TLC0838ING4

Analog To Digital Converters (ADC) Overview

The TLC0838ING4 is an 8-bit analog-to-digital converter (ADC) from Texas Instruments, utilizing a successive approximation register (SAR) architecture. It features eight multiplexed input channels supporting differential, pseudo-differential, and single-ended configurations. The device operates on a single 4.5 V to 5.5 V supply for both analog and digital domains, consuming approximately 3 mW of power. It delivers a sampling rate of up to 31 kS/s with a serial SPI-compatible interface. Key linearity specifications include a maximum differential nonlinearity (DNL) and integral nonlinearity (INL) of +/- 0.4 LSB. The component is housed in a 20-pin PDIP package and is rated for commercial operating temperatures ranging from 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Eight-channel multiplexer allows flexible connection of multiple analog signals to a single ADC core.
• Serial interface compatible with standard SPI protocols simplifies microprocessor integration.
• Low power consumption enables operation in battery-powered or thermally constrained environments.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition.
• Data acquisition modules for monitoring sensor arrays.
• Portable instrumentation devices necessitating low-power analog front-ends.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the PDIP-20 package type matches the target PCB footprint requirements. Ensure the commercial temperature range (0°C to +70°C) aligns with the operational environment, as industrial variants may require different part numbers.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and moderate speed are sufficient for the application. Consider the external reference requirement if high accuracy is needed, as the device does not include an internal voltage reference. Evaluate the trade-off between the PDIP package size and assembly method compared to surface-mount alternatives like the IPW variant.

Analog To Digital Converters (ADC) Part Context

The TLC0838 belongs to the broader TLC0838 family of 8-bit ADCs, which includes variants with different packages such as SOIC and TSSOP, and extended temperature ranges. The 'I' designation typically denotes industrial temperature range (-40°C to +85°C), whereas the 'N' suffix specifies the commercial grade. The 'G4' suffix generally confirms green/RoHS-compliant manufacturing processes within the Texas Instruments portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

The TLC0838IPW serves as a surface-mount alternative with an extended industrial temperature range. For lower channel counts, the TLC0834 offers a 4-channel configuration. The TLV0838 provides a 3-volt supply option but differs in electrical characteristics and pinout compatibility.
