Description and Introduction

8-Bit, 76 kSPS ADC Serial Out, On-Chip 20 Ch. Analog Mux, 19 Ch. The TLC545IN is a 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Resolution:** 12-bit  
- **Sampling Rate:** Up to 66 kSPS (kilo-samples per second)  
- **Input Voltage Range:** 0V to Vref (reference voltage dependent)  
- **Supply Voltage:** 4.5V to 6V  
- **Power Consumption:** 8mW (typical)  
- **Interface:** Serial (SPI-compatible)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin PDIP (Plastic Dual In-line Package)  

### **Descriptions:**  
The TLC545IN is a low-power, 12-bit ADC with a serial interface, making it suitable for embedded systems requiring analog signal digitization. It features an internal sample-and-hold circuit and operates with a single power supply.  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Serial Output:** SPI-compatible for easy microcontroller interfacing.  
- **Internal Reference:** Optional external reference for flexibility.  
- **Single-Supply Operation:** Simplifies power requirements.  
- **On-Chip Sample-and-Hold:** Ensures accurate signal capture.  

This information is based on TI's official documentation for the TLC545IN.

Application Scenarios & Design Considerations

8-Bit, 76 kSPS ADC Serial Out, On-Chip 20 Ch. Analog Mux, 19 Ch.

Alternative Part Number

  • ADC0808CCN --: 8-bit successive-approximation ADC in a DIP package with a similar parallel interface, suitable as a functional substitute in many 8-bit ADC applications.
  • MCP3208-CI/P --: 8-channel 12-bit SPI ADC in a DIP package; offers comparable or better resolution and is a common modern replacement when serial interfacing is acceptable.
  • ADC0804LCN --: Single-channel 8-bit ADC in a DIP package with a simple parallel interface, useful as a lower-channel-count alternative for basic analog-to-digital conversion.
