Description and Introduction

8/4/2-Channel, 12-Bit, Simultaneous-Sampling ADCs with ±10V, ±5V, and 0 to +5V Analog Input Ranges The MAX1305 is a 12-bit, multichannel, successive-approximation analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Sampling Rate:** Up to 250ksps  
- **Supply Voltage:** +5V (analog), +2.7V to +5.25V (digital)  
- **Power Consumption:**  
  - 5.5mW (at 250ksps, +5V supply)  
  - 1.7mW (at 100ksps, +3V supply)  
- **Input Voltage Range:** 0V to VREF (single-ended), ±VREF (differential)  
- **Reference Voltage:** External (2.5V to VDD)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 20-pin TSSOP, 20-pin QSOP  

### **Descriptions:**
The MAX1305 is a low-power, high-speed, 12-bit ADC with a flexible input configuration supporting both single-ended and differential inputs. It features an internal track-and-hold circuit and a fast serial interface for easy integration with microcontrollers and DSPs. The device is optimized for applications requiring high accuracy and low power consumption, such as industrial control, data acquisition, and instrumentation.

### **Features:**
- 12-bit resolution with no missing codes  
- 8 single-ended or 4 differential input channels  
- Internal track-and-hold circuit  
- Low power consumption with shutdown mode  
- SPI-compatible serial interface  
- External reference voltage input (2.5V to VDD)  
- Software-selectable unipolar/bipolar input ranges  
- Small footprint packages (TSSOP, QSOP)  
- Wide operating temperature range (-40°C to +85°C)  

This information is based on the manufacturer's datasheet and technical documentation.
