Description and Introduction

3V Micropower Sampling 12-Bit A/D Converters in SO-8 Packages The LTC1285IS8 is a 12-bit serial I/O A/D converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 12-bit  
- **Supply Voltage:** 5V  
- **Sampling Rate:** Up to 50kHz  
- **Input Channels:** 1 differential or 2 single-ended  
- **Interface:** Serial (SPI-compatible)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (IS8)  
- **Power Consumption:** Low power (typically 1.5mW at 5V)  
- **Reference Voltage:** External (requires an external reference)  

### **Descriptions and Features:**  
- **12-bit Resolution:** Provides accurate analog-to-digital conversion.  
- **Serial Interface:** SPI-compatible for easy microcontroller interfacing.

Application Scenarios & Design Considerations

3V Micropower Sampling 12-Bit A/D Converters in SO-8 Packages

Alternative Part Number

  • ADC0832CCN --: 8-bit serial ADC with similar SPI-like interface and DIP/SOIC options, widely available and pin-compatible in function.
  • MCP3202-CI/SN --: 12-bit dual-channel SPI ADC in SOIC-8, higher resolution drop-in functional replacement for low-speed sensing.
  • ADS7822E --: 12-bit micropower SPI ADC in small package, comparable sampling rate and serial interface for similar applications.
  • MCP3202-CI/P --: 12-bit dual-channel SPI ADC offering higher resolution and similar serial interface, suitable drop-in functional replacement.
  • ADS7822UB --: 12-bit micropower SPI ADC with comparable sampling rate and small package, good alternative for low-power designs.
