Overview
The AD5693RARMZ 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 operates on a single 2.7 V to 5.5 V supply. The device guarantees monotonicity by design and offers high relative accuracy with ±2 LSB maximum INL at B grade. It utilizes an I2C serial interface for data transfer and includes a power-down mode reducing current consumption to 2 µA maximum. The component is housed in a compact 10-lead MSOP package.
Feature Summary
- 16-bit resolution with ±2 LSB maximum integral nonlinearity (INL) at B grade
- Internal 2.5 V reference with 2 ppm/°C typical temperature coefficient
- I2C serial interface supporting standard (100 kHz) and fast (400 kHz) modes
- Software-selectable output span of VREF or 2 × VREF
Applications
- Process controls
- Data acquisition systems
- Digital gain and offset adjustment
- Programmable voltage sources
- Optical modules
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout configuration and feature set. The AD5693RARMZ designation corresponds to the 10-lead MSOP package variant. Ensure compatibility with system voltage requirements and I2C bus specifications before integration.
Selection Notes
Select this component when a single-channel, high-precision 16-bit DAC is required in a small form factor. The internal reference simplifies design by eliminating external components, though external references can be used if lower noise or different voltage levels are needed. Verify that the I2C address configuration meets system addressing requirements.
Part Context
The AD5693RARMZ belongs to the AD5693R/AD5692R/AD5691R/AD5693 family of nanoDAC+ devices. This family shares common architecture and interface protocols but varies in resolution and reference configuration. The ARMZ suffix specifically identifies the MSOP package option within the broader product line.
Replacement Considerations
Direct replacements include other members of the nanoDAC+ family such as the AD5692R or AD5691R for lower resolution needs, or the AD5683R for SPI interface compatibility. Cross-referencing pinouts and electrical specifications is essential when substituting.
