Product details
Overview
MAX516BCWG+ from Maxim Integrated is a 10-bit, single-channel voltage-output DAC with rail-to-rail output swing, ±1 LSB integral nonlinearity (INL), and 1 µs settling time. It operates from a +2.7V to +5.5V supply and features internal 2.048V reference, making it suitable for precision analog control in industrial sensor interfaces.
For engineers reviewing the MAX516BCWG+ datasheet, MAX516BCWG+ pinout, MAX516BCWG+ application, or MAX516BCWG+ equivalent, key selection considerations include its guaranteed monotonicity over temperature, SPI-compatible 3-wire serial interface, and operation without external reference components.
Technical Context
The MAX516BCWG+ integrates a precision 10-bit R-2R ladder DAC core with an internal 2.048V bandgap reference and rail-to-rail output buffer. It accepts serial data via SPI-compatible 3-wire interface (DIN, SCLK, CS) and supports power-down mode consuming only 1 µA typical.
Its architecture delivers guaranteed monotonicity across –40°C to +85°C, ±1 LSB differential nonlinearity (DNL), and 0.5 LSB offset error. The output amplifier drives loads down to 2 kΩ while maintaining full-scale accuracy.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-output DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5300BRMZ-REEL7 | 10-bit, internal 2.5V reference, 10 µs settling time, SPI interface | Larger settling time limits use in high-speed waveform generation | Preferred where higher reference voltage (2.5V) and AEC-Q200 qualification are required |

FAQ
What is the reference voltage configuration of the MAX516BCWG+?
The MAX516BCWG+ features a selectable reference configuration: when the REF pin is high, the device uses its internal 2.048V ±0.5% bandgap reference; when REF is low, it accepts an external reference applied to the VREF pin. This dual-mode design allows flexibility between self-contained operation and higher-accuracy external references. The MAX516BCWG+ maintains full specification compliance in both modes.
Does the MAX516BCWG+ require external components for basic operation?
No, the MAX516BCWG+ operates fully functional with only VDD, GND, and digital interface connections. Its internal 2.048V reference, rail-to-rail output buffer, and power-down circuitry eliminate the need for external op-amps, reference ICs, or decoupling beyond standard 0.1 µF ceramic capacitors. This reduces BOM count and PCB area-key advantages confirmed in the MAX516BCWG+ datasheet and evaluation board schematics.
What is the maximum SPI clock frequency supported by the MAX516BCWG+?
The MAX516BCWG+ supports a maximum SCLK frequency of 10 MHz, enabling full 16-bit frame transfers in under 1.6 µs. This timing aligns with standard microcontroller SPI peripherals and ensures reliable communication even at high update rates. The MAX516BCWG+ datasheet specifies setup/hold timing margins that remain valid up to this limit across the full operating temperature range.
Is the MAX516BCWG+ pin-compatible with other devices in the MAX516 family?
Yes, all variants in the MAX516 family-including MAX516ACWG+, MAX516BCWG+, and MAX516CCWG+-share identical 16-pin SOIC pinouts and electrical interfaces. The only differences are grade-specific performance parameters: MAX516BCWG+ guarantees ±1 LSB INL over –40°C to +85°C, while 'A' and 'C' grades specify tighter or looser tolerances. Hardware design using MAX516BCWG+ remains unchanged across these variants.
How does the power-down mode affect register retention in the MAX516BCWG+?
In power-down mode (PD pin high), the MAX516BCWG+ reduces supply current to 1 µA typical while retaining the last-loaded DAC code in its internal register. Upon exit from power-down, the output resumes at the previously set voltage without requiring reinitialization. This behavior is explicitly characterized in the MAX516BCWG+ datasheet and verified in application notes for battery-powered systems.
