Product details
Overview
MAX516BENG+ from Maxim Integrated is a 12-bit, single-channel, voltage-output digital-to-analog converter (DAC) with internal 2.048V reference, rail-to-rail output, and SPI-compatible 3-wire serial interface. It operates from a +2.7V to +5.5V supply, delivers ±1 LSB INL, and is used in precision industrial control loops and sensor calibration circuits.
For engineers reviewing the MAX516BENG+ datasheet, MAX516BENG+ pinout, MAX516BENG+ application, or MAX516BENG+ equivalent, key selection considerations include its guaranteed monotonicity, low-glitch energy (0.1 nV·s), integrated reference accuracy (±0.2% initial), and operation over the –40°C to +85°C temperature range.
Technical Context
The MAX516BENG+ implements a segmented R-2R ladder architecture with on-chip 2.048V bandgap reference, enabling stable full-scale output of 0–2.048V without external components. Its SPI-compatible serial interface supports clock rates up to 10MHz and includes independent LDAC and CLR inputs for synchronous update and zero-scale reset.
It features power-on reset that ensures the DAC output powers up at zero volts, and a shutdown mode reducing supply current to 1µA. The device is specified for monotonicity across the entire 0°C to 70°C commercial temperature range and maintains ±1 LSB DNL over –40°C to +85°C.
Key Specifications

| Output Type | Voltage-output, rail-to-rail - delivers 0V to VREF (2.048V) with no headroom loss |
| Reference | Internal 2.048V ±0.2% - eliminates need for external reference and reduces BOM count |
| INL | ±1 LSB max - ensures accurate transfer function across full code range |
| Supply Voltage | +2.7V to +5.5V - compatible with 3.3V and 5V logic/system rails |
| Temperature Range | –40°C to +85°C - qualified for industrial ambient environments |
Pinout & Package
MAX516BENG+ is housed in a 16-pin narrow SO package (SO16N) with 1.27mm pitch, JEDEC MS-012AC compliant, and rated for 260°C reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply | Accepts +2.7V to +5.5V; powers internal reference and DAC core |
| GND | Ground reference | Analog and digital ground common point; requires low-impedance connection |
| REF | Reference input/output | Internally connected to 2.048V reference; can be overdriven or bypassed |
| OUT | Analog output | Rail-to-rail buffered voltage output; drives loads ≥2kΩ |
| DIN | Serial data input | CMOS-compatible SPI data input (MSB-first, 16-bit frame) |
| SCLK | Serial clock input | Accepts up to 10MHz clock; controls data latching timing |
| LDAC | Load DAC input | Active-low asynchronous latch; updates output when pulled low |
| CLR | Clear input | Active-low reset; forces output to zero scale regardless of register content |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 2.048V reference | Eliminates external reference component and associated layout sensitivity |
| Low-glitch energy (0.1 nV·s) | Minimizes transient disturbance during code transitions-critical for closed-loop stability |
| Power-on reset to zero | Guarantees safe startup state; prevents undefined output at system boot |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5320BRMZ-REEL7 | 12-bit, voltage-output DAC with internal 2.5V reference; no CLR pin; SPI interface only | Lacks hardware reset; requires software-initiated zeroing; reference voltage differs | Choose AD5320BRMZ-REEL7 if 2.5V full-scale output is acceptable and CLR functionality is not required |
| MCP4921-E/P | 12-bit, voltage-output DAC with external reference dependency; no internal reference; uses SPI with LDAC but no CLR | Requires external precision reference; higher BOM cost and layout sensitivity | Choose MCP4921-E/P where reference flexibility (e.g., 4.096V scaling) outweighs integration benefit |
Compared with AD5320BRMZ-REEL7 and MCP4921-E/P, the MAX516BENG+ uniquely combines internal 2.048V reference, hardware CLR, rail-to-rail output, and guaranteed monotonicity-making it optimal for industrial systems requiring deterministic startup and minimal external components.

FAQ
What is the reference voltage specification for the MAX516BENG+?
The MAX516BENG+ integrates a precision 2.048V bandgap reference with ±0.2% initial accuracy and ±30ppm/°C temperature coefficient. This reference sets the full-scale output range and eliminates the need for external reference components, simplifying design and improving long-term stability in the MAX516BENG+.
Does the MAX516BENG+ support true rail-to-rail output swing?
Yes, the MAX516BENG+ delivers rail-to-rail output voltage swing from 0V to VREF (2.048V) under load conditions ≥2kΩ. Its output buffer is designed to drive to both supply rails without headroom loss, ensuring full utilization of the 12-bit resolution in the MAX516BENG+.
What is the maximum SPI clock frequency supported by the MAX516BENG+?
The MAX516BENG+ supports SPI serial clock frequencies up to 10MHz, enabling fast data loading and rapid output updates. This allows the MAX516BENG+ to respond within microseconds to new digital codes, supporting dynamic control applications such as waveform generation and real-time calibration.
How does the CLR pin function in the MAX516BENG+?
The CLR (Clear) pin on the MAX516BENG+ is an active-low hardware reset that forces the DAC output to zero volts regardless of the contents of the input register. This provides deterministic startup and fast recovery from fault conditions in the MAX516BENG+, unlike software-only reset methods.
Is the MAX516BENG+ pin-compatible with other devices in the MAX516 family?
Yes, the MAX516BENG+ shares identical pinout and package (16-pin SO) with all members of the MAX516 family, including MAX516AENG+ and MAX516CENG+. Differences between variants are limited to grade-specific specifications (e.g., INL, DNL, temperature range), not connectivity-ensuring drop-in replacement capability within the same MAX516BENG+ family.
