Product details
Overview
MAX516AEWG+ from Maxim Integrated is a 10-bit, single-channel voltage-output DAC with internal reference, housed in a 16-pin SOIC package, operating from a +4.5V to +5.5V supply, and featuring ±1 LSB integral nonlinearity (INL) over temperature. It is used in precision analog output control for industrial process controllers and programmable logic controller (PLC) analog modules.
For engineers reviewing the MAX516AEWG+ datasheet, MAX516AEWG+ pinout, MAX516AEWG+ application, or MAX516AEWG+ equivalent, key selection criteria include its rail-to-rail voltage output swing, monotonicity guarantee, internal 2.048V reference accuracy (±0.2%), and compatibility with SPI-compatible 3-wire serial interface at up to 5MHz clock rate.
Technical Context
The MAX516AEWG+ employs a segmented R-2R ladder architecture with on-chip trimming to achieve ±1 LSB INL and ±0.5 LSB differential nonlinearity (DNL). Its internal 2.048V bandgap reference provides stable excitation for the DAC core and supports external buffering or scaling via the REFOUT/REFIN pin.
It accepts serial data via a 3-wire SPI-compatible interface (CS, SCLK, DIN), supports power-down mode (1μA typical), and features a fast settling time of 10μs to ±0.5 LSB for full-scale step transitions at VDD = 5V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-output DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5300BRMZ-REEL7 | 8-bit resolution, internal 2.5V reference (±8ppm/°C drift), 10μs settling, same SOIC-16 package | Limited to lower-resolution control loops where 0.4% full-scale accuracy suffices | Select when cost sensitivity outweighs resolution requirement and 2.5V reference aligns with system scaling |
| MCP4921-E/SN | 12-bit resolution, external reference only, SPI interface, SOIC-8 package, no internal reference | Requires external precision reference and additional passive components; higher resolution but increased BOM and layout effort | Select when >10-bit resolution is mandatory and reference flexibility justifies added design overhead |
Compared with AD5300BRMZ-REEL7 and MCP4921-E/SN, the MAX516AEWG+ uniquely balances 10-bit accuracy, integrated 2.048V reference, and SOIC-16 footprint-reducing calibration dependency and board space while maintaining compatibility with legacy 5V industrial bus interfaces.

FAQ
What is the reference voltage accuracy of the MAX516AEWG+?
The MAX516AEWG+ features an internal 2.048V bandgap reference with ±0.2% initial accuracy over temperature (–40°C to +85°C). This specification is measured and guaranteed per Maxim's datasheet Rev. 1, and enables direct use in 0–5V or 0–10V output scaling without external trimming. The MAX516AEWG+ reference drift is ±25ppm/°C typical, supporting stable operation in unregulated industrial enclosures.
Does the MAX516AEWG+ require an external reference?
No, the MAX516AEWG+ does not require an external reference-it integrates a trimmed 2.048V bandgap reference accessible at the REFOUT/REFIN pin. However, that pin can also accept an external reference (1.2V to VDD) if system-level accuracy or voltage scaling demands differ. The MAX516AEWG+ operates fully functional with internal reference enabled by default.
What is the maximum SPI clock frequency supported by the MAX516AEWG+?
The MAX516AEWG+ supports a maximum SCLK frequency of 5MHz, as specified in the Absolute Maximum Ratings and AC Electrical Characteristics sections of its official datasheet. At this rate, the device reliably accepts 16-bit frames (start bit + 10-bit code + 6-bit command) with setup/hold timing met across the full operating temperature range. This allows the MAX516AEWG+ to sustain update rates exceeding 90 kSPS in continuous streaming mode.
Is the MAX516AEWG+ pin-compatible with other Maxim DACs like the MAX517 or MAX518?
No, the MAX516AEWG+ is not pin-compatible with the MAX517 or MAX518. While all three are 10-bit DACs in SOIC packages, the MAX516AEWG+ uses a 16-pin SOIC with dedicated PD (power-down) and REFOUT/REFIN pins, whereas the MAX517/MAX518 are 8-pin SOIC devices with different pin assignments and no internal reference. Pin mapping, supply requirements, and interface protocols differ-direct replacement requires PCB redesign. The MAX516AEWG+ pinout is unique to its functional configuration.
What is the output drive capability of the MAX516AEWG+?
The MAX516AEWG+ analog output (OUT pin) is internally buffered and specified to drive resistive loads ≥2kΩ with full rail-to-rail swing (0V to VDD). It is not rated for capacitive loads >100pF or low-impedance current sinking; external op-amp buffering is recommended for driving cables, ADC references, or 4–20mA loop transmitters. This output drive capability is confirmed in the MAX516AEWG+ DC Electrical Characteristics table under "Output Voltage Range" and "Load Regulation" parameters.
