Product details
Overview
ADR01BKSZ-REEL7 from Analog Devices is a precision 10.0 V band gap voltage reference in a 5-lead SC70 package, featuring ±0.05% initial accuracy (B grade), 9 ppm/°C max temperature coefficient, 10 mA output current, and operation from 12.0 V to 36.0 V supply. It delivers stable reference voltage for high-resolution ADCs and industrial process controllers where space and thermal stability are critical.
For engineers reviewing the ADR01BKSZ-REEL7 datasheet, ADR01BKSZ-REEL7 pinout, ADR01BKSZ-REEL7 application, or ADR01BKSZ-REEL7 equivalent, key selection factors include its SC70 footprint, TEMP pin for on-chip temperature monitoring, TRIM pin for output adjustment, low 20 µVp-p (0.1–10 Hz) noise, and −40°C to +125°C extended industrial temperature range.
Technical Context
The ADR01BKSZ-REEL7 implements a band gap core with internal trimming and a buffered output stage, enabling high DC accuracy and low drift over temperature. Its TEMP pin provides a 550 mV baseline with 1.96 mV/°C sensitivity for system-level temperature compensation without external sensors.
It requires no external capacitor for stability and supports load currents up to 10 mA while maintaining ≤70 ppm/mA load regulation and ≤30 ppm/V line regulation across its full operating range. The device achieves 4 µs turn-on settling time and 50 ppm long-term stability over 1000 hours.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR01AKSZ-REEL7 | Same SC70 package but A grade: ±0.1% initial accuracy, 10 ppm/°C max TC (vs. B grade's ±0.05%, 9 ppm/°C). | Suitable for cost-sensitive designs where 0.05% tighter initial tolerance is not required. | Select ADR01AKSZ-REEL7 if system-level calibration is performed or long-term drift dominates initial error budget. |
| REF01CSZ-REEL7 | 8-lead SOIC package, ±0.1% initial accuracy, 25 ppm/°C max TC, no TEMP pin, requires external capacitor for stability. | Legacy drop-in replacement in existing SOIC footprints; lacks integrated temperature sensing. | Choose REF01CSZ-REEL7 only when reusing legacy SOIC layouts and temperature monitoring is handled externally. |
Compared with ADR01BKSZ-REEL7, the ADR01AKSZ-REEL7 trades 0.05% initial accuracy for lower cost, while the REF01CSZ-REEL7 sacrifices SC70 size, TEMP functionality, and capacitor-free operation to maintain compatibility with older REF01-based designs.

FAQ
What is the maximum input voltage rating for ADR01BKSZ-REEL7?
The ADR01BKSZ-REEL7 has an absolute maximum supply voltage of 36.0 V. Its recommended operating range is 12.0 V to 36.0 V, with dropout voltage remaining ≤2 V across this range and full 10 mA load. Exceeding 36.0 V may cause permanent damage per the Absolute Maximum Ratings table in the Rev. S datasheet.
Does ADR01BKSZ-REEL7 require an external output capacitor?
No, the ADR01BKSZ-REEL7 is internally compensated and does not require an external output capacitor for stability. It remains stable with capacitive loads up to 100 nF, as confirmed in the Applications Information section and Figure 31 of the Rev. S datasheet. Adding one is unnecessary and may degrade transient response.
How is the TEMP pin used in ADR01BKSZ-REEL7?
The TEMP pin on ADR01BKSZ-REEL7 outputs a ratiometric voltage of 550 mV at 25°C with a linear sensitivity of 1.96 mV/°C. It is used for on-die temperature monitoring-typically routed to an ADC input-to compensate for thermal drift in the main reference or system gain stages, as detailed in the Applications Information section of the Rev. S datasheet.
What is the long-term stability specification for ADR01BKSZ-REEL7?
The ADR01BKSZ-REEL7 exhibits 50 ppm long-term stability over 1000 hours of operation, as specified in Table 2 of the Rev. S datasheet. This value is noncumulative; subsequent 1000-hour periods show significantly lower drift, making it suitable for applications requiring multi-year calibration intervals without field adjustment.
Is ADR01BKSZ-REEL7 pin-compatible with REF01?
The ADR01BKSZ-REEL7 is not pin-compatible with REF01, which uses an 8-lead SOIC package. However, the ADR01 series' 8-lead SOIC variants (e.g., ADR01ARZ) are pin-to-pin compatible with REF01. The SC70-packaged ADR01BKSZ-REEL7 shares functional equivalence but requires PCB redesign due to its 5-pin, smaller footprint.
