current requirements, trim terminal usability for system-level calibration, SC70 package footprint constraints, and low-noise performance in high-resolution ADC reference designs.
Technical Context
The ADR530BKSZ-REEL7 implements a bandgap-based shunt architecture with curvature-compensated ΔVBE summation to achieve stable 3.0 V output over temperature. Its trim terminal allows ±0.5% output adjustment without degrading temperature coefficient.
It requires no external capacitor for stability and remains functional across any capacitive load. The device maintains low dynamic output impedance (0.2 Ω) and exhibits only 4 mV output voltage change over −40°C to +85°C at IIN = 0.1–15 mA.

FAQ
What is the output voltage tolerance of ADR530BKSZ-REEL7 at 25°C?
ADR530BKSZ-REEL7 has an output voltage of 3.000 V with ±0.2% initial accuracy, corresponding to ±6 mV tolerance at 25°C. This specification is guaranteed for Grade B devices and applies across the full operating current range of 50 μA to 15 mA.
Does ADR530BKSZ-REEL7 require an external capacitor for stability?
No, ADR530BKSZ-REEL7 does not require an external capacitor for stability. Its internal design ensures robust operation with any capacitive load, simplifying layout and reducing BOM count in space-sensitive applications such as wearable sensors and handheld testers.
How is the TRIM terminal used on ADR530BKSZ-REEL7?
The TRIM terminal on ADR530BKSZ-REEL7 allows ±0.5% adjustment of the output voltage using an external potentiometer (e.g., AD5273). This feature enables correction of system-level errors like PCB trace resistance and op-amp input offset without affecting temperature coefficient or noise performance.
What is the maximum operating current for ADR530BKSZ-REEL7?
The absolute maximum reverse current rating for ADR530BKSZ-REEL7 is 25 mA, but its specified operating current range is 50 μA to 15 mA. Exceeding 15 mA may impact long-term reliability and is not characterized in the datasheet.
Is ADR530BKSZ-REEL7 compatible with LM4040-based PCB layouts?
Yes, ADR530BKSZ-REEL7 is pin-compatible with LM4040 and LM4050 in both SC70 and SOT-23-3 packages. Its identical 3-pin V+/V−/TRIM (vs. LM4040's V+/GND/NC) pinout allows direct substitution when TRIM is left unconnected or grounded via resistor network.
