TLC0838CDWR

Analog To Digital Converters (ADC) Overview

The TLC0838CDWR is an 8-bit analog-to-digital converter (ADC) manufactured by Texas Instruments, housed in a 20-pin SOIC package. It features a successive approximation architecture with a maximum sampling rate of 31 kSPS and operates on a single 4.5 V to 5.5 V supply. The device supports serial SPI-compatible interfaces for data output and control. It includes an internal multiplexer allowing for eight single-ended or differential input channels. Key performance metrics include a typical power consumption of 3 mW and linearity errors (DNL/INL) within +/- 0.4 LSB.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer supporting single-ended, pseudo-differential, and differential input configurations.
• Utilizes a serial interface compatible with standard SPI protocols for simplified microprocessor connectivity.
• Operates from a single low-voltage power supply ranging from 4.5 V to 5.5 V.
• Features external reference capability to accommodate various system voltage requirements.

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CDWR' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the operating temperature range meets the application's thermal requirements. Ensure the external reference voltage source matches the ADC's input specifications for optimal accuracy. Check for RoHS compliance status if required by regulatory standards.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and moderate speed are sufficient for the signal chain. Consider the 20-pin SOIC footprint for PCB layout constraints. Evaluate the need for differential inputs versus single-ended signals to utilize the internal multiplexer effectively. Compare power dissipation against other family members if battery life is critical.

Analog To Digital Converters (ADC) Part Context

This part belongs to the TLC0838 family of 8-bit ADCs from Texas Instruments. It shares architectural similarities with the TLC0838C and TLC0838IPW but differs in packaging and reel configuration. The series is designed for cost-effective data conversion tasks where high precision is not the primary requirement.

Analog To Digital Converters (ADC) Replacement Considerations

The TLC0838CDW is a pin-compatible tube-packaged alternative. Verify electrical parameters remain identical before substitution. No direct drop-in replacements with different packages are confirmed in public documentation.
