Description and Introduction

Multichannel, True-Differential, Serial, 14-Bit ADCs The MAX1149BCUP+ is a 14-bit, 8-channel, successive approximation analog-to-digital converter (ADC) manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 14-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Conversion Rate:** Up to 250 kSPS (kilo samples per second)  
- **Input Voltage Range:** 0V to VREF (programmable reference range)  
- **Reference Voltage:** Internal 4.096V or external reference (2.5V to VDD)  
- **Supply Voltage (VDD):** +5V ±10%  
- **Power Consumption:**  
  - 5.5mW (at 250 kSPS)  
  - 1.5µA (shutdown mode)  
- **Interface:** SPI/QSPI™/MICROWIRE™ compatible  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-TSSOP  

### **Descriptions:**
- The MAX1149BCUP+ integrates a high-speed 14-bit ADC with a flexible input multiplexer, allowing single-ended or differential measurements.  
- It features an internal reference (4.096V) but supports an external reference for greater flexibility.  
- The device includes a track/hold amplifier, ensuring accurate signal acquisition during conversion.  
- Low power consumption makes it suitable for battery-powered applications.  

### **Features:**
- **High Accuracy:** 14-bit resolution with no missing codes  
- **Low Power:** Optimized for power-sensitive applications  
- **Flexible Input Configuration:** Supports single-ended or differential inputs  
- **Internal or External Reference:** Programmable reference options  
- **SPI-Compatible Interface:** Easy integration with microcontrollers  
- **Shutdown Mode:** Reduces power consumption to 1.5µA  
- **Wide Operating Temperature Range:** -40°C to +85°C  

This ADC is commonly used in industrial control, data acquisition, medical instruments, and portable devices requiring high-resolution analog conversion.
