ADS8678IDBT

Analog To Digital Converters (ADC) Overview

The ADS8678IDBT is a monolithic, high-speed, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It integrates an on-chip track-and-hold amplifier, voltage reference, and oscillator to simplify system design. The device operates with a single +5V analog supply and a digital supply ranging from 1.65V to 5.25V. It features eight single-ended inputs and supports a sampling rate of up to 500kSPS. The component utilizes a standard SPI-compatible serial interface for data transfer and communication. It is housed in a 38-pin TSSOP package and is rated for operation over an extended industrial temperature range.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an internal voltage reference and oscillator to reduce external component count
• Supports daisy-chainable architecture for multi-device systems
• Includes programmable gain amplifier for flexible input signal conditioning
• Features over-voltage protection on all input channels

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Medical equipment such as patient monitoring and diagnostic devices
• Factory automation and sensor interface applications
• Data acquisition modules in test and measurement instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the procurement source provides valid RoHS compliance documentation. Confirm the moisture sensitivity level handling requirements prior to soldering. Validate that the supplier offers genuine components to avoid counterfeit risks associated with high-volume mixed-signal ICs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight single-ended channels are required at 14-bit resolution. Consider the ADS8678IDBT for designs needing integrated references and oscillators to minimize board space. Evaluate the 500kSPS throughput against system bandwidth requirements. Compare power consumption metrics if battery-operated constraints exist within the target application environment.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS867x family of SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS8674 and ADS8688 but differs in channel count and resolution. The ADS8674 offers four channels, while the ADS8688 provides sixteen bits of resolution. This specific model bridges the gap with eight channels and fourteen-bit precision.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8678IDBTR serves as the reel-based alternative to the tube-packaged IDBT variant. Verify package dimensions and pin assignments remain identical before substitution. Cross-reference with the ADS8674 or ADS8688 only if channel count or resolution adjustments are acceptable for the design.
