AD5680BRJZ-1REEL7

Overview

The AD5680BRJZ-1REEL7 is a single-channel, 18-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 4.5 V to 5.5 V supply and features an 8-lead SOT-23 package. The device guarantees 12-bit accuracy with 18-bit monotonicity. It incorporates a power-on reset circuit that ensures the output powers up to zero scale (0 V). The DAC utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, supporting clock rates up to 30 MHz. Power consumption is typically 1.6 mW at 5 V.

Feature Summary

• 18-bit resolution with guaranteed 12-bit accuracy
• Power-on reset to zero scale for AD5680-1 variant
• Rail-to-rail output swing in 8-lead SOT-23 package
• 3-wire serial interface with 30 MHz clock capability

Applications

• Closed-loop process control
• Low bandwidth data acquisition systems
• Portable battery-powered instruments
• Gain and offset adjustment circuits
• Precision setpoint control

Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm the power-on reset state. The AD5680-1 designation indicates a zero-scale power-up, whereas other variants may default to midscale. Ensure the reel packaging matches production requirements. Confirm RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component when high resolution is required in a minimal footprint. The external reference input allows flexibility in setting the output range. Consider the 1.6 mW power consumption for battery-operated designs. Verify that the 3-wire interface timing meets the host microcontroller's specifications. Ensure the load capacitance remains within stability limits for the desired settling time.

Part Context

The AD5680 belongs to the nanoDAC family, designed for precision applications requiring small form factors. It shares architectural similarities with other members like the AD5662 but offers higher resolution. The BRJZ-1 suffix denotes the B grade temperature range, SOT-23 package, and zero-scale power-on reset functionality. This part is distinct from ADCs or multi-channel DACs in the same portfolio.

Replacement Considerations

The AD5662 is a comparable 16-bit alternative in the same package. Check pin compatibility and resolution requirements when substituting. Verify that the replacement supports the required serial interface protocol and power supply range.
