Analog Devices Inc. ADR06BKS-R2

Overview

ADR06BKS-R2 from Analog Devices is a precision 3.0 V band gap voltage reference IC designed for high-stability analog signal chains in space-constrained systems. It delivers ±0.2% initial accuracy, 9 ppm/°C max temperature coefficient (B grade, SC70), 6 µV_p-p (0.1 Hz–10 Hz) noise, and operates from 5.0 V to 36.0 V supply across −40°C to +125°C - enabling use in industrial process control and precision data acquisition.

For engineers reviewing the ADR06BKS-R2 datasheet, ADR06BKS-R2 pinout, ADR06BKS-R2 application, or ADR06BKS-R2 equivalent, key selection considerations include its 3.0 V output stability under wide input voltage variation, low-noise performance without external capacitors, SC70-5 package footprint, and integrated TEMP pin for system-level temperature monitoring.

Technical Context

The ADR06BKS-R2 implements a trimmed band gap core with on-chip trimming for high initial accuracy and low thermal drift. Its five-terminal architecture includes dedicated VIN, VOUT, GND, TRIM, and TEMP pins - enabling both output fine-tuning and calibrated temperature sensing via a 1.96 mV/°C linear output at the TEMP pin.

It supports 10 mA output current with 2 V dropout, exhibits 7–30 ppm/V line regulation and 40–70 ppm/mA load regulation over temperature, and achieves 4 µs turn-on settling time - making it suitable for dynamic power-rail monitoring and high-resolution ADC biasing where fast stabilization and minimal supply sensitivity are required.

FAQ

What is the output voltage tolerance of the ADR06BKS-R2 at room temperature?

The ADR06BKS-R2 has a nominal output voltage of 3.000 V with an initial accuracy of ±6 mV (±0.2%) at 25°C for the B grade. This specification is guaranteed across the full SC70-5 package variant and applies before any TRIM adjustment. The device maintains this tolerance over its entire operating temperature range of −40°C to +125°C, supported by its 9 ppm/°C maximum temperature coefficient.

Does the ADR06BKS-R2 require external capacitors for stability?

No, the ADR06BKS-R2 is internally compensated and operates stably with zero input or output capacitance. This eliminates the need for external bypass or filter capacitors, reducing bill-of-materials count and avoiding potential instability from capacitor ESR or aging effects. The design maintains specified noise, line regulation, and transient response without external components.

How is the TEMP pin on the ADR06BKS-R2 used in practice?

The TEMP pin on the ADR06BKS-R2 outputs a factory-calibrated 550 mV at 25°C with a linear 1.96 mV/°C slope, enabling direct ratiometric temperature measurement. Engineers connect it to an ADC input to derive die temperature - useful for thermal compensation of sensor offsets or system-level fault detection. No external resistors or calibration are needed for basic monitoring.

What is the maximum supply voltage the ADR06BKS-R2 can tolerate?

The ADR06BKS-R2 has an absolute maximum supply voltage rating of 36.0 V, with a recommended operating range of 5.0 V to 36.0 V. It sustains full electrical specifications across this range, including 7–30 ppm/V line regulation and stable 3.0 V output. This makes it compatible with unregulated 12 V and 24 V industrial rails and resilient against common automotive load-dump transients.

Is the ADR06BKS-R2 pin-compatible with other members of the ADR0x family?

The ADR06BKS-R2 shares identical pinout and function mapping with ADR01/ADR02/ADR03 in the same SC70-5 package - VIN, VOUT, GND, TRIM, and TEMP pins occupy identical positions and serve identical roles. However, output voltage differs (3.0 V vs. 10.0/5.0/2.5 V), so direct substitution requires verification of downstream circuit voltage tolerances.
