AD5662BRJZ-1REEL7

Overview

The AD5662BRJZ-1REEL7 is a single-channel, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices' 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. The device features rail-to-rail output swing and an external reference input. It includes a power-on reset circuit that initializes the output to zero scale for the -1 suffix variant. The DAC utilizes a 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 monotonicity by design
• Rail-to-rail output buffer amplifier
• Power-on reset to zero scale (AD5662x-1)
• Three software-selectable power-down modes
• 3-wire serial interface with SYNC interrupt

Applications

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

Procurement Notes

Verify the ordering suffix against the manufacturer's official documentation to confirm specific package type and initial output state. Confirm RoHS compliance status through authorized distributors or direct manufacturer channels prior to procurement.

Selection Notes

Select this component when a single-channel 16-bit DAC with low power consumption and rail-to-rail output is required. Ensure an external reference voltage source is available as the part does not contain an internal reference. Verify that the system logic levels are compatible with the specified VINH/VINL thresholds.

Part Context

This part belongs to the AD5662 nanoDAC series, which offers various configurations including different power-on reset states (-1 for zero scale, -2 for midscale) and packages (SOT-23, MSOP). The BRJZ designation indicates a specific temperature grade and packaging configuration within this family.

Replacement Considerations

Direct replacements include other AD5662 variants such as AD5662ARJZ-1REEL7 or AD5662BRMZ-1REEL7, provided pin compatibility and electrical specifications match the application requirements.
