AD5662ARJ-2500RL7

Overview

The AD5662ARJ-2500RL7 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 requires an external reference voltage. The device guarantees 12-bit accuracy and monotonicity by design. Key electrical parameters include a maximum settling time of 10 μs, a typical power consumption of 250 μA at 5 V, and a power-down current of 480 nA at 5 V. It features a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards.

Feature Summary

• 16-bit resolution with guaranteed 12-bit accuracy and monotonic operation
• Rail-to-rail output swing with an integrated precision output amplifier
• Power-on reset circuitry providing zero-scale or midscale initialization
• Three software-selectable power-down modes reducing current to 480 nA

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 specific suffix '2' in the part number corresponds to the midscale power-on reset configuration as defined in the manufacturer's ordering guide. Confirm the package type matches the SOT-23-8 outline dimensions specified in the datasheet. Ensure the operating temperature range requirements align with the industrial grade specifications provided.

Selection Notes

Select this component when a low-power, high-resolution DAC is required for battery-operated devices. The external reference input allows flexibility in setting the output range. Consider the 10 μs settling time and 30 MHz serial clock speed for system timing constraints. The rail-to-rail output capability makes it suitable for single-supply applications requiring full dynamic range.

Part Context

This device belongs to the nanoDAC family, characterized by low power consumption and small footprint. It is designed for applications where space and energy efficiency are critical. The AD5662 utilizes a CMOS resistor string architecture to ensure monotonic performance without calibration.

Replacement Considerations

The AD5662x-1 variant offers a similar specification but powers up to zero scale instead of midscale. Other members of the nanoDAC family may offer different resolutions or internal reference options.
