Description and Introduction

+2.7V / Low-Power / Multichannel / Serial 8-Bit ADCs The MAX1111EEE is a 12-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Resolution:** 12-bit  
- **Channels:** 1 (single-ended)  
- **Sampling Rate:** Up to **250 kSPS** (kilo samples per second)  
- **Input Voltage Range:** 0V to **VREF** (reference voltage dependent)  
- **Supply Voltage:** **+5V** (single supply)  
- **Interface:** **SPI/QSPI™/MICROWIRE™** compatible  
- **Power Consumption:**  
  - **2.5mW** (at 250 kSPS)  
  - **1µA** (shutdown mode)  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **16-pin QSOP**  

### **Descriptions:**  
The MAX1111EEE is a low-power, high-speed, 12-bit successive-approximation ADC. It features an internal track-and-hold (T/H) circuit and operates from a single +5V supply. The device is designed for applications requiring high-speed data acquisition with minimal power consumption.  

### **Features:**  
- **Single +5V Supply Operation**  
- **Internal 4.096V Reference** (or external reference option)  
- **Low Power:**  
  - **2.5mW** (normal operation)  
  - **1µA** (shutdown mode)  
- **SPI/QSPI/MICROWIRE-Compatible Serial Interface**  
- **Internal Track-and-Hold (T/H) Circuit**  
- **Small 16-Pin QSOP Package**  
- **Pin-Compatible with 10-Bit MAX1110**  

This ADC is suitable for **battery-powered systems, data acquisition, industrial controls, and instrumentation** due to its low power consumption and high-speed performance.  

*(Note: Maxim Integrated is now part of Analog Devices, but the original part number remains unchanged.)*

Application Scenarios & Design Considerations

+2.7V / Low-Power / Multichannel / Serial 8-Bit ADCs

Alternative Part Number

  • ADC0832CCN --: 8-bit serial ADC with similar resolution and SPI-like interface, widely available and cost-effective substitute for low-speed sensing applications.
  • MCP3202-CI/P --: 12-bit SPI ADC with comparable channel count and supply range, offering better resolution and easy drop-in for many MAX1111 designs.
  • LTC1286CN8 --: 12-bit serial ADC in DIP package with similar sampling rate and interface, suitable when higher accuracy is needed.
  • ADC0838CCN --: 8-bit serial ADC with similar multiplexed input architecture, widely available and pin-compatible in function for many designs.
  • TLC0838CN --: 8-bit successive-approximation ADC with 8-channel multiplexer, close functional match to the MAX1111 in DIP package.
  • MCP3208-CI/P --: 12-bit SPI ADC with 8-channel multiplexer, higher resolution drop-in functional alternative for most MAX1111 applications.
  • MCP3202-BI/P --: 12-bit SPI ADC in DIP package offering higher resolution than the original, pin-compatible style interface and easy drop-in for many MAX1111 designs.
