Description and Introduction

Multi-Range (±10V, ±5V, +10V, +5V), Single +5V, 12-Bit DAS with 8+4 Bus Interface The MAX197ACNI+ 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:** 100ksps (kilo-samples per second)  
- **Input Voltage Range:** ±10V, ±5V, 0 to +10V, or 0 to +5V (software-selectable)  
- **Interface:** Parallel (8-bit µP-compatible)  
- **Supply Voltage:** ±5V  
- **Power Consumption:** 100mW (typical)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 28-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**
- The MAX197ACNI+ integrates an 8-channel multiplexer, a high-bandwidth track/hold, and a 12-bit successive-approximation ADC (Analog-to-Digital Converter).  
- It features software-selectable input ranges, allowing flexible interfacing with various signal sources.  
- The device includes an internal 4.096V reference, but an external reference can also be used for improved accuracy.  
- It is designed for industrial control, data acquisition, and instrumentation applications.  

### **Features:**
- **8-Channel Multiplexer:** Supports single-ended or differential inputs.  
- **Internal Track/Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **Programmable Input Range:** Allows selection of different voltage ranges (±10V, ±5V, 0 to +10V, or 0 to +5V).  
- **On-Chip Reference:** 4.096V internal reference with ±1% accuracy.  
- **Parallel µP Interface:** Easy interfacing with microprocessors and microcontrollers.  
- **Low Power Consumption:** 100mW typical operation.  
- **Overvoltage Protection:** Tolerant up to ±16.5V on analog inputs.

Multi-Range (±10V, ±5V, +10V, +5V), Single +5V, 12-Bit DAS with 8+4 Bus Interface The MAX197ACNI+ is a 12-bit, 8-channel data acquisition system (DAS) manufactured by Maxim Integrated (formerly Dallas Semiconductor). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 pseudo-differential  
- **Conversion Time:** 6µs (max)  
- **Throughput Rate:** 100ksps  
- **Input Voltage Range:** 0V to VREF (software-selectable ±10V, ±5V, 0 to 10V, 0 to 5V)  
- **Reference Voltage:** Internal 4.096V or external (up to VDD)  
- **Power Supply:** +5V ±5%  
- **Power Consumption:** 10mA (operating), 2µA (power-down mode)  
- **Interface:** Parallel (8-bit µP-compatible)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin PDIP  

### **Descriptions:**  
The MAX197ACNI+ integrates an 8-channel multiplexer, high-bandwidth track/hold, and a 12-bit successive-approximation ADC. It features software-configurable input ranges and operates from a single +5V supply.  

### **Features:**  
- **Flexible Input Ranges:** Software-selectable unipolar/bipolar ranges.  
- **Low Power:** 10mA operating current, 2µA shutdown mode.  
- **Internal/External Reference:** 4.096V internal reference or external reference support.  
- **No External Components Required:** Includes track/hold and reference.  
- **Parallel Interface:** Easy interfacing with microprocessors.  
- **Power-Down Mode:** Reduces power consumption when idle.
