TLC5540INSR

Analog To Digital Converters (ADC) Overview

The TLC5540INSR is an 8-bit, 40-MSPS analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a semiflash architecture and operates on a single 5-V supply. The device features an internal sample-and-hold function and an analog input bandwidth of at least 75 MHz. It includes internal reference voltage generators that reduce external component requirements. The part is housed in a 24-pin SOIC package and supports an operating temperature range from -40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type, lead finish, and moisture sensitivity level. Ensure the requested variant matches the required operating temperature range and packaging quantity specifications for your production needs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed digitization is required within a single-supply system. Consider the internal reference options to minimize board space. Evaluate the analog input impedance requirements and ensure proper PCB grounding strategies are implemented to maintain signal integrity at high sampling rates.

Analog To Digital Converters (ADC) Part Context

This device belongs to the TLC5540 family of high-speed ADCs from Texas Instruments. The 'I' suffix indicates an industrial temperature rating (-40°C to 85°C), while 'NS' denotes the 24-pin Small Outline Package. Other variants include the C-series for commercial temperatures and PW packages for TSSOP configurations.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include TLC5540CNS for commercial temperature ranges or TLC5540IPW for TSSOP packaging. Verify pin compatibility and electrical specifications before substitution.
