Overview
The AD5683RACPZ-2RL7 is a single-channel, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features an internal 2.5 V reference with a typical drift of 2 ppm/°C and achieves ±2 LSB maximum integral nonlinearity (INL). The device operates on a single 2.7 V to 5.5 V supply with independent logic support down to 1.62 V. Key specifications include a 5 µs settling time, 0.1 nV-sec glitch impulse, and 20 mA drive capability. It utilizes a 3-wire SPI interface and is housed in an 8-lead LFCSP package.
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
- Programmable 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 control systems
- Data acquisition systems
- Digital gain and offset adjustment circuits
- Programmable voltage sources
Procurement Notes
Verify the specific suffix 'ACPZ-2RL7' against the manufacturer's ordering guide to confirm pin configuration options such as LDAC, VLOGIC, or RESET availability. Ensure the required grade (A or B) matches the application's linearity requirements, as INL specifications vary between grades.
Selection Notes
Select this component when a small footprint and high precision are required without external reference calibration. The internal 2.5 V reference eliminates the need for temperature compensation in many applications. Verify that the load impedance and capacitive requirements fall within the stability limits defined in the output characteristics table.
Part Context
This part belongs to the AD5683R/AD5682R/AD5681R/AD5683 nanoDAC+ portfolio. It shares architectural similarities with other members but offers unique 16-bit resolution and integrated reference capabilities compared to the external-reference AD5683 or lower-resolution variants.
Replacement Considerations
Direct pin-compatible replacements within the same family include AD5683RACPZ-1RL7 and AD5683RACPZ-RL7. Verify if the alternative suffix corresponds to the same pinout configuration and performance grade before substitution.
