Description and Introduction

8-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROL AND 11 INPUTS The TLC540I is a 9-bit analog-to-digital converter (ADC) manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Resolution:** 9-bit  
- **Sampling Rate:** Up to 400 kSPS (kilo-samples per second)  
- **Input Voltage Range:** 0V to Vref (Reference Voltage)  
- **Supply Voltage:** 4.5V to 6.3V  
- **Power Consumption:** 10 mW (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** PDIP (Plastic Dual In-Line Package), SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
The TLC540I is a low-power, high-speed, 9-bit successive approximation register (SAR) ADC. It includes an on-chip sample-and-hold circuit and operates with a single +5V supply. It is designed for applications requiring moderate resolution and high-speed conversion.  

### **Features:**  
- **9-Bit Resolution**  
- **Fast Conversion Time:** 2.5 µs (microseconds)  
- **On-Chip Sample-and-Hold Function**  
- **Single +5V Power Supply Operation**  
- **Low Power Consumption (10 mW typical)**  
- **Wide Operating Temperature Range (-40°C to +85°C)**  
- **Available in PDIP and SOIC Packages**  

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

Application Scenarios & Design Considerations

8-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROL AND 11 INPUTS

Alternative Part Number

  • ADC0804LCN --: 8-bit successive-approximation ADC with similar resolution and parallel interface, widely available and pin-compatible in function for many TLC540 applications.
  • MCP3208-CI/P --: 8-channel 12-bit SPI ADC offering higher resolution and flexible serial interface, suitable as a functional upgrade when board layout allows interface changes.
  • ADC0838CCN --: 8-bit serial I/O ADC with multiplexed inputs, similar conversion architecture and supply range, usable as a lower-pin-count alternative with minor interface redesign.
