- **Package:** 16-TSSOP  

### **Descriptions:**
The MAX5291BEUE is a single-channel, 12-bit voltage-output DAC with a serial interface. It operates from a single supply voltage (2.7V to 5.5V) and provides a rail-to-rail output buffer. The device is compatible with SPI/QSPI/MICROWIRE interfaces, making it suitable for microcontroller-based applications.  

### **Features:**
- **Low Power Consumption:** 0.4mA (typ) at 3V  
- **Rail-to-Rail Output Buffer**  
- **Power-On Reset to Zero Scale or Midscale (Software Selectable)**  
- **SPI/QSPI/MICROWIRE-Compatible Serial Interface**  
- **16-Pin TSSOP Package**  
- **External Voltage Reference Input**  
- **Low Glitch Energy (1nV-s typ)**  

This DAC is designed for precision industrial control, automated test equipment, and other applications requiring high-accuracy analog outputs.

Application Scenarios & Design Considerations

Buffered, Fast-Settling, Dual, 12-/10-/8-Bit, Voltage-Output DACs

Alternative Part Number

  • AD5662BRMZ-1 --: Single-channel 16-bit DAC with similar SPI interface and voltage output, pin-compatible in many designs and widely available.
  • DAC8551IDGK --: 16-bit single-channel DAC with SPI interface, comparable accuracy and small package, suitable drop-in replacement with minor layout review.
  • MCP4921-E/SN --: 12-bit SPI DAC offering lower resolution but similar function and supply range, good cost-effective alternative when 16-bit precision is not critical.
  • AD5662BRMZ --: Single-channel 16-bit DAC with similar SPI interface and voltage output, pin-compatible in many designs and widely available.
  • DAC8552IDGKR --: Dual-channel 16-bit DAC with SPI interface, comparable resolution and performance, suitable drop-in replacement with minor layout adjustment.
  • MCP4822-E/MS --: Dual 12-bit DAC with SPI interface, lower resolution but pin-compatible and cost-effective for less demanding applications.
