Description and Introduction

+2.7V, Low-Power, 2-Channel, 108ksps, Serial 12-Bit ADCs in 8-Pin µMAX The **MAX144AEUA+** is a **12-bit, 3.3V, low-power, serial analog-to-digital converter (ADC)** manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 12-bit  
- **Supply Voltage:** 3.0V to 3.6V  
- **Sampling Rate:** Up to **133ksps** (kilo samples per second)  
- **Power Consumption:**  
  - **1.2mW** (at 73ksps, 3V supply)  
  - **0.9mW** (at 50ksps, 3V supply)  
- **Input Voltage Range:** 0V to **VREF** (externally adjustable)  
- **Reference Voltage Range:** 1.0V to **VDD** (3.6V max)  
- **Interface:** **SPI/QSPI/MICROWIRE**-compatible 3-wire serial interface  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **8-pin μMAX (UA)**  

### **Descriptions:**
- The **MAX144AEUA+** is a **low-power**, high-performance **12-bit ADC** designed for **battery-powered and portable applications**.  
- It features an **internal track-and-hold**, eliminating the need for an external sample-and-hold circuit.  
- The device operates from a **single 3.3V supply** and supports an external reference voltage.  
- It is optimized for **low-power consumption**, making it suitable for **medical, industrial, and handheld devices**.  

### **Features:**
- **Low Power:**  
  - **1.2mW** (at 73ksps)  
  - **0.9mW** (at 50ksps)  
- **Small Footprint:** **8-pin μMAX package** (space-saving)  
- **Internal Track-and-Hold:** No external sample-and-hold required  
- **Flexible Reference:** Supports **external reference voltage (1.0V to VDD)**  
- **SPI-Compatible Serial Interface:** Easy interfacing with microcontrollers  
- **Shutdown Mode:** Reduces power consumption further when idle  
- **Wide Operating Temperature Range:** **-40°C to +85°C**  

This ADC is ideal for applications requiring **high resolution, low power, and compact size**, such as **data acquisition, portable instrumentation, and sensor interfaces**.
