Description and Introduction

+2.7V, Low-Power, 2-Channel, 108ksps, Serial 12-Bit ADCs in 8-Pin レMAX The MAX144BCUA is a 12-bit, 8-channel, serial-output analog-to-digital converter (ADC) manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Conversion Time:** 10µs (max)  
- **Sampling Rate:** 100ksps  
- **Input Voltage Range:** 0V to VREF (single-ended), ±VREF/2 (differential)  
- **Reference Voltage:** External (2.5V to VDD)  
- **Supply Voltage (VDD):** +4.75V to +5.25V  
- **Power Consumption:** 5mW (typical)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin µMAX  

### **Descriptions:**
The MAX144BCUA is a low-power, high-speed, 12-bit ADC with an 8-channel multiplexer. It features a successive-approximation register (SAR) architecture and includes a track/hold (T/H) circuit, a precision reference input, and a serial interface for easy microcontroller communication.  

### **Features:**
- **8-Channel Input Multiplexer:** Supports single-ended or differential inputs.  
- **Low Power Consumption:** 5mW (typical).  
- **Internal Track/Hold:** Eliminates the need for an external T/H circuit.  
- **Flexible Reference Input:** Accepts external references from 2.5V to VDD.  
- **SPI-Compatible Serial Interface:** Simplifies digital interfacing.  
- **Small Form Factor:** 8-pin µMAX package for space-constrained applications.  
- **No External Components Required:** Integrated T/H and reference buffer.  

This ADC is suitable for industrial control, data acquisition, and instrumentation applications.
