TLC0831CP

Analog To Digital Converters (ADC) Overview

The TLC0831CP is an 8-bit successive-approximation analog-to-digital converter manufactured by Texas Instruments in a plastic DIP package. It features a single-channel serial output interface designed for microprocessor or standalone operation. The device operates with a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 600 kHz, achieving a conversion time of 32 μs at 250 kHz. It is characterized for commercial temperature operation from 0°C to 70°C.

Analog To Digital Converters (ADC) Feature Summary

• Serial data link allows direct connection to standard shift registers or microprocessors without parallel bus overhead.
• Successive-approximation architecture provides efficient conversion with minimal external components.
• Inputs and outputs are compatible with both TTL and MOS logic families.

Analog To Digital Converters (ADC) Applications

• Microprocessor-based data acquisition systems
• Standalone sensor interfacing applications
• Industrial control loops requiring serial communication

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CP' corresponds to the Plastic DIP (PDIP) package and the 'C' grade indicating the 0°C to 70°C operating temperature range. Confirm RoHS compliance status via the manufacturer's current packaging addendum, as lead finish options may vary between production runs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input channel is sufficient for the application. Ensure the system requires a 5 V supply and can accommodate the serial timing constraints. For differential inputs or multiplexed channels, consider the TLC0832 variant instead.

Analog To Digital Converters (ADC) Part Context

This part belongs to the TLC083x family of 8-bit ADCs, which includes the TLC0831 (single channel), TLC0832 (dual channel), TLC0834, and TLC0838. These devices are designed to be interchangeable with National Semiconductor ADC0831 and ADC0832 equivalents.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitutes include the TLC0831CD (SOIC package) and TLC0831IP (industrial temperature grade PDIP). Verify pin compatibility and thermal specifications before substitution.

Analog To Digital Converters (ADC) FAQ

What is the maximum clock frequency supported?

The recommended operating conditions specify a maximum clock frequency of 600 kHz.

How is the reference voltage handled?

The REF input can be set equal to the maximum analog input signal value for ratiometric conversion, or connected to a fixed 5 V reference.

What happens to the output during standby?

When CS goes high, all internal registers are cleared, and the output circuits enter a high-impedance state.
