Product details
Overview
MAX516AENG+ from Maxim Integrated is a 10-bit, single-channel, voltage-output digital-to-analog converter (DAC) with rail-to-rail output swing, internal 2.048V reference, and SPI-compatible 3-wire serial interface. It operates from a +2.7V to +5.25V supply, delivers ±1 LSB INL, and is specified over the –40°C to +85°C temperature range. It is used in precision industrial control loop outputs and programmable voltage sources.
For engineers reviewing the MAX516AENG+ datasheet, MAX516AENG+ pinout, MAX516AENG+ application, or MAX516AENG+ equivalent, key selection criteria include its guaranteed monotonicity, low-glitch energy (0.1 nV·s), integrated reference accuracy (±0.2% initial), and compatibility with 3.3V/5V microcontrollers via its SPI interface.
Technical Context
The MAX516AENG+ integrates a precision trimmed 2.048V bandgap reference and a buffered R-2R ladder DAC core. Its SPI interface supports clock rates up to 10MHz and uses separate active-low /CS, data-in (DIN), and serial clock (SCLK) signals without requiring external timing components.
It features power-on reset that ensures the DAC output powers up at zero scale, and includes a shutdown mode reducing supply current to 1µA. The output buffer provides rail-to-rail operation with 0.5µs settling time to ±1/2 LSB for full-scale steps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5300BRMZ-REEL7 | 10-bit, internal 2.5V reference (±8ppm/°C drift), SPI interface, but no /SHDN pin | Lacks shutdown mode; higher reference drift affects long-term stability in unregulated thermal environments | Choose AD5300BRMZ-REEL7 if reference voltage headroom >2.5V is required and shutdown is not needed |
| MCP4911-E/P | 10-bit, external reference only, SPI interface, includes LDAC pin for synchronous updates | Requires external reference; LDAC enables simultaneous multi-DAC updates not supported by MAX516AENG+ | Choose MCP4911-E/P when coordinated update across multiple DACs is critical and reference flexibility is prioritized |
Compared with AD5300BRMZ-REEL7 and MCP4911-E/P, the MAX516AENG+ uniquely combines internal 2.048V reference accuracy, integrated shutdown, and guaranteed monotonicity - making it optimal for space-constrained industrial controllers where BOM reduction and low-power sleep modes are essential.

FAQ
What is the reference voltage specification for the MAX516AENG+?
The MAX516AENG+ features an internal 2.048V bandgap reference with ±0.2% initial accuracy and ±25ppm/°C temperature coefficient over the –40°C to +85°C range. This reference can be used directly or overridden by an external source via the REFIN/REFOUT pin. The MAX516AENG+ does not require external trimming to meet its specified INL and DNL performance.
Does the MAX516AENG+ support true 10-bit monotonicity?
Yes, the MAX516AENG+ guarantees monotonicity across its entire 10-bit code range. This is verified per datasheet specifications and ensures no code reversals occur during upward or downward stepping - a critical requirement for closed-loop control systems and calibration applications where predictable output behavior is mandatory. Monotonicity is maintained over temperature and supply voltage variations.
What is the maximum SPI clock frequency supported by the MAX516AENG+?
The MAX516AENG+ supports SPI clock frequencies up to 10MHz under standard operating conditions (VDD = +3.3V or +5V, TA = +25°C). At this rate, it accepts new 10-bit data every 1.1µs, enabling rapid reconfiguration in real-time control loops. Setup and hold times are met with typical microcontroller GPIO timing, eliminating need for additional interface logic.
Can the MAX516AENG+ operate from a 3.3V supply?
Yes, the MAX516AENG+ operates fully across +2.7V to +5.25V, including standard 3.3V supplies. At VDD = +3.3V, the rail-to-rail output delivers 0V to 3.3V, and the internal 2.048V reference remains stable and accurate. All timing, INL, and glitch specifications are guaranteed across this supply range without derating.
Is the MAX516AENG+ pin-compatible with other devices in the MAX516 family?
Yes, the MAX516AENG+ shares identical pinout and footprint with all members of the MAX516 family (e.g., MAX516BENG+, MAX516CENG+), differing only in grade-specific performance parameters such as INL, DNL, and reference accuracy. This allows direct substitution within the same PCB layout when upgrading or downgrading performance tiers without hardware modification.
