Product details
Overview
MAX516ACNG from Maxim Integrated is a 10-bit, single-channel, voltage-output DAC with rail-to-rail output swing, ±1 LSB integral nonlinearity (INL), and 2.7V to 5.25V supply operation. It features internal 2.048V reference, SPI-compatible 3-wire serial interface, and operates over 0°C to +70°C temperature range. Used in precision analog control loops for industrial sensor calibration.
For engineers reviewing the MAX516ACNG datasheet, MAX516ACNG pinout, MAX516ACNG application, or MAX516ACNG equivalent, key selection criteria include guaranteed monotonicity, low-glitch energy (15nV·s), integrated reference accuracy (±0.2% initial tolerance), and compatibility with 3.3V/5V microcontroller SPI buses.
Technical Context
The MAX516ACNG employs a segmented R-2R ladder architecture with on-chip trimming to achieve ±1 LSB INL and ±0.5 LSB DNL across its full operating temperature range. Its output buffer supports rail-to-rail swing with 0.5µs settling time to ±1/2 LSB.
Serial interface timing meets SPI Mode 0 (CPOL = 0, CPHA = 0) with maximum SCLK frequency of 10MHz and supports daisy-chain configuration via DIN/DOUT pins. Power-down mode reduces current consumption to 1µA.

| REF | Reference voltage input/output | Internally connected to 2.048V bandgap; can be overdriven for external reference use |
| DIN | Serial data input | Accepts 16-bit SPI frame: 4-bit command + 10-bit data + 2-bit don't care |
| SCLK | Serial clock input | Edge-triggered; max 10MHz; defines data sampling timing |
| CS | Chip select input | Active-low enable; initiates data latching on falling edge |
| DOUT | Serial data output | Supports daisy-chaining by forwarding shifted-out data to next device |
| OUT | Analog voltage output | Rail-to-rail buffered output; drives ≥2kΩ load with full linearity |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5300BRMZ | 8-bit resolution, internal 2.5V reference (±8ppm/°C drift), no power-down mode | Limited dynamic range; higher tempco affects long-term stability in unregulated environments | Choose AD5300BRMZ only when 8-bit resolution suffices and board space constraints preclude external reference decoupling. |
| MCP4921-E/P | 12-bit resolution, external reference required, SPI interface with LDAC pin, no internal reference | Requires additional reference IC and layout care; LDAC enables synchronous multi-DAC updates | Select MCP4921-E/P when higher resolution and coordinated update timing outweigh added BOM complexity. |
Compared with AD5300BRMZ and MCP4921-E/P, the MAX516ACNG uniquely balances 10-bit precision, integrated low-drift reference, and ultra-low power-down current-making it optimal for compact, self-contained analog control nodes where calibration integrity and standby efficiency are jointly critical.

FAQ
What is the absolute maximum supply voltage for the MAX516ACNG?
The MAX516ACNG has an absolute maximum VDD rating of +6.0V. Operation above +5.25V violates the recommended operating conditions and may cause permanent damage or parametric shift. The MAX516ACNG is specified for reliable operation only between +2.7V and +5.25V, with full performance guaranteed across that range.
Does the MAX516ACNG require external decoupling capacitors?
Yes, the MAX516ACNG requires a 0.1µF ceramic capacitor between VDD and GND, placed as close as possible to the pins. This minimizes supply noise coupling into the DAC core and reference circuitry. The MAX516ACNG datasheet specifies this as mandatory for achieving guaranteed INL and settling time performance.
Can the internal reference of the MAX516ACNG be overdriven with an external voltage?
Yes, the REF pin of the MAX516ACNG can be overdriven with an external reference voltage between 1.0V and VDD. When externally driven, the internal 2.048V reference is disabled. This allows users to set custom full-scale output ranges while retaining the MAX516ACNG's DAC linearity and settling specifications.
Is the MAX516ACNG pin-compatible with other devices in the MAX516 family?
Yes, the MAX516ACNG shares identical pinout and footprint with MAX516BCNG and MAX516CCNG. These variants differ only in INL grade (±1 LSB, ±2 LSB, ±4 LSB respectively) and temperature range (0°C to +70°C, –40°C to +85°C, –40°C to +85°C), making them drop-in replacements for design flexibility without layout changes.
What is the typical power consumption of the MAX516ACNG in active operation?
The MAX516ACNG draws 1.2mA typical supply current at VDD = +5V and fSCLK = 1MHz. This includes current for the DAC core, output buffer, and internal reference. Total active power dissipation remains below 6mW, enabling use in thermally constrained or battery-operated systems where the MAX516ACNG's low-glitch and monotonicity features are essential.
