TLC549CP

Analog To Digital Converters (ADC) Overview

The TLC549CP is an 8-bit analog-to-digital converter (ADC) manufactured by Texas Instruments, designed for applications requiring low-cost and easy integration with microcontrollers. It utilizes a successive approximation register (SAR) architecture with IinCMOS technology and features a serial interface compatible with SPI protocols. The device operates on a single power supply ranging from 3 V to 6 V, consuming approximately 9 mW of power. It supports a maximum sampling rate of 40 kSPS with a conversion time of up to 17 µs. The component is housed in an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Serial interface compatibility allows direct connection to standard microcontroller ports using minimal control lines.
• Low power consumption design enables operation with single-supply voltages suitable for battery-powered systems.
• Integrated system clock eliminates the need for external clock generation circuitry.

Analog To Digital Converters (ADC) Applications

• Robotics sensor data acquisition
• Temperature monitoring systems
• Voltage measurement circuits

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CP' indicates the plastic DIP package variant when sourcing replacements. Confirm RoHS compliance status as manufacturing processes evolve. Check current lifecycle status, as some variants may be discontinued or subject to limited availability constraints depending on the distributor region.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs requiring simple serial communication without complex timing requirements. Ensure the input voltage range aligns with the reference voltage settings. Consider the 8-bit resolution limits for precision applications. Verify that the host microcontroller can handle the required clock speeds for the 40 kSPS sampling rate.

Analog To Digital Converters (ADC) Part Context

The TLC549 series serves as a cost-effective solution for basic analog signal digitization. It is often compared to older models like the TLC540 and TLC545 due to functional similarities. The CP suffix specifically denotes the ceramic or plastic DIP package option, distinguishing it from surface-mount variants like the CD or IDG4.

Analog To Digital Converters (ADC) Replacement Considerations

Compatible substitutes include the TLC549CD and TLC549IDG4. These variants share identical electrical specifications but differ in packaging type. Verify pinout compatibility before swapping between through-hole and surface-mount versions.
