AD5662BRJ-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 consumes 250 μA at 5 V. The device guarantees 12-bit accuracy and is monotonic by design. It features rail-to-rail output swing, a power-on reset circuit for zero-scale or midscale initialization, and three software-selectable power-down modes reducing current to 480 nA at 5 V. 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 12-bit accuracy and monotonicity
• Low power consumption: 250 μA active, down to 480 nA in power-down
• Rail-to-rail output amplifier with remote sensing capability via VFB pin
• Power-on reset to 0 V or midscale depending on suffix designation

Applications

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

Procurement Notes

Verify the ordering suffix matches the required power-on reset state. The '-1' suffix indicates a zero-scale power-up, while the '-2' suffix indicates a midscale power-up. Confirm package type and temperature grade specifications against project requirements before procurement.

Selection Notes

Select the AD5662BRJZ-2500RL7 when a single-channel 16-bit DAC with low power consumption is required. Ensure the external reference voltage meets the input range of 0.75 VDD to VDD. Verify that the system logic levels are compatible with the 3-wire serial interface timing requirements.

Part Context

This component belongs to the AD5662 nanoDAC family, which includes variants with different resolutions and channel counts. The BRJZ suffix denotes the B-grade performance level and SOT-23-8 packaging. The RL7 suffix typically indicates reel packaging quantity, though specific quantities should be verified with the distributor.

Replacement Considerations

Direct replacements within the same family include the AD5662ARJ-2500RL7 (A-grade) or AD5662KRJZ-2500RL7 (K-grade). Cross-family alternatives like the AD5640 or AD5660 offer internal references but differ in pinout and resolution options.
