Description and Introduction

60mA 1.5x High-Efficiency White LED Charge Pumps The MAX1912EUB is a 12-bit, 8-channel, serial-output analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Conversion Time:** 3µs (typical)  
- **Sampling Rate:** 250ksps (max)  
- **Input Voltage Range:** 0V to VREF (single-ended), ±VREF (differential)  
- **Reference Voltage:** External (2.5V to VDD)  
- **Supply Voltage (VDD):** 4.5V to 5.5V  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin µMAX (MAX1912EUB)  

### **Descriptions:**  
The MAX1912EUB is a low-power, high-speed, multichannel ADC with a built-in track/hold and a serial interface. It is designed for applications requiring precise analog-to-digital conversion with minimal external components.  

### **Features:**  
- **Low Power Consumption:** 2.5mA (operating), 1µA (shutdown)  
- **Internal Track/Hold:** Eliminates the need for an external sample-and-hold circuit  
- **Flexible Input Configuration:** Supports single-ended or differential inputs  
- **Software-Configurable Unipolar/Bipolar Mode**  
- **Small Footprint:** 10-pin µMAX package  
- **No External Clock Required:** Uses internal clock for conversion  

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