AD5662BRMZ-1REEL7

Overview

The AD5662BRMZ-1REEL7 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 with ±8 LSB INL and ±1 LSB DNL for B grade. It features rail-to-rail output swing, a power-on reset to zero scale, and three software-selectable power-down modes reducing current to 480 nA at 5 V. The part uses 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 amplifier with remote sensing capability via VFB pin
• Power-on reset circuit ensures output starts at 0 V (suffix -1)
• Three power-down modes: 1 kΩ to GND, 100 kΩ to GND, or three-state

Applications

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

Procurement Notes

Verify the ordering suffix '-1' confirms the power-on reset behavior to zero scale rather than midscale. Confirm the 'B' grade designation matches required linearity specifications of ±8 LSB INL. Ensure the MSOP-8 package variant aligns with PCB footprint constraints. Check RoHS compliance status as per manufacturer documentation.

Selection Notes

Select this component when a single-channel 16-bit DAC with low power consumption is required. The external reference input allows flexibility in setting output range. Consider the 10 μs settling time for speed requirements. The B grade offers tighter linearity than A grade but wider than Y version. Verify supply voltage range compatibility with system rails.

Part Context

This part belongs to the AD5662 nanoDAC family, which includes variants with internal references (AD5620/AD5640/AD5660) and different power-on reset behaviors (AD5662x-2 resets to midscale). The BRMZ-1REEL7 specifically denotes the B grade, MSOP-8 package, zero-scale reset, and reel packaging.

Replacement Considerations

Direct substitutes include other AD5662 variants with adjusted grades or reset behaviors. For single-channel 16-bit DACs with similar interfaces, consider AD5663 (dual channel) or AD5665 (quad channel) if more channels are needed. Verify pinout compatibility for MSOP-8 packages.
