TLV2543IN

Analog To Digital Converters (ADC) Overview

The TLV2543IN is a 12-bit successive approximation register (SAR) analog-to-digital converter featuring 11 single-ended analog input channels. It operates with an SPI-compatible serial interface and supports a sampling rate of 66 kSPS. The device requires external voltage references and functions within a power supply range of 3 V to 3.6 V for both analog and digital domains. Packaged in a 20-pin PDIP format, it is designed for through-hole mounting and operates reliably across a temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates 11 single-ended analog input channels with a programmable multiplexer for efficient data acquisition.
• Supports flexible serial output configuration allowing selection between most significant bit first or least significant bit first transmission.
• Includes built-in self-test mode and programmable power-down functionality to optimize system performance and energy consumption.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal monitoring
• Data acquisition modules for environmental sensing applications
• Battery-powered instrumentation utilizing low-voltage operation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure the procurement source provides valid RoHS compliance certificates. Confirm that the component matches the required 20-pin PDIP form factor for your PCB layout constraints before finalizing orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 66 kSPS throughput are sufficient for the application. It is suitable for designs operating on a single 3 V to 3.6 V supply rail. Consider alternative packages if surface-mount technology is preferred over through-hole installation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the TLC2543/TLV2543 family of 12-bit ADCs. The TLV variant specifically denotes operation at lower voltages compared to the standard TLC series. It serves as a cost-effective solution for general-purpose analog signal digitization in embedded systems.

Analog To Digital Converters (ADC) Replacement Considerations

The TLC2543IN is a functional equivalent but requires a 5 V supply voltage instead of the 3 V to 3.6 V range specified for the TLV2543IN. Verify voltage compatibility before substitution.
