Product details
Overview
MAX516ACWG+T from Maxim Integrated is a 10-bit, single-channel voltage-output DAC with rail-to-rail output swing, ±1 LSB integral nonlinearity (INL), and 2.7V to 5.5V supply operation. It features internal 2.048V reference, SPI-compatible 3-wire serial interface, and operates over 0°C to +70°C temperature range for industrial sensor signal conditioning.
For engineers reviewing the MAX516ACWG+T datasheet, MAX516ACWG+T pinout, MAX516ACWG+T application, or MAX516ACWG+T equivalent, key selection criteria include output voltage range, reference integration, serial interface compatibility, INL performance, and operating temperature grade.
Technical Context
The MAX516ACWG+T uses a resistor-string architecture with buffered voltage output, enabling monotonicity and low glitch energy. Its SPI-compatible serial interface supports clock rates up to 10MHz and includes independent LDAC and CLR inputs for synchronous update and output reset.
Internal 2.048V reference provides fixed full-scale output of 0–2.048V (unbuffered) or 0–4.096V (with external gain), while the rail-to-rail output amplifier delivers ±1 LSB INL and ±0.5 LSB DNL across the full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - supports 1024 discrete output levels for precision analog control |
| INL | ±1 LSB - ensures accurate transfer function without calibration in closed-loop systems |
| Reference | Internal 2.048V - eliminates need for external reference component and reduces BOM count |
| Interface | SPI-compatible 3-wire - enables direct connection to microcontrollers with standard SPI peripherals |
| Supply Range | 2.7V to 5.5V - compatible with both 3.3V and 5V logic/system domains |
| Output Type | Rail-to-rail voltage - delivers full dynamic range across supply rails for maximum signal utilization |
Pinout & Package
MAX516ACWG+T is housed in a 16-pin SOIC package (width 0.295", 7.5mm) with exposed pad for thermal enhancement and standard JEDEC MO-153 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply | Accepts 2.7V–5.5V; powers internal DAC core and reference |
| GND | Ground reference | Common return for analog and digital sections; requires low-impedance connection |
| VOUT | Analog output | Rail-to-rail buffered voltage output; drives loads ≥2kΩ |
| REF | Reference input/output | Internally connected to 2.048V bandgap; can be overdriven or bypassed externally |
| DIN | Serial data input | CMOS-compatible; accepts SPI-format 16-bit frame (start bit + 10-bit code + 6-bit command) |
| SCLK | Serial clock | Edge-triggered; supports up to 10MHz clock for <1μs update latency |
| LDAC | Load DAC | Active-low asynchronous latch; updates VOUT on falling edge when not in power-down |
| CLR | Clear output | Active-low; forces VOUT to 0V regardless of loaded code |
Key Features
| Feature | Design Value |
|---|---|
| Internal 2.048V reference | Reduces system component count and layout area; eliminates external reference trimming |
| Rail-to-rail output amplifier | Delivers full-scale output from 0V to VDD, maximizing usable dynamic range in single-supply systems |
| ±1 LSB INL (max) | Enables uncalibrated accuracy in process control loops and sensor offset correction |

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 | 8-bit resolution, internal 2.5V reference, same SOIC-16 package | Limited to lower-precision biasing where ±4 LSB INL is acceptable | Choose AD5300BRMZ-REEL7 for cost-sensitive, lower-accuracy sensor trimming where 10-bit resolution is unnecessary |
| MCP4921-E/SN | 12-bit resolution, external reference only, SPI interface, SOIC-8 package | Requires external reference and level-shifting for 5V systems; smaller footprint but no internal reference | Choose MCP4921-E/SN when higher resolution is required and board space is constrained, accepting added BOM and layout effort |
Compared with AD5300BRMZ-REEL7 and MCP4921-E/SN, the MAX516ACWG+T uniquely balances 10-bit accuracy, integrated reference, rail-to-rail output, and industry-standard SOIC-16 packaging-making it optimal for industrial analog output modules requiring calibrated, single-supply operation without reference design overhead.

FAQ
What is the absolute maximum supply voltage for the MAX516ACWG+T?
The MAX516ACWG+T has an absolute maximum supply voltage rating of 6.0V on VDD. Operation above 5.5V violates the recommended operating conditions and may cause permanent damage or parametric shift. For reliable long-term use, maintain VDD between 2.7V and 5.5V as specified in the MAX516ACWG+T datasheet.
Does the MAX516ACWG+T require an external reference to operate?
No, the MAX516ACWG+T does not require an external reference. It integrates a factory-trimmed 2.048V bandgap reference connected to the REF pin. This internal reference enables full functionality-including specified INL and output accuracy-without any external components, simplifying design and reducing BOM cost.
Can the MAX516ACWG+T drive capacitive loads directly?
The MAX516ACWG+T output amplifier is specified to drive resistive loads ≥2kΩ. Driving capacitive loads >100pF may cause instability or overshoot. For capacitive loads, use an external unity-gain buffer op-amp. The MAX516ACWG+T datasheet does not guarantee stability or settling time with direct capacitive loading.
What is the purpose of the LDAC pin on the MAX516ACWG+T?
The LDAC (Load DAC) pin on the MAX516ACWG+T is an active-low asynchronous control that latches the DAC register contents to the output stage. When pulled low, it updates VOUT immediately-even if new data is being shifted in-enabling synchronized multi-DAC updates in systems with multiple MAX516ACWG+T devices.
Is the MAX516ACWG+T RoHS-compliant and lead-free?
Yes, the MAX516ACWG+T is RoHS-compliant and lead-free. The "+T" suffix denotes tape-and-reel packaging and confirms compliance with EU RoHS Directive 2011/65/EU and JEDEC JS-066 standards. The device uses matte tin lead finish and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3 requirements.
