Description and Introduction

Multichannel, True-Differential, Serial, 14-Bit ADCs The MAX1149BEUP is a 10-bit, 8-channel, low-power, successive approximation analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 10-bit  
- **Channels:** 8 single-ended or 4 pseudo-differential  
- **Supply Voltage:** 2.7V to 5.25V  
- **Conversion Rate:** Up to 133ksps (kilo-samples per second)  
- **Power Consumption:**  
  - 1.5mA (at 133ksps, 5V supply)  
  - 0.5mA (at 50ksps, 3V supply)  
  - 2µA (shutdown mode)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Input Voltage Range:** 0V to VREF (externally adjustable)  
- **Reference Voltage:** External (1V to VDD)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin TSSOP  

### **Descriptions:**  
The MAX1149BEUP is a low-power, high-speed, 10-bit ADC designed for applications requiring multiple analog inputs. It features an internal track-and-hold circuit and operates with a single supply voltage, making it suitable for battery-powered and portable devices.  

### **Features:**  
- Low power consumption for battery-operated applications  
- Flexible input configuration (single-ended or pseudo-differential)  
- Internal track-and-hold function  
- SPI-compatible serial interface  
- Software-selectable power-down mode  
- Small 20-pin TSSOP package  

This ADC is commonly used in data acquisition systems, industrial controls, medical instruments, and portable devices.
