Description and Introduction

Multichannel, True-Differential, Serial, 14-Bit ADCs The MAX1147BEUP is a 14-bit, multichannel, successive approximation analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 14-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Sampling Rate:** Up to 250 kSPS (kilo samples per second)  
- **Input Voltage Range:** 0V to VREF (programmable)  
- **Reference Voltage:** Internal 4.096V or external (up to VDD)  
- **Supply Voltage:** 2.7V to 3.6V (analog), 1.7V to 3.6V (digital)  
- **Power Consumption:** 3.5mW (at 250 kSPS, 3V supply)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-TSSOP  

### **Descriptions:**  
The MAX1147BEUP is a low-power, high-precision ADC with an internal reference and flexible input configuration. It supports both single-ended and differential inputs, making it suitable for industrial, medical, and instrumentation applications.  

### **Features:**  
- True differential or single-ended inputs  
- Programmable gain (1x to 8x)  
- Internal 4.096V reference (±10mV initial accuracy)  
- Low power consumption with shutdown mode  
- SPI-compatible serial interface  
- On-chip FIFO for data storage  
- Internal clock or external clock option  

This ADC is designed for applications requiring high resolution and low power consumption, such as sensor interfaces, data acquisition systems, and portable instrumentation.
