Description and Introduction

3V 140ksps 12-Bit Sampling A/D Converter with Reference The LTC1282BCSW#PBF is a 12-bit serial I/O A/D converter manufactured by Linear Technology (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Resolution:** 12-bit  
- **Input Channels:** 2 (multiplexed)  
- **Conversion Time:** 20µs  
- **Supply Voltage:** Single +5V supply  
- **Power Consumption:** 1.5mW (typical)  
- **Input Voltage Range:** 0V to VREF (external reference)  
- **Reference Voltage:** External (up to VCC)  
- **Interface:** 3-wire SPI/MICROWIRE compatible  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 16-pin SOIC (SW)  

### **Descriptions:**
The LTC1282BCSW#PBF is a low-power, 12-bit successive approximation ADC with a built-in sample-and-hold. It features two multiplexed analog inputs and communicates via a 3-wire serial interface compatible with SPI and MICROWIRE protocols. The device operates from a single +5V supply and includes an onboard clock, eliminating the need for external timing components.

### **Features:**
- **12-bit resolution with no missing codes**  
- **Two single-ended or one differential input**  
- **Internal sample-and-hold**  
- **Low power consumption (1.5mW typical)**  
- **Single +5V supply operation**  
- **SPI/MICROWIRE compatible serial interface**  
- **Built-in clock (no external components required)**  
- **External reference voltage (up to VCC)**  
- **16-pin SOIC package**  

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

Application Scenarios & Design Considerations

3V 140ksps 12-Bit Sampling A/D Converter with Reference

Alternative Part Number

  • AD7874ARZ --: Similar 12-bit successive-approximation ADC with parallel interface in a wide SOIC package; same signal chain role and comparable speed/accuracy.
  • MAX186ACWI+ --: 12-bit multi-channel ADC with serial interface and similar supply range; suitable functional substitute when board layout allows interface change.
  • ADS7841E --: 12-bit SAR ADC with comparable resolution and sampling rate in a small package; cost-effective alternative for general-purpose data acquisition.
  • AD7872JRZ --: 12-bit successive-approximation ADC with similar parallel interface and performance class, from the same parent company as Linear Technology.
  • MAX187BCPA+ --: 12-bit serial ADC offering comparable resolution and accuracy, suitable as a functional substitute in many data-acquisition designs.
