Description and Introduction

Quad 12-, 14- and 16-Bit Voltage Output SoftSpan DACs with Readback The LTC2704IGW-12 is a 12-bit, quad-channel digital-to-analog converter (DAC) manufactured by Linear Technology (now part of Analog Devices). Below are the key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Resolution:** 12 bits  
- **Number of Channels:** 4  
- **Interface Type:** Serial (SPI/MICROWIRE compatible)  
- **Supply Voltage:** ±5V to ±15V (dual supply) or +5V to +15V (single supply)  
- **Output Type:** Voltage output  
- **Output Range:** Programmable (unipolar or bipolar)  
- **DNL (Differential Nonlinearity):** ±1 LSB (max)  
- **INL (Integral Nonlinearity):** ±4 LSB (max)  
- **Settling Time:** 4.5µs (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead SSOP (GW)  

### **Descriptions:**
- The LTC2704IGW-12 is a high-precision, quad DAC with 12-bit resolution, designed for applications requiring multiple analog outputs.  
- It supports both unipolar (0V to +VREF) and bipolar (±VREF) output ranges, making it versatile for various signal generation needs.  
- The device includes an internal reference buffer, eliminating the need for external buffering.  

### **Features:**
- **Four Independent DACs:** Allows simultaneous or individual updates.  
- **Flexible Output Ranges:** Programmable for unipolar (0V to 5V, 0V to 10V) or bipolar (±5V, ±10V) operation.  
- **Low Glitch Impulse:** Ensures clean output transitions.  
- **Internal Reference:** Integrated reference buffer simplifies design.  
- **SPI/MICROWIRE-Compatible Serial Interface:** Easy interfacing with microcontrollers.  
- **Power-On Reset:** Outputs reset to zero-scale or mid-scale (user-selectable).  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Quad 12-, 14- and 16-Bit Voltage Output SoftSpan DACs with Readback

Alternative Part Number

  • AD5360BSTZ --: Quad 16-bit voltage-output DAC with similar architecture and SPI interface, suitable as a functional replacement in many designs.
  • AD5361BSTZ --: Quad 16-bit DAC from the same Analog Devices family, offering comparable resolution and output range for direct substitution.
  • DAC7718SPAG --: Octal 12-bit voltage-output DAC with SPI, matching the 12-bit resolution and providing a multi-channel alternative from a different vendor.
  • AD5764RBRUZ --: Quad 12-bit voltage-output DAC with internal reference, functionally similar to the LTC2704-12 and from the same parent company, making it a strong drop-in candidate after pinout review.
  • MAX5134AGTG+ --: Quad 12-bit DAC with internal reference and SPI interface, suitable as a lower-cost alternative for similar precision voltage-output needs.
