Description and Introduction

+2.7V / Low-Power / 12-Bit Serial ADCs in 8-Pin SO The MAX1240ACSA is a 10-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 10-bit  
- **Sampling Rate:** 100ksps (kilo samples per second)  
- **Input Voltage Range:** 0V to VREF (2.5V to 5.25V)  
- **Power Supply:** Single +5V  
- **Power Consumption:** 2.5mW (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Reference Voltage:** Internal 2.5V or external reference (up to VDD)  
- **Integral Nonlinearity (INL):** ±1 LSB (max)  
- **Differential Nonlinearity (DNL):** ±1 LSB (max)  

### **Description:**
The MAX1240ACSA is a low-power, 10-bit successive-approximation ADC with an internal track-and-hold circuit. It operates from a single +5V supply and includes a serial interface compatible with SPI, QSPI, and MICROWIRE protocols. The device is suitable for battery-powered and data acquisition applications due to its low power consumption.

### **Features:**
- **Low Power:** 2.5mW (typical) at 100ksps  
- **Internal 2.5V Reference** (or external reference support)  
- **No External Components Required** for basic operation  
- **Shutdown Mode** (1µA max) for power savings  
- **SPI/QSPI/MICROWIRE-Compatible** 3-wire serial interface  
- **Small Footprint:** 8-pin SOIC package  

This ADC is commonly used in portable instrumentation, industrial control, and data acquisition systems.
