TLC3574IDW

Analog To Digital Converters (ADC) Overview

The TLC3574IDW is a quad-channel serial analog-to-digital converter manufactured by Texas Instruments. It features 14-bit resolution and operates at a sampling rate of 200 kSPS. The device supports a 5-V analog supply and 3-V or 5-V digital supplies, enabling compatibility with various logic families. It accepts input voltages up to 10 V without external attenuation. Packaged in a 28-pin SOIC (DW) format, it integrates a successive approximation register architecture for efficient data conversion.

Analog To Digital Converters (ADC) Feature Summary

• Supports 10-V input voltage range without requiring external signal conditioning
• Provides serial interface compatible with standard SPI and microcontroller protocols
• Integrates four independent 14-bit ADC channels within a single package

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-voltage sensor interfacing
• Data acquisition modules for multi-channel monitoring applications
• Test and measurement equipment utilizing serial communication buses

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDW confirms the SOIC-28 package and industrial temperature range. Confirm RoHS compliance status through official manufacturer documentation. Check for end-of-life notices as legacy ADC components may have limited availability. Ensure pinout compatibility with existing PCB layouts before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four isolated 14-bit conversions are required simultaneously. Choose over higher-speed alternatives if power consumption must remain low at 200 kSPS. Verify that the 10-V input tolerance matches the sensor output levels. Consider the serial interface timing requirements against the host processor capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the TLC35xx series of serial ADCs from Texas Instruments. It serves as a quad-channel variant within the family, offering multiple conversions in one footprint. The series is designed for cost-effective data acquisition where moderate speed and high resolution are balanced.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible upgrades such as the TLC3574IDR tape-and-reel version. Evaluate newer successors like the ADS series if improved noise performance is needed. Verify that any substitute maintains the 10-V input capability and 14-bit resolution.
