Description and Introduction

10-Bit, 38 kSPS ADC Serial Out, On-Chip System Clock, 11 Ch. 20-SSOP The TLC1543CDBG4 is a 10-bit, 11-channel analog-to-digital converter (ADC) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Resolution:** 10-bit  
- **Channels:** 11 (10 external + 1 internal)  
- **Interface:** Serial (SPI-compatible)  
- **Supply Voltage:** 4.5V to 5.5V  
- **Conversion Time:** 21µs (max)  
- **Sampling Rate:** 38kSPS (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SSOP-20  

### **Descriptions:**  
The TLC1543CDBG4 is a successive approximation (SAR) ADC with an onboard sample-and-hold circuit. It provides 11 input channels (10 external, 1 internal for self-test) and communicates via a 3-wire serial interface. It is designed for low-power, high-speed data acquisition applications.  

### **Features:**  
- **10-bit resolution**  
- **11 analog input channels**  
- **Built-in sample-and-hold**  
- **SPI-compatible serial interface**  
- **Low power consumption (1mW typical)**  
- **Internal system self-test capability**  
- **Wide operating voltage range (4.5V to 5.5V)**  
- **Industrial temperature range (-40°C to +85°C)**  

This ADC is commonly used in industrial control, data acquisition, and instrumentation applications.

Application Scenarios & Design Considerations

10-Bit, 38 kSPS ADC Serial Out, On-Chip System Clock, 11 Ch. 20-SSOP

Alternative Part Number

  • ADC0838CCN --: 10-bit serial ADC with similar resolution and SPI-like interface, pin-compatible in many designs and widely available.
  • MCP3208-CI/P --: 12-bit 8-channel SPI ADC offering higher resolution and similar functionality, suitable drop-in replacement with minor firmware changes.
  • ADS7841E --: 12-bit 4-channel serial ADC with comparable sampling rate and interface, good alternative when higher resolution is acceptable.
