AD5662BRM-1REEL7

Overview

The AD5662BRM-1REEL7 is a single-channel, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family by Analog Devices. It operates on a single 2.7 V to 5.5 V supply and guarantees monotonicity by design. The device features a power-on reset circuit that initializes the output to zero scale, with a maximum settling time of 10 μs. It incorporates a versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, supporting clock rates up to 30 MHz. The part is housed in an 8-lead MSOP package and includes three software-selectable power-down modes to minimize current consumption.

Feature Summary

• 16-bit resolution with guaranteed 12-bit accuracy and rail-to-rail output swing
• Low power consumption: typically 250 μA at 5 V, reducing to 480 nA in power-down mode
• Power-on reset to zero scale for AD5662x-1 variants
• 3-wire serial interface with Schmitt-triggered inputs operating up to 30 MHz

Applications

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

Procurement Notes

Verify the specific suffix '1' indicates the power-on reset behavior corresponding to zero scale initialization. Confirm the 'B' grade specifications regarding relative accuracy and linearity errors against application requirements. Ensure the MSOP package thermal characteristics are suitable for the intended operating environment.

Selection Notes

Select this component when a single-channel, high-resolution DAC with low power consumption is required. The external reference input allows flexibility in setting the output range. Consider the 10 μs settling time and 30 MHz serial interface speed for system timing constraints. Verify compatibility with the host microprocessor's serial protocol standards.

Part Context

This part belongs to the AD5662 nanoDAC family, which offers various resolutions and channel counts. The AD5662 specifically provides 16-bit performance in a compact SOT-23 or MSOP package. Other family members include the AD5623/AD5663 (dual channel) and AD5624/AD5664 (quad channel), sharing similar interface and power characteristics.

Replacement Considerations

Direct replacements within the same family include the AD5662ARJ-2 (SOT-23 package, midscale reset) or AD5662BRMZ-1REEL7 (MSOP package). Cross-family alternatives like the AD5660 series offer internal references but may differ in pinout and power supply requirements.
