TLC0831IDR

Analog To Digital Converters (ADC) Overview

The TLC0831IDR is an 8-bit successive-approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-channel input and operates with a supply voltage range of 4.5 V to 5.5 V, typically at 5 V. The device supports clock frequencies up to 600 kHz, resulting in a conversion time of 32 μs at 250 kHz. It utilizes a serial interface compatible with TTL and MOS logic levels. The 'I' suffix indicates an industrial temperature rating from -40°C to +85°C, while the 'DR' suffix denotes an SOIC-8 surface-mount package supplied in tape-and-reel format.

Analog To Digital Converters (ADC) Feature Summary

• Serial output configured for direct microprocessor or shift register interfacing
• Software-configurable multiplexer addressing for channel selection
• TTL and MOS logic level compatibility on inputs and outputs
• Designed as a pin-compatible replacement for National Semiconductor ADC0831

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring serial data acquisition
• Microprocessor-based data logging applications
• Battery-powered instrumentation utilizing ratiometric reference modes
• Low-cost sensor signal conditioning interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status and lead finish specifications via the official packaging addendum. Ensure the component source provides valid traceability records consistent with Texas Instruments production standards.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a single-channel 8-bit resolution is sufficient for the application requirements. Consider the TLC0832 variant if dual-channel multiplexing capability is required. Evaluate the maximum clock frequency limits to ensure system timing constraints are met without exceeding the specified duty cycle ranges.

Analog To Digital Converters (ADC) Part Context

This component belongs to the TLC083x family of 8-bit ADCs, which also includes the TLC0832 (dual channel), TLC0834, and TLC0838. These devices share similar architectural characteristics but differ in channel count and complexity. The TLC0831 represents the simplest configuration within this series, offering standalone operation with minimal external components.

Analog To Digital Converters (ADC) Replacement Considerations

Texas Instruments lists the TLC0831CDR and TLC0831IP as functional equivalents within the same product line. Verify that any substitute maintains the required industrial temperature range (-40°C to +85°C) and SOIC-8 package dimensions.
