Overview
The AD5662BRJZ-2REEL7 is a single-channel, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family. It operates on a single supply ranging from 2.7 V to 5.5 V and consumes 250 μA at 5 V. The device guarantees 12-bit accuracy with ±8 LSB relative accuracy for the B grade and features rail-to-rail output swing. It incorporates an external reference input, power-on reset to midscale, and three software-selectable power-down modes reducing current to 480 nA at 5 V. The component utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards.
Feature Summary
- 16-bit resolution with guaranteed monotonicity by design
- Low power consumption: 250 μA active, 480 nA in power-down mode
- Rail-to-rail output amplifier with remote sensing capability via VFB pin
- Power-on reset circuit ensures output initializes to midscale
Applications
- Process control systems
- Portable battery-powered instruments
- Programmable voltage and current sources
- Digital gain and offset adjustment circuits
Procurement Notes
Verify that the specific suffix '2' corresponds to the midscale power-on reset configuration required for the application. Confirm the package type matches the SOT-23-8 footprint requirements. Ensure the external reference voltage source meets the specified input range of 0.75 VDD to VDD for optimal linearity performance.
Selection Notes
Select this part when a single-channel 16-bit DAC with low power consumption is needed. The B grade offers ±8 LSB relative accuracy compared to the A grade's ±32 LSB. Choose this model over the -1 variant if the system requires the DAC output to initialize to midscale upon power-up rather than zero scale.
Part Context
This component belongs to the AD5662 nanoDAC family, which includes variants with internal references such as the AD5620/AD5640/AD5660. Unlike those models, the AD5662 requires an external reference voltage to define its output range. It shares the same 8-lead SOT-23 and MSOP packaging options within the family.
Replacement Considerations
The AD5662ARJ-2 serves as a functional equivalent within the same family, offering identical specifications but potentially different grading or packaging availability.
