Analog Devices Inc. AD5620BRJZ-1500RL7 Datasheet
Manufactured by Analog Devices, Inc., the AD5620BRJZ-1500RL7 belongs to the innovative nanoDAC family. It is a low-power, single, 12-bit buffered voltage-out digital-to-analog converter (DAC) that features a guaranteed monotonic design. This specific configuration integrates an on-chip 1.25 V, 5 ppm/°C precision reference, providing a full-scale rail-to-rail output voltage range of 2.5 V. Designed to minimize board space and current consumption without compromising on precision, it serves as a foundational component for advanced high-density circuitry.
The AD5620BRJZ-1500RL7 is currently In Stock and ready for immediate shipping at ICHOME. As a leading independent distributor, we ensure 100% original and rapid global delivery.

Supply Chain & Procurement Insights
Manufacturer: Analog Devices, Inc. (ADI)
Factory Lead Time: Factory leads times for ADI's legacy and high-demand analog-to-digital and digital-to-analog portfolios fluctuate heavily based on automotive and industrial allocation cycles. Normal factory lead times can often exceed 16 to 26 weeks during peak allocation periods.
ICHOME Advantage: To eliminate production line downtime, ICHOME leverages an established global supply network to maintain physical stock of the AD5620BRJZ-1500RL7. This allows us to bypass standard factory delays and fulfill urgent spot-buy requests with zero lead time.
Alternative Options & Replacements of AD5620BRJZ-1500RL7
When managing component shortages or implementing a multi-sourcing cross-reference strategy, consider these functional equivalents:
AD5620BRJZ-2500RL7: This is a drop-in pin-compatible variant with identical layout footprint. However, it incorporates an internal 2.5 V reference, yielding a full-scale output voltage range of 5 V under a 5 V supply instead of the 2.5 V full-scale range offered by the -1500RL7.
AD5660BRJZ-1500RL7: A high-resolution upgrade path within the exact same nanoDAC family and SOT-23 package. It ups the specification from 12 bits to 16 bits while retaining the 1.25 V internal reference. It serves as a drop-in replacement if your master controller firmware is updated to handle the 24-bit input shift register architecture.
Key Application of AD5620BRJZ-1500RL7
The precision output performance and ultra-low power consumption profiles render this device ideal for diverse global commercial and industrial applications:
Process Control & Industrial Automation: Used in loop-powered transmitters, isolated 4 mA to 20 mA programmable process controllers, and valve actuators.
Data Acquisition Systems (DAS): Provides reliable voltage offsets and high-accuracy reference tuning for multi-channel sensing networks.
Portable Battery-Powered Instruments: The sub-microamp power-down modes significantly extend battery longevity in field diagnostic tools.
Digital Gain and Offset Adjustments: Ideal for automated calibration systems requiring rail-to-rail precision trimming.
Outline Dimensions of AD5620BRJZ-1500RL7
The AD5620BRJZ-1500RL7 is housed in an ultra-compact 8-lead SOT-23 package (RJ-8 option), meticulously engineered to reduce footprint area in high-density multi-channel designs. Please refer to the official manufacturer mechanical drawing below for detailed standard dimensions, tolerance clearances, and precise pin-pitch configurations required for PCB layout engineering:
What is the difference between AD5620BRJZ-1500RL7 and AD5620ARJZ-1500RL7?
The critical differentiator lies in the linearity and relative accuracy grades assigned by the manufacturer. The B-Grade model (AD5620BRJZ) boasts a tighter Relative Accuracy rating of maximum±1 LSB INL. Conversely, the A-Grade model (AD5620ARJZ) exhibits a looser accuracy threshold of maximum ±6 LSB INL. For premium industrial automation designs, B-grade components are preferred.
