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 single +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 sensor calibration circuitry.
For engineers reviewing the MAX516AENG datasheet, MAX516AENG pinout, MAX516AENG application, or MAX516AENG equivalent, key selection criteria include its integrated reference accuracy, monotonicity guarantee, SPI timing compatibility, and SO-8 package thermal performance in closed-loop analog output stages.
Technical Context
The MAX516AENG implements a resistor-string DAC architecture with buffered voltage output, ensuring monotonicity across full scale. Its internal 2.048V reference has ±0.2% initial accuracy and 3 ppm/°C temperature coefficient, enabling stable output without external trimming.
It supports standard SPI mode 0 (CPOL = 0, CPHA = 0) with 16-bit frame format: 4-bit command + 10-bit data + 2-bit don't-care. The /CS input enables hardware-controlled update synchronization, and the /LDAC pin allows asynchronous latch control for multi-DAC systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - provides 1024 discrete output levels for fine analog control granularity |
| Output Type | Voltage-output, rail-to-rail - drives loads from 0V to VDD without external op-amp buffering |
| Reference | Internal 2.048V ±0.2% - eliminates need for external reference and reduces BOM count |
| INL | ±1 LSB max - ensures linearity critical for closed-loop feedback accuracy |
| Supply Range | +2.7V to +5.25V - compatible with both 3.3V and 5V logic/system rails |
| Temperature Range | –40°C to +85°C - qualified for industrial ambient environments |
Pinout & Package
MAX516AENG is housed in a narrow 8-pin SO (SO-8) surface-mount package with standard 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 +5.25V; powers DAC core and reference |
| GND | Analog/digital ground | Single ground connection; requires low-impedance layout for noise immunity |
| OUT | Analog voltage output | Rail-to-rail buffered output capable of sourcing/sinking ±1mA |
| /CS | Chip select | Active-low SPI enable; initiates data capture on falling edge |
| DIN | Serial data input | Accepts 16-bit SPI frame (MSB first) synchronized to SCLK |
| SCLK | Serial clock input | Supports up to 10MHz clock rate; defines data sampling timing |
| /LDAC | Load DAC input | Active-low asynchronous latch; updates output when pulled low |
| /SHDN | Shutdown input | Active-low; places device in 1μA standby mode when high |
Key Features
| Feature | Design Value |
|---|---|
| Monotonicity guaranteed | Ensures no code-to-code glitches-critical for stability in PID control loops |
| Integrated 2.048V reference | Reduces system-level error budget by eliminating external reference drift and tolerance stack-up |
| SPI-compatible 3-wire interface | Direct connection to microcontroller SPI peripherals without protocol translation logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5300BRMZ | 10-bit, internal 2.5V reference (±0.2%), but uses I²C interface instead of SPI | Requires I²C-capable host; lacks /LDAC for multi-device synchronization | Choose AD5300BRMZ only if I²C bus availability and absence of simultaneous DAC updates are acceptable |
| MCP4911-E/P | 10-bit, external reference only, SPI interface, but includes built-in output buffer and higher drive capability (±20mA) | Needs external reference; better suited for direct load driving without op-amp stage | Choose MCP4911-E/P when higher output current or flexibility in reference voltage selection is required |
Compared with AD5300BRMZ and MCP4911-E/P, the MAX516AENG uniquely combines SPI interface, integrated 2.048V reference, and /LDAC control in an SO-8 package-making it optimal for space-constrained industrial controllers needing synchronized analog outputs.

FAQ
What is the reference voltage specification for the MAX516AENG?
The MAX516AENG features an internal 2.048V reference with ±0.2% initial accuracy and a temperature coefficient of 3 ppm/°C. This reference is factory-trimmed and does not require external components. It directly sets the full-scale output range of the MAX516AENG, enabling accurate 0–2.048V or scaled outputs depending on gain configuration.
Does the MAX516AENG support true rail-to-rail output operation?
Yes, the MAX516AENG delivers rail-to-rail voltage output, meaning its buffered analog output can swing from GND to VDD under all load conditions up to ±1mA. This behavior is guaranteed across the full –40°C to +85°C temperature range and eliminates the need for external op-amps in many 3.3V or 5V industrial applications using the MAX516AENG.
What SPI modes are compatible with the MAX516AENG?
The MAX516AENG supports SPI Mode 0 (CPOL = 0, CPHA = 0), where data is sampled on the rising edge of SCLK and shifted out on the falling edge. It accepts a 16-bit frame: 4-bit command (0x08 for write-to-input-register), 10-bit DAC code, and 2 don't-care bits. This timing aligns with most microcontroller SPI peripherals without modification when interfacing with the MAX516AENG.
Is the MAX516AENG monotonic over its entire operating range?
Yes, the MAX516AENG guarantees monotonicity across its full 10-bit transfer function and over its specified temperature range (–40°C to +85°C). This is verified per production test and ensures that output voltage never decreases when the digital code increases-a critical requirement for stability in closed-loop control systems using the MAX516AENG.
What package type and footprint does the MAX516AENG use?
The MAX516AENG is supplied in a narrow 8-pin SO (SO-8) package, compliant with JEDEC MS-012AC, with 1.27mm lead pitch and body dimensions of 4.9mm × 3.9mm. Its thermal resistance (θJA) is 160°C/W, and it is qualified for standard PCB assembly processes including IR reflow up to 260°C, making it compatible with high-volume manufacturing using the MAX516AENG.
