Product details
Overview
MAX516BCNG+ from Maxim Integrated is a 12-bit, single-channel voltage-output DAC with internal reference, rail-to-rail output, and 16-pin DIP package. It operates from a +5V supply, delivers ±1 LSB integral nonlinearity, and supports unipolar 0V to +4.096V output range. It is used in precision industrial control loop calibration and analog front-end trimming.
For engineers reviewing the MAX516BCNG+ datasheet, MAX516BCNG+ pinout, MAX516BCNG+ application, or MAX516BCNG+ equivalent, key selection criteria include its internal 4.096V reference accuracy (±0.2%), 12-bit monotonicity, and compatibility with microcontroller SPI-compatible serial interface timing.
Technical Context
The MAX516BCNG+ implements a resistor-string architecture with buffered voltage output, eliminating external op-amp requirements for basic applications. Its serial interface uses a 3-wire protocol (CS, SCLK, DIN) with 16-bit frame length including 4-bit command and 12-bit data.
It features power-on reset that forces output to zero volts and includes a shutdown mode reducing supply current to 2µA. The device is specified over 0°C to +70°C ambient temperature range and maintains 12-bit linearity without calibration.

Pinout & Package
MAX516BCNG+ is housed in a 16-pin plastic DIP (Dual In-line Package) with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch, compatible with standard PCB prototyping and production tooling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply | Accepts +5V input; powers internal reference and output buffer |

| DIN | Serial data input | Accepts 16-bit command/data stream MSB-first on SCLK rising edge |
| SCLK | Serial clock | Drives data sampling; max rate 2MHz supports fast update cycles |
| OUT | Analog output | Rail-to-rail buffered voltage output; drives ≥2kΩ load with <0.1% gain error |
| SHDN | Shutdown control | Active-low; reduces current to 2µA and sets OUT to high-impedance state |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-output DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD558KNZ | 8-bit resolution, internal +10V reference, 16-pin DIP, no shutdown mode | Limited to lower-accuracy trimming where 0.4% FS error is acceptable | Select when cost sensitivity outweighs resolution and power-saving needs |
| MCP4921-E/P | 12-bit, SPI interface, external reference required, 8-pin PDIP, no internal reference | Requires external 4.096V reference and decoupling; adds BOM and layout complexity | Select when board space is constrained and reference flexibility is prioritized |
Compared with AD558KNZ and MCP4921-E/P, the MAX516BCNG+ uniquely integrates precision reference and shutdown in a drop-in 16-pin DIP footprint-reducing component count and enabling zero-volt power-on safety without redesign.

FAQ
What is the absolute maximum supply voltage for the MAX516BCNG+?
The MAX516BCNG+ has an absolute maximum supply voltage of +7V. Operation above +5.25V or below +4.75V may degrade reference accuracy and increase INL beyond ±1 LSB. For reliable long-term performance in industrial environments, maintain VDD within ±5% of +5V as specified in the MAX516BCNG+ datasheet.
Does the MAX516BCNG+ require an external reference?
No, the MAX516BCNG+ does not require an external reference. It integrates a precision 4.096V bandgap reference with ±0.2% initial accuracy and low temperature drift. This eliminates external reference components and associated PCB area, making the MAX516BCNG+ a self-contained solution for unipolar 0V–4.096V output applications.
What is the output settling time of the MAX516BCNG+?
The MAX516BCNG+ achieves full-scale settling to ±1/2 LSB in 10µs. This specification applies under load conditions of 2kΩ || 100pF and with VDD = +5V. The fast settling supports dynamic calibration sequences in automated test equipment and real-time control loop updates where the MAX516BCNG+ serves as the final analog actuator.
Can the MAX516BCNG+ operate in bipolar output mode?
No, the MAX516BCNG+ is configured exclusively for unipolar output (0V to +4.096V). It lacks internal circuitry for negative voltage generation or level-shifting. To achieve bipolar operation, external op-amp circuitry with dual supplies must be added-however, doing so voids the guaranteed ±1 LSB INL and rail-to-rail performance of the MAX516BCNG+ alone.
Is the MAX516BCNG+ pin-compatible with other Maxim DACs in 16-pin DIP?
No, the MAX516BCNG+ is not pin-compatible with other Maxim 16-pin DIP DACs such as the MAX538 or MAX541. Its CS, DIN, and SCLK pin assignments differ, and it lacks pins for external reference input or asynchronous clear. Board-level replacement requires schematic and layout revision; the MAX516BCNG+ must be designed in from the outset.
