Description and Introduction

+3V / 18-Bit / Low-Power / Multichannel / Oversampling Sigma-Delta ADC The MAX1403CAI is a multichannel, low-power, 16-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 16-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Supply Voltage:** +2.7V to +3.6V (analog), +2.7V to +5.25V (digital)  
- **Power Consumption:** 1.5mA (operating), 2µA (power-down mode)  
- **Sampling Rate:** Up to 480 samples per second (sps)  
- **Input Voltage Range:** ±VREF (programmable)  
- **Reference Voltage:** Internal (2.5V) or external (up to ±VDD)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SSOP  

### **Descriptions:**
The MAX1403CAI is a highly integrated, low-power, multichannel ADC designed for precision data acquisition in industrial, medical, and instrumentation applications. It includes a flexible input multiplexer, a programmable gain amplifier (PGA), and an internal voltage reference. Its low power consumption and high resolution make it suitable for battery-powered systems.

### **Features:**
- **16-bit resolution with no missing codes**  
- **Programmable gain (1x to 128x)**  
- **Internal or external reference option**  
- **On-chip calibration for offset and gain error**  
- **SPI-compatible serial interface**  
- **Low-power shutdown mode (2µA)**  
- **Simultaneous 50Hz/60Hz rejection**  
- **Rail-to-rail input buffer**  

The MAX1403CAI is optimized for applications requiring high accuracy and low power consumption, such as sensor interfaces, portable instrumentation, and industrial control systems.
