AD5662ARM-1REEL7

Overview

The AD5662ARM-1REEL7 is a single-channel, 16-bit digital-to-analog converter (DAC) from the nanoDAC family by Analog Devices. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and features a rail-to-rail buffered output amplifier. The device guarantees 12-bit accuracy and is monotonic by design. It utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 30 MHz. Key power specifications include a typical consumption of 250 μA at 5 V in normal mode and reduced current down to 480 nA in power-down modes. The part incorporates a power-on reset circuit that initializes the output to zero scale.

Feature Summary

• 16-bit resolution with guaranteed 12-bit relative accuracy and monotonicity by design
• Rail-to-rail output swing with an integrated precision output buffer amplifier
• Low power consumption: 250 μA typical at 5 V; power-down currents as low as 100 nA at 3 V
• Power-on reset function available for zero scale or midscale initialization

Applications

• Process control systems requiring precise analog signal generation
• Portable battery-powered instruments due to low power profile
• Data acquisition systems needing high-resolution voltage outputs
• Programmable voltage and current sources
• Digital gain and offset adjustment circuits

Procurement Notes

Verify the ordering suffix '-1' confirms the power-on reset behavior targets zero scale upon startup. Confirm the package designation 'ARM' corresponds to the 8-lead MSOP form factor. Ensure the reel packaging matches production requirements. Cross-reference the specific grade (A or B) against application linearity needs, as accuracy specifications vary between grades.

Selection Notes

Select this component when a single-channel, high-resolution DAC is required in a compact surface-mount package. The external reference requirement allows flexibility in setting the output range. Consider the 10 μs settling time and 30 MHz serial interface speed for system timing constraints. Evaluate the power-down modes if energy efficiency during idle states is critical for the application.

Part Context

This part belongs to the AD5662 nanoDAC family, which offers 16-bit resolution in small packages. The '-1' suffix distinguishes it from variants like the '-2', which resets to midscale. It shares architectural similarities with other members such as the AD5660 and AD5640 but differs in reference integration and package options. The device is designed for applications demanding precision and low power in space-constrained environments.

Replacement Considerations

Direct replacements within the same family include the AD5662ARJZ-2REEL7, though it resets to midscale instead of zero scale. For identical reset behavior, verify availability of other AD5662 variants with the '-1' suffix in different packages, such as the AD5662BRMZ-1REEL7 in MSOP.
