Description and Introduction

Low-Power, 8-Channel, Serial 12-Bit ADCs The MAX186CEAP is a 12-bit data acquisition system (DAS) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 pseudo-differential  
- **Conversion Time:** 10μs (max)  
- **Sampling Rate:** 133ksps  
- **Input Voltage Range:** 0V to VREF (unipolar) or ±VREF/2 (bipolar)  
- **Reference Voltage:** Internal (4.096V) or external (1V to VDD)  
- **Supply Voltage:** +5V (±5%)  
- **Power Consumption:** 2.5mA (operating), 2μA (shutdown)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 20-pin SSOP  

### **Descriptions and Features:**  
- **Integrated ADC with Multiplexer:** Combines an 8-channel multiplexer, a high-bandwidth track/hold, and a 12-bit successive-approximation ADC.  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Flexible Input Configuration:** Supports both single-ended and pseudo-differential inputs.  
- **Internal or External Reference:** Includes a 4.096V internal reference or accepts an external reference.  
- **Serial Interface:** Compatible with SPI, QSPI, and MICROWIRE for easy microcontroller interfacing.  
- **Software-Configurable:** Allows adjustment of input range, clock speed, and power modes.  
- **Shutdown Mode:** Reduces power consumption to 2μA when inactive.  

This device is commonly used in data logging, industrial control, and instrumentation applications.
