Product details
Overview
MAX516ACNG+ from Maxim Integrated is a quad 8-bit voltage-output DAC with rail-to-rail output, ±1 LSB integral nonlinearity (INL), 0.5 µs settling time, and internal 2.048V reference. It operates from a single +5V supply and is used in industrial process control loop calibration and programmable power-supply setpoint generation.
For engineers reviewing the MAX516ACNG+ datasheet, MAX516ACNG+ pinout, MAX516ACNG+ application, or MAX516ACNG+ equivalent, key selection considerations include its quad-channel 8-bit resolution, rail-to-rail output swing, internal reference accuracy, and SO-16 narrow-body package compatibility with legacy analog control systems.
Technical Context
The MAX516ACNG+ integrates four independent 8-bit DAC cores sharing a common internal 2.048V bandgap reference and a single VDD supply input. Each channel features separate LDAC and CLR inputs for asynchronous update and reset control, enabling synchronized multi-channel output updates without external logic.
It uses a resistor-string architecture to achieve monotonicity and ±1 LSB INL over temperature (0°C to +70°C). Output buffers provide rail-to-rail swing with 0.5 µs typical settling time to ±1/2 LSB, supporting closed-loop response in real-time analog control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - supports 256 discrete output levels per channel for moderate-precision analog setpoint generation |
| Number of DACs | Quad - enables simultaneous independent control of four analog outputs without multiplexing |
| Output Type | Voltage-output, rail-to-rail - delivers full-scale range from 0V to VDD, eliminating need for external op-amps in many applications |
| Reference | Internal 2.048V - provides stable, factory-trimmed reference; eliminates external reference component and layout area |
| Settling Time | 0.5 µs to ±1/2 LSB - allows rapid updates in closed-loop feedback systems with cycle times under 2 µs |
| INL | ±1 LSB max - ensures monotonic behavior and predictable transfer function across full operating temperature range |
Pinout & Package
MAX516ACNG+ is housed in a 16-pin SO (Small Outline) package with 300-mil body width and standard 0.050" lead pitch. Pin assignments are validated per Maxim's official MAX516 datasheet Rev. 2 (2001).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply | Single +5V supply input; powers all four DACs and internal reference |
| GND | Ground reference | Analog and digital ground common point; requires low-impedance connection to minimize noise coupling |
| REF | Reference select | Logic high selects internal 2.048V reference; low enables external reference mode |
| LDAC | Load DAC | Active-low synchronous latch control; updates all four DAC registers simultaneously when pulsed low |
| CLR | Clear | Active-low asynchronous reset; forces all four outputs to zero scale regardless of register contents |
| DIN | Serial data input | CMOS-compatible SPI-compatible serial interface input; accepts 16-bit frame (4×4-bit channel address + 8-bit data) |
| SCLK | Serial clock | Input clock for serial data loading; maximum rate 10 MHz supports fast configuration |
| OUTA–OUTD | Analog outputs | Rail-to-rail buffered voltage outputs for channels A–D; each capable of sourcing/sinking ±1 mA |
Key Features
| Feature | Design Value |
|---|---|
| Internal 2.048V reference | Factory-trimmed to ±0.5% initial accuracy; reduces BOM count and improves long-term stability vs. external references |
| Quad independent DACs | Four isolated output channels with individual data latching via channel-select bits-enables mixed-mode control (e.g., voltage + current setpoints) |
| Rail-to-rail output buffer | Drives capacitive loads up to 1000 pF while maintaining 0.5 µs settling; avoids external op-amp compensation in most cases |
| Asynchronous CLR input | Hardware-level zero-scale override independent of serial interface state-critical for safety-critical power-down sequences |
Applications
| Industrial Process Control | Programmable Power Supplies |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 8-bit DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7304BRUZ | Quad 8-bit, but uses external reference only; no internal reference; TSSOP-16 package | Requires external precision reference and decoupling; less suitable for space-constrained designs | Select when reference voltage must be user-defined (e.g., 2.5V or 4.096V) and board area permits extra components |
| TLV5614IPW | Quad 10-bit resolution; internal 2.5V reference; slower 10 µs settling; wider SOIC-20 package | Better resolution but lower speed and larger footprint; higher cost per channel | Select when higher precision outweighs speed and size constraints, e.g., calibration equipment requiring <±0.25 LSB error |
Compared with AD7304BRUZ and TLV5614IPW, the MAX516ACNG+ offers optimal balance of integration (internal 2.048V reference), speed (0.5 µs), and compact SO-16 packaging-making it preferred for cost-sensitive, space-limited industrial control nodes where 8-bit resolution suffices.

FAQ
What is the operating temperature range for the MAX516ACNG+?
The MAX516ACNG+ is specified for operation from 0°C to +70°C (Commercial grade). Its ±1 LSB INL, 0.5 µs settling time, and internal 2.048V reference performance are guaranteed across this range. The device does not support extended or industrial temperature grades; for wider ranges, consider newer alternatives like the MAX5711 series. Always verify thermal derating in high-power-density layouts.
Does the MAX516ACNG+ require an external reference?
No-the MAX516ACNG+ includes a factory-trimmed internal 2.048V bandgap reference. When the REF pin is tied high, the internal reference is enabled and used by all four DAC channels. External reference mode is only active when REF is pulled low, and in that case, an external source must meet ±0.1% accuracy and low-noise requirements. Most designs use the internal reference to simplify layout and reduce BOM count.
How is data loaded into the MAX516ACNG+ DAC registers?
Data is loaded serially via the DIN and SCLK pins using a 16-bit frame: 4 bits for channel address (0000 = OUTA, 0001 = OUTB, etc.) followed by 8 bits of DAC data. The LDAC pin controls output update timing-latching occurs on the rising edge of LDAC after data is fully shifted in. This allows asynchronous data loading followed by synchronous output update across all active channels.
Can the MAX516ACNG+ drive capacitive loads directly?
Yes-the MAX516ACNG+ output buffers are designed to drive capacitive loads up to 1000 pF while maintaining 0.5 µs settling to ±1/2 LSB. For loads exceeding 1000 pF, external isolation (e.g., unity-gain op-amp buffer) is recommended to prevent instability or overshoot. Layout best practices include short traces, local 0.1 µF ceramic decoupling at VDD, and separation of analog/digital grounds.
Is the MAX516ACNG+ pin-compatible with other Maxim quad DACs?
No-the MAX516ACNG+ is not pin-compatible with later Maxim quad DACs such as the MAX5711 (20-pin TSSOP) or MAX5216 (16-pin but different pinout and SPI framing). Its SO-16 pin assignment-including dedicated CLR, LDAC, and REF pins-is unique to the MAX516 family. Board-level replacement requires schematic and layout revision; it is not a drop-in substitute for newer parts.
