AD5662ARJ-1500RL7

Overview

The AD5662ARJ-1500RL7 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 and monotonicity by design. It features an external reference input, rail-to-rail output swing, and a power-on reset circuit that initializes the output to zero scale. The part utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards.

Feature Summary

• 16-bit resolution with guaranteed 12-bit relative accuracy
• Low power consumption: 250 μA active, 480 nA in power-down
• Rail-to-rail output amplifier with remote sensing capability
• Power-on reset to zero scale or midscale options

Applications

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

Procurement Notes

Verify the specific suffix '1500' against the manufacturer's official ordering guide to confirm the exact power-on reset state and package variant. Ensure the selected revision matches the required automotive qualification status if applicable for the target environment.

Selection Notes

Select this component when a single-channel, high-resolution DAC is needed in a compact SOT-23 package. It requires an external reference voltage source. Verify that the system logic levels are compatible with the 3-wire serial interface requirements up to 30 MHz clock rates.

Part Context

This part belongs to the AD5662 nanoDAC series, which includes variants with internal references (AD5660/64/66) and different power-on reset behaviors. The 'ARJ' designation indicates the industrial temperature range (-40°C to +125°C) and SOT-23-8 packaging.

Replacement Considerations

Direct pin-compatible replacements within the same family include the AD5662BRJZ-2REEL7 (B Grade, Midscale Reset). For applications requiring an internal reference, consider the AD5660ARJZ-1REEL7.
