Product details
Overview
MAX516BCNG from Maxim Integrated is a 10-bit, single-channel, voltage-output DAC with internal reference, rail-to-rail output, and 16-pin DIP package; features ±1 LSB INL/DNL, 10 µs settling time, and operates from +4.5V to +5.5V supply; used in industrial process control loop calibration.
For engineers reviewing the MAX516BCNG datasheet, MAX516BCNG pinout, MAX516BCNG application, or MAX516BCNG equivalent, key selection considerations include output drive capability, reference stability over temperature, monotonicity assurance, and compatibility with legacy 16-pin through-hole control systems.
Technical Context
The MAX516BCNG implements a R-2R ladder architecture with buffered voltage output, supporting unipolar 0V to VREF operation. It integrates a precision 2.56V bandgap reference with ±0.5% initial accuracy and 25 ppm/°C drift.
Control interface is parallel 10-bit TTL/CMOS-compatible, requiring no external clock or serial protocol overhead. Latch enable (LE) and write (WR) signals provide asynchronous data capture timing aligned with host microcontroller bus cycles.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-output DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7524JRZ | 8-bit resolution, external reference required, no internal buffer, 20 µs settling | Suitable for lower-precision, cost-sensitive industrial controls where 10-bit resolution not mandated | Select AD7524JRZ only when BOM cost reduction outweighs resolution and settling time requirements |
| MAX517ACPA+ | I²C interface, 8-bit, SO-8 package, no internal reference, 4.5V–5.5V supply | Fits space-constrained designs needing serial control but lacking parallel bus resources | Choose MAX517ACPA+ only if board layout allows SO-8 footprint and firmware supports I²C protocol stack |
Compared with AD7524JRZ and MAX517ACPA+, the MAX516BCNG provides higher resolution, faster settling, and integrated reference-making it optimal for retrofitting legacy parallel-bus systems requiring precision and drop-in mechanical compatibility.

FAQ
What is the reference voltage specification for the MAX516BCNG?
The MAX516BCNG integrates a precision 2.56V bandgap reference with ±0.5% initial accuracy and a temperature coefficient of 25 ppm/°C. This internal reference is accessible at the VREF pin and serves as the full-scale output reference for the DAC. The MAX516BCNG does not require an external reference unless overridden for custom scaling.
Is the MAX516BCNG pin-compatible with other Maxim DACs in 16-pin DIP packages?
No-the MAX516BCNG has a unique pinout optimized for its parallel interface and internal reference architecture. While other Maxim DIP DACs like the MAX515 share the same package outline, their pin assignments for WR, LE, and VREF differ. Always verify pin mapping against the MAX516BCNG datasheet before substitution.
Does the MAX516BCNG support bipolar output operation?
No-the MAX516BCNG is specified for unipolar operation only (0V to VREF). Its rail-to-rail output stage cannot swing below ground or above VREF without external op-amp circuitry. For bipolar applications, external summing amplifiers or dual-supply DACs such as the MAX538 must be used instead of the MAX516BCNG.
What is the maximum update rate achievable with the MAX516BCNG?
The MAX516BCNG achieves a 10 µs settling time to ±1/2 LSB, enabling a theoretical maximum update rate of 100 kSPS under ideal timing conditions. Real-world throughput depends on host processor bus speed and WR/LE signal timing margins; typical implementations achieve 50–80 kSPS in 8051-based systems using the MAX516BCNG.
Can the MAX516BCNG operate from a +3.3V supply?
No-the MAX516BCNG requires a +4.5V to +5.5V supply and is not rated for +3.3V operation. Attempting to power the MAX516BCNG from +3.3V will result in undefined behavior, including failure to latch data or produce valid output. Systems using +3.3V logic must implement level translation or select a 3.3V-compatible DAC such as the MAX5302 instead of the MAX516BCNG.
