Description and Introduction

Single Chip 12-Bit Data Acquisition System The LTC1290BCN is a 12-bit data acquisition system manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Resolution:** 12-bit  
- **Input Channels:** 2 differential or 4 single-ended  
- **Conversion Time:** 10µs  
- **Supply Voltage:** ±5V (dual supply) or single +5V supply  
- **Power Consumption:** 75mW (typical)  
- **Interface:** Serial (SPI/Microwire compatible)  
- **Operating Temperature Range:** 0°C to 70°C (commercial grade)  
- **Package:** 16-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**
- The LTC1290BCN is a 12-bit successive approximation analog-to-digital converter (ADC) with a built-in sample-and-hold circuit.  
- It supports both differential and single-ended input configurations.  
- Designed for low-power applications, it operates with a single +5V supply or dual ±5V supplies.  
- It includes a serial interface compatible with SPI and Microwire protocols for easy microcontroller interfacing.  

### **Features:**
- **12-Bit Resolution** – Provides accurate analog-to-digital conversion.  
- **Flexible Input Configurations** – Supports 2 differential or 4 single-ended inputs.  
- **Fast Conversion Time** – 10µs conversion speed for real-time applications.  
- **Low Power Consumption** – 75mW typical power dissipation.  
- **On-Chip Sample-and-Hold** – Eliminates the need for an external sample-and-hold circuit.  
- **Serial Interface** – SPI/Microwire compatible for simplified digital interfacing.  
- **Wide Supply Range** – Operates from a single +5V or dual ±5V supply.  

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

Application Scenarios & Design Considerations

Single Chip 12-Bit Data Acquisition System

Alternative Part Number

  • ADC0848CCN --: 8-bit successive-approximation ADC in a DIP package with a similar parallel interface, suitable as a functional substitute in many data-acquisition designs.
  • MAX186BCPI --: Serial 12-bit ADC with 8-channel multiplexer in a DIP package, offering comparable resolution and channel count for similar measurement applications.
  • AD7874AN --: 12-bit ADC in a DIP package with a similar analog front-end role, usable as an alternative when board-level rework is acceptable.
  • ADC128S102CIMM --: 12-bit 8-channel serial ADC with similar SPI interface and functionality, suitable replacement for general data acquisition applications.
  • MCP3208-CI/P --: 12-bit 8-channel SPI ADC in DIP package, pin-function compatible for many LTC1290 use cases with lower cost.
  • ADS7841E --: 12-bit 4-channel serial ADC offering comparable resolution and serial interface, usable where fewer channels are acceptable.
