Overview
The AD5662BRJ-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 guarantees monotonicity by design. The device features a low power consumption of 250 μA at 5 V and includes a power-on reset circuit that ensures the output powers up to zero scale. It utilizes 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 SOT-23 package.
Feature Summary
- 16-bit resolution with guaranteed 12-bit accuracy and monotonic operation
- Rail-to-rail output swing with an integrated precision output amplifier
- Power-on reset to zero scale for safe startup conditions
- Three software-selectable power-down modes reducing current to 480 nA at 5 V
Applications
- Process control systems
- Portable battery-powered instruments
- Programmable voltage and current sources
- Digital gain and offset adjustment circuits
Procurement Notes
Verify the suffix '1' confirms the power-on reset behavior targets zero scale rather than midscale. Confirm the 'R' indicates the SOT-23 package variant. Ensure the 'EEL7' designation matches the required reel packaging specifications for automated assembly processes.
Selection Notes
Select this component when a single-channel 16-bit DAC with rail-to-rail output is required in a minimal footprint. 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.
Part Context
This part belongs to the AD5662 family of nanoDACs. The BRJ suffix denotes the B grade performance level and the SOT-23 package. The '-1' suffix specifies the power-on reset state as zero scale, distinguishing it from the '-2' variant which resets to midscale.
Replacement Considerations
The AD5662ARJ-2 serves as a functional alternative within the same family but differs in its power-on reset behavior, initializing to midscale instead of zero scale. Verify package compatibility and reset requirements before substitution.
