TLC541IFNG3

Analog To Digital Converters (ADC) Overview

The TLC541IFNG3 is an 8-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with a single-ended input type and an SPI serial interface. The device integrates an on-chip 12-channel analog multiplexer, providing 11 usable input channels. It operates within an analog and digital supply voltage range of 4.75 V to 5.5 V, supporting a sampling rate of 40 kSPS. Key performance metrics include differential nonlinearity (DNL) and integral nonlinearity (INL) both specified at +/- 0.5 LSB. The component is housed in a PLCC-20 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an on-chip 12-channel analog multiplexer for multi-point signal acquisition
• Utilizes SAR architecture for efficient 8-bit resolution conversion
• Supports standard SPI serial communication for data output

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel monitoring
• Data acquisition modules for environmental sensing
• Battery-powered instrumentation with moderate speed requirements

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G3' against the manufacturer's current datasheet to confirm RoHS compliance status and lead-free manufacturing details. Ensure the PLCC-20 package footprint matches the target PCB design constraints. Confirm that the 40 kSPS sampling rate meets the system bandwidth requirements before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution with integrated multiplexing is required for cost-sensitive applications. Compare the 40 kSPS speed against higher-speed alternatives if real-time processing demands exceed this limit. Verify that the external reference voltage requirement aligns with the available power rails in the design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the TLC54x series of low-cost, high-speed ADCs from Texas Instruments. It shares architectural similarities with the TLC540 but offers increased channel count via the internal multiplexer. The IFNG3 designation indicates a specific tape-and-reel or tube packaging variant compliant with environmental standards, distinct from older non-compliant versions.

Analog To Digital Converters (ADC) Replacement Considerations

The TLC541IFN is a direct functional equivalent without the G3 suffix. For pin-compatible upgrades, consider the TLC540 series if fewer channels are acceptable. Verify electrical compatibility with any proposed substitute to ensure interface timing and voltage levels match.
