AD5662ARJZ-1500RL7

Overview

The AD5662ARJZ-1500RL7 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 with typical current consumption of 250 μA at 5 V and 480 nA in power-down mode. The device guarantees 12-bit accuracy and monotonicity by design. It features rail-to-rail output swing, a 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards, and an external reference input. Available in an 8-lead SOT-23 package, it includes power-on reset options for zero-scale or midscale initialization.

Feature Summary

• 16-bit resolution with guaranteed 12-bit relative accuracy and monotonic operation
• Low power consumption: 250 μA active, down to 480 nA in power-down modes
• Rail-to-rail output amplifier with remote sensing capability via VFB pin
• 3-wire serial interface supporting clock rates up to 30 MHz

Applications

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

Procurement Notes

Verify that the suffix '1500' corresponds to the specific power-on reset configuration required for the application. Confirm the package type matches the PCB footprint requirements. Ensure the operating temperature range meets system specifications, as the Y version supports -40°C to +125°C. Check automotive qualification status if applicable to the end-use environment.

Selection Notes

Select this component when a single-channel, high-resolution DAC is needed in a compact SOT-23 package. Choose the '-1' variant for zero-scale power-up or '-2' for midscale, depending on system safety requirements. Ensure an external reference voltage source is available, as this model does not include an internal reference. Verify that the 3-wire interface timing aligns with the host microcontroller's capabilities.

Part Context

This part belongs to the AD5662 nanoDAC family, which offers low-power, small-footprint solutions for precision analog output applications. It shares architectural similarities with other members like the AD5620 and AD5640 but differs in resolution and reference integration. The ARJZ designation indicates the automotive-grade Y version in an SOT-23-8 package.

Replacement Considerations

Direct replacements within the same family include the AD5662ARJZ-1 (zero-scale reset) and AD5662ARJZ-2 (midscale reset). For different resolutions, consider the AD5620 (12-bit) or AD5640 (14-bit), noting changes in accuracy and code range. Cross-family replacements require verification of pin compatibility and interface protocols.
