Description and Introduction

+3V / 18-Bit / Low-Power / Multichannel / Oversampling Sigma-Delta ADC The MAX1403EAI is a multichannel, low-power, 16-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on available factual data:

### **Specifications:**
- **Resolution:** 16-bit  
- **Channels:** 8 fully differential or 16 single-ended inputs  
- **Sampling Rate:** Up to 480 samples per second (sps)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Supply Voltage:** +5V (analog), +2.7V to +5.25V (digital)  
- **Power Consumption:**  
  - 2.5mW (normal mode)  
  - 25µW (power-down mode)  
- **Input Voltage Range:** ±VREF (programmable)  
- **Reference Voltage:** Internal (2.5V) or external (up to ±2.5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SSOP  

### **Descriptions:**
The MAX1403EAI is a highly integrated, low-power, multichannel ADC designed for precision data acquisition in industrial, medical, and instrumentation applications. It includes a PGA (Programmable Gain Amplifier), a multiplexer, and an onboard reference, reducing external component requirements.  

### **Features:**
- **16-bit Sigma-Delta ADC** with high accuracy  
- **Programmable Gain (1 to 128)** for signal conditioning  
- **Low Noise:** 1.5µV RMS (at 19.2Hz output rate)  
- **Flexible Input Configuration:** Supports differential or single-ended inputs  
- **On-Chip Calibration:** Includes self and system calibration modes  
- **SPI-Compatible Serial Interface** for easy microcontroller interfacing  
- **Internal Clock or External Clock Option**  
- **Power-Saving Modes:** Reduces energy consumption in battery-operated systems
