TLC3544IDW

Analog To Digital Converters (ADC) Overview

The TLC3544IDW is a 14-bit, high-performance CMOS analog-to-digital converter (ADC) from Texas Instruments. It features four pseudodifferential analog inputs and supports a maximum throughput of 200 KSPS. The device operates on a single 5-V analog supply and a 3-V to 5-V digital supply. Key specifications include an internal 4-V reference, built-in conversion clock, and an 8x FIFO buffer. DC accuracy parameters specify integral linearity error (INL) and differential linearity error (DNL) at ±1 LSB maximum. AC performance includes a typical SINAD of 80.8 dB and THD of –95 dB at a 20 kHz input frequency.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Data acquisition modules
• Medical instrumentation
• Test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'I' suffix indicates the industrial temperature range (-40°C to 85°C). Confirm the 'DW' package designation corresponds to the 20-pin SOIC format. Ensure the specific revision level matches system requirements, as datasheet revisions may update timing or electrical characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring 14-bit precision at moderate sampling speeds. The TLC3544 is suitable when hardware default configuration is preferred, as tying SDI to DVDD eliminates software initialization. Consider the TLC3548 if eight analog channels are required instead of four.

Analog To Digital Converters (ADC) Part Context

The TLC3544 belongs to a family of low-power, high-speed ADCs that also includes the TLC3548. While the TLC3544 provides four channels, the TLC3548 offers eight channels within the same architectural framework. Both devices share identical electrical characteristics and interface protocols, differing primarily in channel count and pinout configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The TLC3544CDW serves as the commercial temperature variant (0°C to 70°C) of this component. For direct functional replacement, verify that the operating environment remains within the commercial range. No other cross-model substitutes are documented.
