Analog Devices Inc. ADR01BRZ

Overview

ADR01BRZ from Analog Devices is a precision 10.0 V band gap voltage reference IC with ±0.05% initial accuracy, 3 ppm/°C typical temperature coefficient (8-lead SOIC, A grade), and 10 mA output current capability. It operates from 12.0 V to 36.0 V supply, supports −40°C to +125°C industrial temperature range, and includes dedicated TEMP and TRIM pins for temperature monitoring and output fine-tuning-used in high-resolution ADC biasing and precision instrumentation power rails.

For engineers reviewing the ADR01BRZ datasheet, ADR01BRZ pinout, ADR01BRZ application, or ADR01BRZ equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options-all grounded in Analog Devices' Rev. S datasheet and official ordering information.

Technical Context

The ADR01BRZ implements a thermally compensated band gap core with internal trimming to achieve low drift and high DC stability. Its TEMP pin provides a ratiometric 550 mV baseline with 1.96 mV/°C sensitivity, enabling on-chip temperature sensing without external components. The TRIM pin allows ±0.5% output adjustment via external resistor network.

Designed for wide-input-voltage operation, it maintains regulation down to 2 V dropout and delivers 20 µV_p-p (0.1 Hz–10 Hz) noise performance. Line regulation is specified at 7–30 ppm/V and load regulation at 40–70 ppm/mA across full temperature range, supporting stable reference delivery in noisy industrial power environments.

FAQ

What is the maximum input voltage rating for ADR01BRZ?

The ADR01BRZ has an absolute maximum supply voltage of 36.0 V, with recommended operating range from 12.0 V to 36.0 V. Exceeding 36.0 V risks permanent damage per Absolute Maximum Ratings table. The device maintains regulation down to 2 V dropout, so minimum functional VIN is 12.0 V for 10.0 V output. This wide range allows direct use with 24 V industrial rails and automotive batteries without pre-regulation.

Does ADR01BRZ require an external output capacitor?

No, the ADR01BRZ is internally compensated and does not require an external output capacitor for stability under any load condition up to 10 mA. This is explicitly stated in the Features section and confirmed in Applications Information. Adding capacitance may degrade transient response or cause oscillation-Analog Devices recommends leaving VOUT unfiltered unless specific noise-reduction needs justify a small ceramic cap (<100 nF) with careful layout.

What is the function of the TEMP pin on ADR01BRZ?

The TEMP pin on ADR01BRZ outputs a ratiometric voltage of 550 mV at 25°C with a linear sensitivity of 1.96 mV/°C across −40°C to +125°C. It enables on-chip temperature monitoring without external sensors-used for thermal compensation of system gain/offset or as a diagnostic indicator. The output is buffered and independent of VOUT loading, allowing simultaneous use as reference and sensor.

Is ADR01BRZ pin-compatible with REF01?

Yes, the ADR01BRZ in 8-lead SOIC package is pin-to-pin compatible with the industry-standard REF01, including identical VIN, VOUT, GND, and TRIM pin assignments. The ADR01BRZ adds a functional TEMP pin (Pin 3) not present in REF01, but REF01 leaves that location unconnected-so ADR01BRZ can directly replace REF01 without layout changes, gaining temperature sensing capability.

What grade and package does ADR01BRZ correspond to?

ADR01BRZ denotes the B-grade (±0.05% initial accuracy), 8-lead SOIC (R-8) package variant of the ADR01 10.0 V reference. The "B" suffix specifies the accuracy grade; "RZ" indicates tape-and-reel packaging in SOIC-8. It is not the SC70 or TSOT variant-those use different suffixes (e.g., ADR01BUJZ for TSOT-5). This grade/package combination is qualified for industrial and automotive applications.
