Description and Introduction

14-Bit ADC, 200ksps, +5V Single-Supply with Reference The MAX1143ACAP+ is a 10-bit, analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Resolution:** 10-bit  
- **Sampling Rate:** 100ksps (kilo samples per second)  
- **Input Channels:** 4 single-ended or 2 differential  
- **Supply Voltage:** +5V  
- **Power Consumption:** 2.5mW (typical)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 20-pin SSOP (Shrink Small Outline Package)  

### **Descriptions:**
- The MAX1143ACAP+ is a low-power, 10-bit ADC with a successive-approximation register (SAR) architecture.  
- It includes a track/hold (T/H) circuit, voltage reference, and serial interface for easy integration with microcontrollers.  
- Designed for applications requiring moderate resolution and low power consumption.  

### **Features:**
- **Low Power:** 0.5mA operating current (typical)  
- **Internal Reference:** 2.5V or external reference option  
- **Flexible Input Configuration:** Supports single-ended or differential inputs  
- **Small Footprint:** 20-pin SSOP package  
- **No External Components Required:** Built-in T/H and reference  

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

Application Scenarios & Design Considerations

14-Bit ADC, 200ksps, +5V Single-Supply with Reference

Alternative Part Number

  • AD7895ARZ-10 --: 10-bit successive-approximation ADC with similar serial interface and sampling rate, pin-compatible footprint in SOIC, direct functional replacement.
  • LTC1286CS8 --: 12-bit serial ADC with comparable throughput and SPI-compatible interface, suitable substitute when slight resolution upgrade is acceptable.
  • MCP3201-BI/P --: 12-bit SPI ADC in DIP package, widely available and cost-effective alternative for low-speed precision sampling applications.
  • AD7476ARTZ-REEL7 --: Pin-compatible 12-bit SAR ADC in a similar small package with comparable sampling rate and SPI interface, widely available from an established vendor.
  • LTC1286CS8#PBF --: 12-bit serial ADC with similar resolution and SPI-compatible interface, suitable as a functional substitute in many designs.
  • MCP3201-BI/SN --: Low-cost 12-bit SPI ADC with comparable resolution and simple serial interface, good drop-in option for less demanding applications.
