Description and Introduction

Multi-Range (±10V, ±5V, +10V, +5V), Single +5V, 12-Bit DAS with 8+4 Bus Interface The MAX197BCAI+ is a 12-bit data acquisition system (DAS) 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 analog inputs  
- **Conversion Time:** 6µs (max)  
- **Sampling Rate:** Up to 100ksps  
- **Input Voltage Range:**  
  - ±10V (bipolar mode)  
  - 0V to +10V (unipolar mode)  
- **Interface:** Parallel (8-bit)  
- **Power Supply:**  
  - **Analog Supply (VDD):** +5V ±5%  
  - **Digital Supply (VCC):** +5V ±5%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 28-pin SSOP (Shrink Small Outline Package)  

### **Descriptions:**
The MAX197BCAI+ integrates an 8-channel multiplexer, a high-bandwidth track/hold amplifier, and a 12-bit successive-approximation ADC (SAR ADC). It is designed for precision data acquisition in industrial, medical, and instrumentation applications. The device supports both unipolar and bipolar input ranges and includes an internal reference (4.096V) or allows an external reference.

### **Features:**
- **High-Speed 12-Bit ADC:** 6µs conversion time.  
- **Flexible Input Configuration:** 8 single-ended or 4 differential inputs.  
- **On-Chip Track/Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **Internal/External Reference:** Includes a 4.096V internal reference or supports an external reference.  
- **Low Power Consumption:** 10mW (typical) at 100ksps.  
- **Parallel Interface:** Easy interfacing with microprocessors.  
- **Software-Configurable Unipolar/Bipolar Modes:** Supports ±10V or 0V to +10V input ranges.  

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