Description and Introduction

+2.7V to %.25V, Low-Power, 10-Bit Serial ADCs in SO-8 The MAX1243BCSA is a 10-bit analog-to-digital converter (ADC) from Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Resolution:** 10-bit  
- **Input Channels:** 4 single-ended or 2 differential  
- **Supply Voltage:** +2.7V to +5.25V  
- **Conversion Time:** 2.4µs (max)  
- **Sampling Rate:** Up to 133ksps  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX1243BCSA is a low-power, 10-bit ADC with a successive approximation register (SAR) architecture. It features a built-in track/hold, voltage reference, and serial interface, making it suitable for space-constrained and power-sensitive applications.  

### **Features:**  
- Low power consumption (1.2mA at 133ksps, 2µA in shutdown mode)  
- Internal 2.5V reference or external reference support  
- Software-selectable unipolar/bipolar input ranges  
- No external components required for operation  
- Small 8-pin SOIC package

- **Package:** 8-pin SOIC  

### **Descriptions:**
The MAX1243BCSA is a low-power, 12-bit successive approximation ADC with an internal track-and-hold circuit. It is designed for applications requiring high-speed, low-power data conversion with a small footprint. The device operates from a single supply and includes a flexible serial interface for easy microcontroller integration.

### **Features:**
- **Low Power:** Ideal for battery-powered applications.  
- **Internal Reference:** 2.5V reference with ±1% accuracy.  
- **Flexible Input Configuration:** Supports single-ended or differential inputs.  
- **Fast Conversion Time:** 7.5µs per conversion.  
- **SPI-Compatible Interface:** Simplifies digital interfacing.  
- **Small Form Factor:** 8-pin SOIC package saves board space.  

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