ADS8344N

Analog To Digital Converters (ADC) Overview

The ADS8344N is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an internal multiplexer supporting four differential or eight single-ended analog input channels. The device operates with a sampling rate of up to 100 kSPS and utilizes a standard SPI-compatible serial interface for data output. It requires external reference voltage and is powered by a single supply ranging from 2.7 V to 5.25 V for both analog and digital sections. The component is housed in a 20-SSOP package and supports operation across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated multiplexer allows flexible configuration of four differential or eight single-ended inputs.
• High-resolution 16-bit conversion capability ensures precise signal digitization.
• Serial peripheral interface enables straightforward connection to microcontrollers and digital signal processors.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Data acquisition and measurement instrumentation
• Portable medical equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'N' corresponds to the tube packaging variant when sourcing, as other suffixes may indicate tape-and-reel options. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring moderate speed and high resolution with multiple input channels. Ensure the system design accommodates an external voltage reference, as the ADS8344N does not include an internal one. Verify that the host microcontroller supports the required SPI clock speeds and timing constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS834x family of 16-bit SAR ADCs from Texas Instruments. It shares architectural similarities with models like the ADS8341 and ADS8345 but differs in channel count and package type. The ADS8344N specifically provides eight single-ended inputs in a 20-pin SSOP form factor.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8345E offers similar performance in a QSOP-20 package. The ADS8341E provides fewer channels in a smaller 16-SSOP package. Verify pin compatibility and electrical specifications before substituting these alternatives.
