ADS8344N/1K

Analog To Digital Converters (ADC) Overview

The ADS8344N/1K is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an internal multiplexer supporting up to eight single-ended or four differential input channels. The device operates with a sampling rate of 100 kSPS and utilizes an external reference voltage. Power supply requirements range from 2.7 V to 5.25 V for both analog and digital domains. It communicates via a standard SPI-compatible serial interface and is housed in a 20-SSOP package. The operational temperature range extends from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer with sample-and-hold functionality for multi-point data acquisition.
• Supports flexible input configurations including single-ended and differential modes.
• Provides high-resolution 16-bit conversion accuracy suitable for precision measurement applications.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal monitoring.
• Data acquisition and test measurement equipment.
• Battery-powered instrumentation utilizing low-voltage operation.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '1K' indicates reel packaging containing 1,000 units when sourcing. Confirm the SSOP-20 package width matches design constraints. Ensure the external reference requirement is addressed in the system design, as this component does not include an internal voltage reference source.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring moderate speed and high resolution across multiple inputs. Compare against the ADS8345 if higher channel counts are needed. Verify that the SPI interface timing aligns with the microcontroller capabilities. Consider power consumption specifications relative to thermal management requirements in enclosed environments.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS834x family of 16-bit SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS8341 and ADS8345 but offers a specific balance of channel count and package size. The N suffix denotes the commercial temperature grade and SSOP packaging variant within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8345E serves as a pin-compatible alternative offering additional channel options. The ADS8341 provides a similar architecture in a smaller 16-pin package with fewer inputs. Verify electrical parameter compatibility before substituting these devices in existing designs.
