TLC0838CPWRG4

Analog To Digital Converters (ADC) Overview

The TLC0838CPWRG4 is an 8-bit analog-to-digital converter (ADC) manufactured by Texas Instruments, featuring a successive approximation architecture. It operates with a single supply voltage ranging from 4.5 V to 5.5 V for both analog and digital domains. The device integrates an 8-channel multiplexer supporting differential, pseudo-differential, and single-ended input configurations. It delivers a maximum sampling rate of 31 kSPS with a typical power consumption of 3 mW. The component utilizes a serial SPI-compatible interface for data transfer and control. It is housed in a 20-pin TSSOP package and is rated for operation within the commercial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number against official Texas Instruments documentation to ensure correct suffix alignment. Confirm that the 'PWR' designation corresponds to the TSSOP-20 package and the 'G4' indicates lead-free and RoHS compliance status as specified in the manufacturer's current datasheet revision. Cross-reference ordering information directly with authorized distributors to avoid counterfeit components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and up to 31 kSPS sampling rate are sufficient for the application requirements. Ensure the system design accommodates the 4.5 V to 5.5 V supply voltage range. Consider the external reference requirement if higher accuracy than internal rail-to-rail inputs allows. Verify that the TSSOP-20 package footprint fits the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This device belongs to the TLC0838 family of 8-bit ADCs from Texas Instruments. It shares architectural similarities with other members like the TLC0838CDW but differs in packaging and specific suffix designations. The family is designed for general-purpose data acquisition tasks where moderate speed and multiple input channels are necessary without the complexity of higher-resolution converters.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-for-pin replacements include other variants within the TLC0838 series such as TLC0838CDR or TLC0838IPWR, provided the temperature grade and package type match the existing design constraints. Always verify electrical characteristics and timing parameters before substitution.
