TLC2578IDW

Analog To Digital Converters (ADC) Overview

The TLC2578IDW is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an on-chip analog multiplexer supporting four single-ended or two pseudo-differential input channels. The device operates with a 5V analog supply and a 3V to 5.5V digital supply, achieving a sampling rate of 200 kSPS. It utilizes a serial interface compatible with SPI and DSP standards. The component is housed in a 20-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an analog multiplexer for multi-channel signal acquisition
• Supports flexible serial communication via SPI and DSP interfaces
• Includes built-in conversion clock and eight-word FIFO buffer
• Features programmable sample-and-hold timing control

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-point monitoring
• Data acquisition modules for sensor interfacing
• Battery-powered instrumentation utilizing low-power modes
• Automotive electronic control units for signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDW confirms the 20-pin SOIC package and industrial temperature grade. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required channel count and resolution specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 200 kSPS speed are sufficient for the application. Consider the integrated multiplexer if multiple inputs must be processed sequentially. Evaluate power consumption requirements against the available low-power modes. Verify that the serial interface timing aligns with the host processor capabilities.

Analog To Digital Converters (ADC) Part Context

This device belongs to the TLC257x family of high-performance, low-power CMOS ADCs. It shares architectural similarities with the TLC2574 but offers additional channel capacity. The family is designed for applications demanding moderate speed and resolution with versatile control capabilities. It complements other data converters in the Texas Instruments portfolio for system integration.

Analog To Digital Converters (ADC) Replacement Considerations

The TLC2574IDW serves as a functional substitute for applications requiring only two input channels instead of four. Both devices share identical pinouts, serial interfaces, and electrical characteristics. Designers should verify that the reduced channel count meets the system requirements before implementing the replacement.
