Description and Introduction

High-Speed 12-Bit A/D Converters With External Refernce input The MAX185ACWG is a 12-bit, 8-channel, serial output 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  
- **Channels:** 8 single-ended or 4 differential  
- **Conversion Time:** 10µs (max)  
- **Sampling Rate:** 100ksps (max)  
- **Input Voltage Range:** 0V to VREF (single-ended), ±VREF (differential)  
- **Reference Voltage:** External (2.5V to VDD)  
- **Supply Voltage (VDD):** +5V ±10%  
- **Power Consumption:** 7.5mW (typical)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 24-pin SOIC (Wide)  

### **Descriptions:**
The MAX185ACWG is a low-power, high-speed, 12-bit ADC with an 8-channel multiplexer. It features a successive-approximation register (SAR) architecture and includes a track/hold circuit, clock oscillator, and serial interface. It is designed for applications requiring precision analog-to-digital conversion with minimal power consumption.

### **Features:**
- **8-Channel Multiplexer:** Supports single-ended or differential inputs.  
- **Low Power:** 7.5mW typical power consumption.  
- **Internal Track/Hold:** Eliminates the need for external circuitry.  
- **Serial Interface:** Compatible with SPI, QSPI, and MICROWIRE protocols.  
- **Flexible Reference Input:** Allows external reference voltage adjustment.  
- **Single +5V Supply Operation:** Simplifies power requirements.  
- **Software-Configurable Unipolar/Bipolar Modes:** Supports different input ranges.  

This information is based solely on the manufacturer's datasheet and specifications.
