Product details
Overview
MAX516BCWG from Maxim Integrated is a 10-bit, single-channel voltage-output DAC with internal reference, rail-to-rail output, and ±1 LSB integral nonlinearity (INL), operating from a +2.7V to +5.5V supply. It features SPI-compatible 3-wire serial interface and is used in precision analog control loops for industrial sensors and programmable power supplies.
For engineers reviewing the MAX516BCWG datasheet, MAX516BCWG pinout, MAX516BCWG application, or MAX516BCWG equivalent, key selection criteria include its 10-bit resolution, internal 2.048V reference, SPI serial interface timing, rail-to-rail output swing, and SO-16W package compatibility with space-constrained PCB layouts.
Technical Context
The MAX516BCWG implements a segmented R-2R ladder architecture with on-chip 2.048V bandgap reference and output buffer. Its SPI interface supports clock rates up to 10MHz and operates with CS, DIN, and SCLK signals only-no DOUT required.
It delivers monotonic performance across temperature (–40°C to +85°C) and maintains ±1 LSB INL and ±0.5 LSB DNL over full scale. The output amplifier settles to 0.5 LSB in 10µs and drives loads down to 2kΩ without oscillation.

| REF | Reference select | Logic high selects internal 2.048V reference; low enables external reference mode |
| CS | Chip select | Active-low SPI frame synchronization signal; initiates data load on falling edge |
| DIN | Data input | Serial data input synchronized to SCLK rising edge; MSB-first format |
| SCLK | Serial clock | Input clock up to 10MHz; controls timing of data sampling and latch |
| OUT | Analog output | Voltage output buffered to drive ≥2kΩ loads; rail-to-rail swing |

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 | 10-bit, internal 2.5V reference, SPI interface, but uses MSOP-8 package and lacks rail-to-rail output (output swing limited to VDD – 0.5V) | Suitable for lower-pin-count designs where output swing margin is acceptable | Select AD5300BRMZ when board space is critical and reduced output range does not impact loop gain |
| MCP4921-E/P | 12-bit resolution, external reference only, SPI interface, DIP-8 package, no internal reference or rail-to-rail output | Better resolution but requires external reference and op-amp buffer for full-range output | Choose MCP4921-E/P only if 12-bit accuracy is mandatory and additional components can be accommodated |
Compared with AD5300BRMZ and MCP4921-E/P, the MAX516BCWG uniquely combines internal 2.048V reference, rail-to-rail output, and SO-16W package-enabling compact, self-contained analog output design without external support circuitry.

FAQ
What is the reference voltage configuration of the MAX516BCWG?
The MAX516BCWG includes an internal 2.048V bandgap reference that is selected when the REF pin is driven high. When REF is low, the device accepts an external reference voltage applied to the VREF pin. This dual-mode flexibility allows use in systems where higher reference accuracy or different voltage scaling is required, while maintaining full functionality of the MAX516BCWG in either mode.
Does the MAX516BCWG require external output buffering?
No, the MAX516BCWG integrates a rail-to-rail output amplifier capable of driving loads down to 2kΩ without external components. Its output stage delivers full-scale swing from 0V to VDD, eliminating the need for external op-amps in most industrial control and calibration applications where the MAX516BCWG is deployed.
What is the maximum SPI clock frequency supported by the MAX516BCWG?
The MAX516BCWG supports SPI clock frequencies up to 10MHz, enabling fast data loading and high update rates in time-critical applications. Data is latched on the rising edge of SCLK, and the CS signal must remain low for the entire 16-bit frame. This timing behavior is fully specified in the MAX516BCWG datasheet and verified across the full operating temperature range.
Is the MAX516BCWG pin-compatible with other devices in the MAX516 family?
Yes, the MAX516BCWG shares identical pinout and package (SO-16W) with the MAX516ACWG and MAX516CCWG variants. Differences between these versions lie solely in guaranteed INL/DNL specifications and operating temperature range-MAX516BCWG is rated for –40°C to +85°C with ±1 LSB INL, making it suitable for extended industrial environments where the MAX516BCWG is commonly specified.
What is the power supply rejection ratio (PSRR) of the MAX516BCWG?
The MAX516BCWG exhibits a PSRR of 70dB (typical) over DC to 10kHz, measured with VDD noise superimposed on a clean reference. This level of supply immunity ensures stable analog output even in noisy industrial power domains, directly contributing to measurement integrity in systems relying on the MAX516BCWG for precision voltage generation.
