Description and Introduction

+5V, Low-Power, Multi-Channel, Serial 8-Bit ADCs The MAX1112CAP is a 12-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:

### **Specifications:**
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Sampling Rate:** Up to 100 kSPS (kilo-samples per second)  
- **Input Voltage Range:** 0V to VREF (programmable reference)  
- **Reference Voltage:** Internal 4.096V or external (2V to VDD)  
- **Supply Voltage (VDD):** +2.7V to +5.25V  
- **Power Consumption:**  
  - 2.5mW (at 100 kSPS, VDD = 3V)  
  - 8mW (at 100 kSPS, VDD = 5V)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Package:** 20-pin SSOP (Shrink Small Outline Package)  

### **Descriptions:**  
The MAX1112CAP is a low-power, 12-bit successive-approximation ADC with an internal track/hold (T/H) circuit. It supports both single-ended and differential input configurations, making it suitable for various signal acquisition applications. The device operates with a single supply and includes a software-configurable reference (internal or external).  

### **Features:**  
- **Low Power:** Auto-shutdown mode reduces power consumption.  
- **Flexible Input Configuration:** 8 single-ended or 4 differential channels.  
- **Internal Reference:** 4.096V with ±1% accuracy.  
- **SPI-Compatible Interface:** Easy interfacing with microcontrollers.  
- **No External Components Required:** Built-in T/H and reference.  
- **Small Footprint:** 20-pin SSOP package.  

This information is strictly based on the manufacturer's datasheet. For detailed electrical characteristics and application guidelines, refer to the official documentation.

Application Scenarios & Design Considerations

+5V, Low-Power, Multi-Channel, Serial 8-Bit ADCs

Alternative Part Number

  • ADC0832CCN --: 8-bit serial ADC with similar SPI-like interface and 2-channel input, widely available and pin-compatible in function for many MAX1112 applications.
  • MCP3202-CI/P --: 12-bit SPI ADC with 2 single-ended channels, higher resolution than MAX1112 and easy drop-in for low-speed sensing designs.
  • LTC1286CN8 --: 12-bit serial ADC with similar sampling rate and single-supply operation, suitable functional replacement when board layout allows.
  • ADC0838CCN --: 8-channel 8-bit serial ADC with similar functionality and pin-compatible interface, widely available and cost-effective.
  • TLC0838CN --: 8-bit 8-channel serial ADC in DIP package, functionally equivalent to the MAX1112 with similar SPI interface.
  • MCP3208-CI/P --: 12-bit 8-channel SPI ADC in DIP package offering higher resolution and comparable serial interface, suitable as an upgrade.
  • AD7811ARZ --: Similar 10-bit serial ADC with comparable sampling rate and SPI interface, from a different series and manufacturer, suitable as a functional replacement.
  • TLC2543CN --: 11-channel 12-bit serial ADC with SPI interface, widely available and functionally similar, providing a viable alternative from a different series.
