AD5662BRJ-1500RL7

Overview

The AD5662BRJ-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 consumes 250 μA at 5 V. The device features rail-to-rail output swing with a slew rate of 1.5 V/μs and a maximum settling time of 10 μs. It guarantees 12-bit accuracy and monotonicity by design. The part utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, supporting clock rates up to 30 MHz. It includes power-on reset options and three software-selectable power-down modes.

Feature Summary

• 16-bit resolution with guaranteed 12-bit accuracy and monotonic operation
• Low power consumption: 250 μA active, down to 480 nA in power-down mode
• Rail-to-rail output amplifier with 1.5 V/μs slew rate
• 3-wire serial interface supporting up to 30 MHz clock speed

Applications

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

Procurement Notes

Verify that the ordering suffix '1500RL7' corresponds to the specific reel quantity and tape-and-reel packaging configuration required for automated assembly. Confirm the grade (B Grade) matches the application's linearity requirements. Ensure the automotive qualification status aligns with system reliability standards if used in vehicular environments.

Selection Notes

Select this component when a single-channel, high-resolution DAC is needed in a compact SOT-23 package. The AD5662x-1 variant powers up to 0 V, while the AD5662x-2 variant powers up to midscale; verify the specific suffix determines the power-on state. Ensure the external reference voltage source can supply the required 75 μA input current at 5 V.

Part Context

The AD5662 belongs to Analog Devices' nanoDAC family, designed for low-power, space-constrained applications. It serves as a single-channel counterpart to quad-channel variants like the AD5317. The BRJ-1500RL7 designation indicates a B-grade device in an 8-lead SOT-23 package, supplied in reels of 1500 units.

Replacement Considerations

Direct pin-compatible replacements within the same package include other AD5662 variants with different power-on reset states or grades. For quad-channel needs, consider the AD5317 series. Verify that substitute parts maintain the 30 MHz serial clock limit and 2.7 V minimum supply voltage.
