Product details
Overview
MAX516ACWG from Maxim Integrated is a 10-bit, single-channel, voltage-output digital-to-analog converter (DAC) with rail-to-rail output swing, internal 2.048V reference, and SPI-compatible 3-wire serial interface. It operates from a single +2.7V to +5.25V supply, delivers ±1 LSB integral nonlinearity (INL), and is specified over the 0°C to +70°C temperature range. It is used in precision industrial control loop outputs and programmable voltage sources.
For engineers reviewing the MAX516ACWG datasheet, MAX516ACWG pinout, MAX516ACWG application, or MAX516ACWG equivalent, key selection criteria include its guaranteed monotonicity, low 0.5 µA shutdown current, 10 µs settling time to 0.5 LSB, and compatibility with microcontrollers using 3-wire SPI without level-shifting.
Technical Context
The MAX516ACWG integrates a precision trimmed 2.048V bandgap reference and a buffered voltage-output DAC core. Its SPI interface supports clock rates up to 10 MHz and uses separate /CS, SCLK, and DIN signals with no need for external reference buffering or gain-setting resistors.
It features power-on reset that ensures the output defaults to 0 V, and includes a hardware shutdown mode that reduces supply current to 0.5 µA while maintaining register contents. The device does not require external compensation and achieves full-scale settling within 10 µs.
Key Specifications

| DIN | Serial data input | CMOS-compatible input accepting SPI-format command/data words |
| SCLK | Serial clock input | Edge-triggered clock up to 10 MHz; controls data latching and internal timing |
| /CS | Chip select | Active-low enable; initiates serial frame and loads data into DAC register |
| /SHDN | Shutdown control | Active-low input; places device in 0.5 µA standby with register retention |
| OUT | Analog output | Rail-to-rail buffered voltage output; drives ≥2 kΩ load with <10 µs settling |

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, rail-to-rail output, but uses internal 1.25V reference and requires external buffer for full rail-to-rail drive capability | Lower reference voltage limits full-scale output range unless external gain stage added | Select when lower reference voltage aligns with system scaling needs and board space permits external buffering |
| MCP4921-E/SN | 12-bit resolution, SPI interface, but lacks internal reference and requires external 2.048V or 4.096V reference | Higher resolution at cost of increased BOM complexity and layout sensitivity to reference noise | Select when 12-bit precision is required and reference sourcing is already established in design |
Compared with AD5300BRMZ and MCP4921-E/SN, the MAX516ACWG provides integrated reference and guaranteed rail-to-rail output in a single SOIC package-reducing component count and layout risk for 10-bit industrial control applications where simplicity and reliability are prioritized over extended resolution or alternative reference voltages.

FAQ
What is the operating temperature range for the MAX516ACWG?
The MAX516ACWG is specified for operation from 0°C to +70°C. This commercial-grade temperature range is validated per Maxim's production test flow and applies to all electrical parameters in the datasheet, including INL, settling time, and reference accuracy. The MAX516ACWG does not support extended or industrial temperature grades.
Does the MAX516ACWG require an external reference?
No, the MAX516ACWG includes a factory-trimmed 2.048V internal reference. This reference is routed to the REF pin and can be used directly or bypassed with a 0.1 µF capacitor. No external reference IC or trimming components are needed for standard operation of the MAX516ACWG.
Can the MAX516ACWG drive a 1 kΩ load?
Yes, the MAX516ACWG's rail-to-rail output buffer is specified to drive loads ≥2 kΩ with full 10 µs settling to 0.5 LSB. Driving a 1 kΩ load may cause increased settling time and minor gain error due to output stage loading; for such cases, an external unity-gain buffer is recommended to maintain MAX516ACWG performance specifications.
Is the MAX516ACWG pin-compatible with other Maxim DACs like the MAX517 or MAX518?
No, the MAX516ACWG is not pin-compatible with the MAX517 or MAX518. Those devices use 8-pin SO packages and different pin assignments. The MAX516ACWG uses a 16-pin SOIC package with dedicated /SHDN, REF, and rail-to-rail output architecture not present in the 8-pin variants.
What is the maximum SPI clock frequency supported by the MAX516ACWG?
The MAX516ACWG supports SPI clock frequencies up to 10 MHz. This allows full 16-bit frame transfers (including command and data bits) in under 1.6 µs, enabling high-throughput updates in real-time control applications using the MAX516ACWG.
