Description and Introduction

8-/4-/2-Channel, 14-Bit, Simultaneous-Sampling ADCs with 10V, 5V, and 0 to +5V Analog Input Ranges The MAX1321ECM is a high-voltage, low-power, 12-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 12-bit  
- **Input Voltage Range:** 0V to VREF (programmable up to ±12V)  
- **Supply Voltage:** +5V (analog), +2.7V to +5.25V (digital)  
- **Power Consumption:** 1.5mW (typical)  
- **Sampling Rate:** 100ksps (max)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 48-pin TQFP  

### **Descriptions:**
The MAX1321ECM is a low-power, high-voltage ADC designed for precision measurement applications. It integrates a 12-bit SAR ADC with a high-voltage input multiplexer, allowing direct measurement of signals up to ±12V. The device operates with a single +5V analog supply and a flexible digital supply, making it suitable for battery-powered and industrial systems.

### **Features:**
- **High-Voltage Input Multiplexer:** Supports up to ±12V inputs  
- **Low-Power Operation:** Ideal for portable and battery-powered applications  
- **Programmable Gain Amplifier (PGA):** Adjustable gain settings for signal conditioning  
- **Internal Reference:** 2.5V or external reference option  
- **SPI-Compatible Serial Interface:** Easy integration with microcontrollers  
- **On-Chip Calibration:** Ensures accuracy over temperature and voltage variations  
- **Flexible Power Modes:** Includes shutdown mode for power savings
