AD5662BRJZ-2500RL7

Overview

The AD5662BRJZ-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 draws 250 μA at 5 V. The device guarantees 12-bit accuracy with ±8 LSB INL and ±1 LSB DNL. It features rail-to-rail output swing, a power-on reset to midscale, and three software-selectable power-down modes reducing current to 480 nA at 5 V. The part uses a versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards.

Feature Summary

• 16-bit resolution with guaranteed monotonicity by design
• Low power consumption: 250 μA active, 480 nA in power-down
• Rail-to-rail output amplifier with remote sensing capability via VFB pin
• Power-on reset circuit ensures output starts at midscale

Applications

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

Procurement Notes

Verify the specific suffix '2500' against the manufacturer's official ordering guide to confirm it denotes the midscale power-on reset variant. Ensure the package type matches the required PCB footprint, as this model is available in SOT-23 and MSOP packages. Confirm RoHS compliance status for the specific manufacturing lot.

Selection Notes

Select this component when a single-channel, high-resolution DAC with low power consumption is required. The external reference input allows flexibility in setting the output range. Ensure the application supports the 3-wire serial interface timing requirements, specifically the SYNC interrupt functionality and clock rates up to 30 MHz.

Part Context

This part belongs to the AD5662 nanoDAC family, which includes variants with different power-on reset behaviors (zero scale vs. midscale). The BRJZ suffix indicates an automotive-grade qualification and a SOT-23-8 package. Other family members include the AD5663 (dual channel) and AD5664 (quad channel).

Replacement Considerations

Direct replacements within the same family include the AD5662ARJZ-2500RL7 (industrial grade) or AD5662BRMZ-2REEL7 (MSOP package). Verify that the replacement maintains the midscale power-on reset characteristic and the same serial interface compatibility.
