Description and Introduction

Single Chip 12-Bit Data Acquisition System The **LTC1290CIN** is a 12-bit data acquisition system manufactured by **Linear Technology (now part of Analog Devices)**.  

### **Key Specifications:**  
- **Resolution:** 12-bit  
- **Input Channels:** 2 differential or 4 single-ended  
- **Conversion Time:** 10µs (typical)  
- **Supply Voltage:** ±5V (dual supply) or +5V (single supply)  
- **Interface:** SPI/Microwire compatible  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions and Features:**  
- **12-bit SAR ADC:** Successive Approximation Register (SAR) architecture for accurate conversions.  
- **Flexible Input Configuration:** Supports 2 fully differential or 4 single-ended inputs.  
- **Low Power Consumption:** Typically 5mW (±5V supply).  
- **On-Chip Sample-and-Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **SPI-Compatible Serial Interface:** Easy interfacing with microcontrollers and processors.  
- **Internal Clock:** No external clock required for conversions.  
- **Wide Operating Range:** Suitable for industrial and automotive applications.  

This part is designed for precision data acquisition in embedded systems, industrial controls, and instrumentation.

Application Scenarios & Design Considerations

Single Chip 12-Bit Data Acquisition System

Alternative Part Number

  • ADC128S102CIMM --: 12-bit 8-channel serial ADC with similar SPI interface and function, widely available and pin-compatible in many designs.
  • MCP3208-CI/P --: 12-bit 8-channel SPI ADC in DIP package, functionally similar and easy drop-in for many LTC1290 applications.
  • ADS7841E --: 12-bit 4-channel serial ADC with comparable sampling performance and interface, suitable as a functional substitute.
  • ADC0848CCN --: 8-bit 8-channel successive-approximation ADC in a DIP package, functionally similar to the LTC1290 and widely available as a drop-in style replacement.
  • MAX186CCPI --: 8-channel 12-bit serial ADC in a DIP package with comparable resolution and interface, suitable for designs needing higher precision than the LTC1290.
  • TLC1549CP --: 10-bit serial ADC in a DIP package with a simple serial interface, offering a lower-cost alternative for less demanding applications.
