Description and Introduction

8-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROL The TLC0838C is an 8-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Resolution:** 8-bit  
- **Channels:** 8 single-ended or 4 differential inputs  
- **Conversion Time:** 32 µs (max)  
- **Supply Voltage:** 4.5V to 6.3V  
- **Operating Temperature Range:** 0°C to 70°C (commercial grade)  
- **Interface:** Serial (SPI-compatible)  
- **Input Range:** 0V to VCC (single-ended)  
- **Power Consumption:** 15 mW (typical at 5V)  
- **Package Options:** PDIP, SOIC  

### **Descriptions:**
The TLC0838C is a low-power, 8-bit ADC with a serial interface, designed for applications requiring moderate-speed analog-to-digital conversion. It features multiplexed inputs, allowing for single-ended or differential measurements. The device operates with a single power supply and includes an internal sample-and-hold function.

### **Features:**
- **8-Bit Resolution** – Provides 256 discrete output levels.  
- **Flexible Input Configuration** – Supports 8 single-ended or 4 differential inputs.  
- **Serial Output** – SPI-compatible interface for easy microcontroller interfacing.  
- **Internal Sample-and-Hold** – Eliminates the need for an external circuit.  
- **Low Power Consumption** – Suitable for battery-powered applications.  
- **Wide Supply Range** – Operates from 4.5V to 6.3V.  
- **Commercial Temperature Range** – 0°C to 70°C.

Application Scenarios & Design Considerations

8-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROL

Alternative Part Number

  • ADC0838CCN --: Same 8-bit serial ADC function and pinout from the original ADC0838 family that TLC0838C was derived from, widely available and directly interchangeable in most designs.
  • MCP3208-CI/P --: 8-channel 12-bit SPI ADC in a DIP package offering higher resolution and similar serial interface, suitable as a functional upgrade with minor firmware changes.
  • ADC088S102CIMT --: 8-bit 8-channel serial ADC with comparable sampling performance and SPI-compatible interface, usable as an alternative with pinout review.
