TLC2543IDWR

Analog To Digital Converters (ADC) Overview

The TLC2543IDWR is a 12-bit successive-approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an SPI-compatible serial interface and supports 11 single-ended analog input channels. The device operates with a maximum sampling rate of 66 kSPS and includes programmable power-down modes to minimize energy consumption. It utilizes an external reference voltage mode and accepts input signals ranging from 0 V to the analog supply limit. The component is housed in a 20-pin Wide SOIC package and is rated for an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a switched-capacitor successive-approximation architecture for high-resolution signal digitization.
• Provides flexible serial communication via an SPI-compatible port supporting both MSB-first and LSB-first data output formats.
• Includes built-in self-test capabilities to verify internal circuit functionality without external stimulus.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel sensor monitoring
• Automotive electronic control units demanding AEC-Q100 qualified components
• Data acquisition modules for environmental parameter logging

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDWR confirms the Wide SOIC-20 package and industrial temperature grade (-40°C to +85°C). Ensure the procurement source provides original manufacturer documentation or authorized distributor certificates to confirm authenticity. Cross-reference the full part number against the official Texas Instruments product page to validate current production status and lifecycle stage before finalizing orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems that require multiple single-ended analog inputs with moderate resolution. The 12-bit accuracy and 66 kSPS speed suit applications where channel count outweighs the need for ultra-high throughput. Consider the external reference requirement if system precision depends on stable voltage sources. Evaluate the serial interface compatibility with the target microcontroller's available SPI ports.

Analog To Digital Converters (ADC) Part Context

This device belongs to the TLC2543 family of 12-bit ADCs, which are widely used in embedded systems for their balance of performance and pin count. The IDWR variant specifically denotes the industrial temperature range and the wide-body SOIC packaging option, distinguishing it from standard SOIC or SSOP versions within the same functional series.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include the TLV2543 series for lower voltage operation or the TLC2543CDBR for SSOP packaging. Verify pinout compatibility and electrical specifications such as supply voltage ranges and sampling rates before substituting.
