TLV2543IDWR

Analog To Digital Converters (ADC) Overview

The TLV2543IDWR is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an internal oscillator and supports serial communication via SPI. The device provides 11 single-ended analog input channels with a maximum sampling rate of 66 kSPS. It operates on a single power supply ranging from 2.7 V to 5.5 V for both analog and digital domains. The component is housed in a 20-pin SOIC package and includes programmable power-down modes to minimize energy consumption during idle periods.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an internal oscillator to simplify system design by eliminating external clock requirements.
• Supports flexible data output formats allowing selection between MSB-first and LSB-first transmission sequences.
• Includes a built-in self-test mode to verify ADC functionality without requiring external signal sources.
• Features programmable power-down capabilities to reduce overall system power consumption.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel sensor data acquisition
• Automotive instrumentation and monitoring applications
• Portable battery-powered measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IDWR' corresponds to the SOIC-20 tape-and-reel packaging configuration. Confirm that the operating temperature range aligns with industrial specifications, typically spanning -40°C to +85°C. Ensure the external reference voltage requirements match the system design constraints before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a moderate-speed 12-bit resolution is sufficient for multi-channel applications. It is suitable for designs where minimizing external components is a priority due to the integrated oscillator. Consider the 66 kSPS throughput limit against the total channel count to ensure adequate sampling rates per channel are maintained.

Analog To Digital Converters (ADC) Part Context

This part belongs to the TLV2543 family of low-power, high-speed ADCs. It shares functional similarities with the TLC2543 but offers improved performance characteristics and lower power consumption. The IDWR designation specifically identifies the industrial temperature grade and surface-mount SOIC packaging variant within the product line.

Analog To Digital Converters (ADC) Replacement Considerations

The TLC2543IDWR serves as a pin-compatible predecessor with similar functionality but potentially different electrical specifications. Verify compatibility regarding power supply ranges and timing parameters when substituting older variants.
