Description and Introduction

+2.7V to %.25V, Low-Power, 10-Bit Serial ADCs in SO-8 The MAX1242BESA is a 12-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 12-bit  
- **Sampling Rate:** 100ksps (kilo samples per second)  
- **Input Channels:** 1 single-ended or 1 differential  
- **Supply Voltage:** +2.7V to +5.25V  
- **Power Consumption:** 1.5mA (operating), 2µA (power-down mode)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible 3-wire serial  
- **Input Voltage Range:** 0V to VREF (single-ended), ±VREF (differential)  
- **Reference Voltage:** Internal 2.5V or external (up to VDD)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**
The MAX1242BESA is a low-power, 12-bit ADC designed for applications requiring high accuracy and minimal power consumption. It features an internal track/hold, voltage reference, and serial interface, making it suitable for battery-powered and space-constrained systems.

### **Features:**
- **Low Power Consumption:** 1.5mA (active), 2µA (shutdown)  
- **Internal Reference:** 2.5V with ±1% accuracy  
- **Flexible Power Supply:** Operates from +2.7V to +5.25V  
- **SPI-Compatible Serial Interface:** 3-wire communication  
- **Small Footprint:** 8-pin SOIC package  
- **Software-Configurable:** Unipolar/Bipolar, single-ended/differential inputs  
- **Internal Track/Hold:** Eliminates need for external circuitry  
- **Power-Down Mode:** Reduces current consumption when idle  

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