TLC0834CDR

Analog To Digital Converters (ADC) Overview

The TLC0834CDR is an 8-bit successive-approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a software-configurable multiplexer with four input channels, supporting single-ended, differential, and pseudodifferential configurations. The device operates on a single 5-V supply with an input range of 0 to 5 V and utilizes a serial interface compatible with TTL and MOS logic. Characterized for operation from -40°C to 85°C, it delivers a conversion time of 32 µs at a clock frequency of 250 kHz.

Analog To Digital Converters (ADC) Feature Summary

• 8-Bit Resolution: Provides total unadjusted error within ±1 LSB.
• Multiplexer Options: Supports 4-channel inputs with configurable single-ended or differential assignments.
• Serial Interface: Compatible with standard shift registers and microprocessors via DI, DO, CS, and CLK pins.
• Wide Operating Temperature: Industrial grade (-40°C to 85°C) for the 'I' suffix variant.

Analog To Digital Converters (ADC) Applications

• Microprocessor-based data acquisition systems
• Remote sensor monitoring with serial data links
• Industrial process control instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component matches the specified industrial temperature range (-40°C to 85°C). Confirm the package type is SOIC-14 and ensure the ordering suffix corresponds to the tape-and-reel quantity of 2500 units. Cross-reference the datasheet revision SLAS094E for accurate electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model when an 8-bit resolution and 4-channel multiplexing capability are required. Ensure the system design accommodates a single 5-V supply voltage. Verify that the serial communication protocol aligns with the microprocessor's SPI or shift register interface requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the TLC0834 family, which includes variants like the TLC0834C (commercial range) and TLC0834IN (PDIP package). The 'CDR' suffix specifically denotes the SOIC surface-mount package with the industrial temperature rating and reel packaging.

Analog To Digital Converters (ADC) Replacement Considerations

Functionally equivalent to the ADC0834 and ADC0838, though these older models include an internal zener regulator network not present in the TLC0834 series. Direct pin-compatible replacements should be verified against specific application constraints.
