Overview
The AD5683RBCPZ-RL7 is a single-channel, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features a maximum integral nonlinearity (INL) of ±2 LSB and includes an enabled-by-default internal 2.5 V reference with a typical drift of 2 ppm/°C. The device operates on a single 2.7 V to 5.5 V supply and supports a selectable output span of 0 V to VREF or 0 V to 2 × VREF. It utilizes a versatile 3-wire SPI serial interface compatible with standard modes and guarantees monotonicity by design.
Feature Summary
- 16-bit resolution with ±2 LSB maximum INL for high relative accuracy
- Integrated 2.5 V reference with 2 ppm/°C typical temperature coefficient
- Selectable output span: 0 V to VREF or 0 V to 2 × VREF
- Low power consumption: 1.2 mW at 3.3 V; 2 µA max in power-down mode
Applications
- Process controls
- Data acquisition systems
- Digital gain and offset adjustment
- Programmable voltage sources
Procurement Notes
Verify the B grade designation confirms the ±2 LSB INL specification. Confirm the -RL7 suffix indicates reel packaging. Ensure the specific pin configuration variant (LDAC, VLOGIC, or RESET options) matches the target schematic requirements before procurement.
Selection Notes
Select this component when a single-channel 16-bit DAC with integrated low-drift reference is required. The AD5683R differs from the AD5683 by including the internal reference. Verify that the 2 mm × 2 mm LFCSP package fits the board space constraints and that the 50 MHz SPI clock rate meets system timing requirements.
Part Context
This part belongs to the AD5683R/AD5682R/AD5681R/AD5683 nanoDAC+ portfolio. It is the 16-bit version with an internal reference, distinct from the AD5683 which requires an external reference. It shares the same ultrasmall 8-lead LFCSP package as the 14-bit and 12-bit variants in the series.
Replacement Considerations
The AD5683BCPZ-RL7 is a related part but lacks the internal reference. Direct functional replacement requires verifying if the system provides an external reference suitable for the AD5683.
