Description and Introduction

Single Chip 12-Bit Data Acquisition System The LTC1294CCSW is a 12-bit data acquisition system manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 12-bit  
- **Number of Channels:** 2 differential or 4 single-ended  
- **Interface:** SPI/Microwire compatible  
- **Supply Voltage:** 4.75V to 9V (single supply)  
- **Conversion Time:** 10µs (typical)  
- **Sampling Rate:** 100ksps (max)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 16-Lead SOIC (SW)  

### **Descriptions:**
- The LTC1294CCSW is a low-power, 12-bit successive approximation ADC with a built-in sample-and-hold.  
- It supports both single-ended and differential input configurations.  
- Designed for precision data acquisition in industrial, automotive, and instrumentation applications.  

### **Features:**
- **Low Power Consumption:** 1.5mA (typical) at 5V  
- **Internal Reference:** 2.5V (typical)  
- **No Missing Codes Guaranteed**  
- **Single-Supply Operation**  
- **SPI/Microwire-Compatible Serial Interface**  
- **Shutdown Mode for Power Savings**

Application Scenarios & Design Considerations

Single Chip 12-Bit Data Acquisition System

Alternative Part Number

  • AD7874AN --: Similar 12-bit successive-approximation ADC with 8-channel multiplexer and serial interface, functionally comparable to the LTC1294.
  • MAX186ACPP --: 8-channel 12-bit serial ADC with comparable sampling rate and interface, suitable as a functional replacement.
  • TLC2543CN --: 11-channel 12-bit serial ADC with similar SPI interface and performance class, usable as an alternative with minor design adjustments.
  • ADC128S102CIMM --: 12-bit 8-channel SAR ADC with SPI interface, functionally similar to the LTC1294 and widely available from an alternate vendor.
  • MCP3208-CI/SL --: 12-bit 8-channel SPI ADC in SOIC, pin-function compatible for many LTC1294 designs and easy to source.
  • ADS7844E --: 12-bit 8-channel serial ADC with similar resolution and channel count, suitable as a drop-in functional replacement in many applications.
