Description and Introduction

14-Bit ADCs, 150ksps, 3.3V Single Supply The **MAX1144AEAP+** is a high-performance, 14-bit analog-to-digital converter (ADC) manufactured by **MAXIM Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Resolution:** 14-bit  
- **Sampling Rate:** Up to **400 kSPS** (kilo samples per second)  
- **Input Channels:** 4 (single-ended) or 2 (pseudo-differential)  
- **Input Voltage Range:** 0V to **VREF** (programmable reference)  
- **Reference Voltage:** Internal **2.5V** or external (up to **VDD**)  
- **Power Supply:** **+5V** (single supply)  
- **Power Consumption:** **10.5mW** (at 400 kSPS)  
- **Interface:** **SPI**/QSPI™/MICROWIRE™ compatible  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **20-pin SSOP** (Shrink Small Outline Package)  

### **Descriptions:**  
- The MAX1144AEAP+ is a **low-power**, **high-speed**, **14-bit successive-approximation ADC** with an internal track-and-hold (T/H) circuit.  
- It supports **single-ended** or **pseudo-differential** input configurations.  
- Includes an internal **2.5V reference** but allows an external reference for flexibility.  
- Designed for precision applications requiring **low noise** and **high accuracy**.  

### **Features:**  
- **Low Power:** 10.5mW at full speed (400 kSPS), with power-down modes.  
- **Flexible Input Configuration:** 4 single-ended or 2 pseudo-differential channels.  
- **Internal Reference:** 2.5V (±1% initial accuracy).  
- **High-Speed Serial Interface:** SPI-compatible (up to **5MHz** clock).  
- **On-Chip T/H:** Eliminates the need for external sampling circuitry.  
- **Small Footprint:** 20-pin SSOP package for space-constrained designs.  

This information is sourced from the official **MAXIM Integrated datasheet** for the **MAX1144AEAP+**.
