ADS8343EBG4

Analog To Digital Converters (ADC) Overview

The ADS8343EBG4 is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features four differential or eight single-ended input channels with an integrated sample-and-hold amplifier. The device operates on a single supply voltage ranging from 2.7V to 5.25V for both analog and digital domains. It supports serial communication via a standard SPI-compatible interface with a maximum sampling rate of 100 kSPS. The component is housed in a 16-lead thin-shrink small-outline package (TSSOP), designated as BG4, and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-bit SAR ADC core with a dedicated sample-and-hold stage for accurate signal capture.
• Provides flexible input configuration supporting either four differential or eight single-ended channels.
• Utilizes a standard serial peripheral interface (SPI) for straightforward microcontroller connectivity.
• Operates reliably across industrial temperatures using a single power supply architecture.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Portable medical instrumentation and diagnostic devices
• Scientific measurement and analysis equipment
• Motor control applications involving current and voltage sensing

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BG4 confirms the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against storage conditions. Check for recent product change notifications regarding manufacturing site transitions. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs needing moderate resolution with multiple input channels. Compare against the ADS8344 if eight differential inputs are required instead of four. Consider the ADS8330 series if higher sampling speeds exceeding 100 kSPS are necessary. Evaluate power consumption constraints against the specified operating voltage range.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS834x family of low-power, medium-speed ADCs from Texas Instruments. It shares architectural similarities with the ADS8341 and ADS8344 models. The family targets cost-sensitive applications where channel count and resolution balance is critical. It serves as a bridge between high-speed converters and lower-resolution multiplexed solutions.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8344E: Offers eight differential channels in a similar package class. ADS8341E: Provides two differential channels with identical electrical performance. ADS8330IBPW: Delivers higher speed but lacks the multi-channel input structure.
