AD5662BRM-1

Overview

The AD5662BRM-1 is a single-channel, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family. It operates on a single 2.7 V to 5.5 V supply and consumes 250 μA at 5 V. The device features rail-to-rail output swing and guarantees 16-bit monotonicity by design. It incorporates a power-on reset circuit that sets the output to zero scale for the -1 suffix variant. The part utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 30 MHz.

Feature Summary

• 16-bit resolution with guaranteed monotonic operation
• Rail-to-rail buffered voltage output
• Low power consumption: 250 μA active, 480 nA in power-down
• Power-on reset to zero scale (-1 suffix)
• 3-wire serial interface with SYNC interrupt

Applications

• Process control systems
• Portable battery-powered instruments
• Programmable voltage and current sources
• Digital gain and offset adjustment
• Data acquisition systems

Procurement Notes

Verify the ordering suffix 'BRM-1' against the manufacturer's official documentation to confirm package type (MSOP), temperature grade (Industrial/B Grade), and power-on reset behavior (Zero Scale). Ensure compatibility with system requirements for external reference voltage selection and serial interface timing constraints.

Selection Notes

Select this component for applications requiring high resolution and low power in a small footprint. The -1 suffix indicates a power-on reset to 0 V; use the -2 suffix if mid-scale initialization is required. An external reference voltage must be provided to define the output range. Verify that the load capacitance does not exceed stability limits without series resistance.

Part Context

The AD5662 belongs to Analog Devices' nanoDAC family of low-power, single-supply DACs. This specific model represents the B-grade version in an MSOP-8 package with industrial temperature rating. It shares architectural similarities with other members like the AD5660 and AD5663 but differs in channel count and internal reference availability.

Replacement Considerations

Direct replacements within the same family include the AD5662ARJ-2 (SOT-23 package, midscale reset) or AD5662ARMZ-1 (MSOP package, zero scale reset). Cross-package substitutions require verification of pinout compatibility and thermal performance.
