ADS8354IRTET

Analog To Digital Converters (ADC) Overview

The ADS8354IRTET is a dual-channel, 16-bit Successive Approximation Register (SAR) Analog-to-Digital Converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 700 kSPS per channel and features an internal reference voltage source. The device supports a wide analog supply range of 4.5 V to 5.5 V and a digital supply range of 1.65 V to 5.5 V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 92 dB and a SINAD of 92.2 dB. It consumes approximately 45 mW of power and communicates via an SPI interface. The component is housed in a 16-pin WQFN package and functions reliably within an operating temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Flexible digital interface supporting standard SPI communication with multiple data formats.
• Wide supply voltage compatibility allowing operation with both 5V analog and low-voltage digital logic.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution multi-channel data acquisition.
• Medical instrumentation devices such as patient monitors and diagnostic equipment.
• Test and measurement instruments including oscilloscopes and data loggers.
• Automotive sensor interfaces for engine management and chassis control systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRTET corresponds to the WQFN-16 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly line. Ensure the ordering quantity matches the manufacturer's standard reel size to avoid cut-tape handling issues. Cross-reference the datasheet revision date to ensure alignment with current design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization and 16-bit resolution are required at speeds up to 700 kSPS. Consider the internal reference feature if board space is limited or external reference accuracy is insufficient. Evaluate the WQFN-16 thermal performance against your system's heat dissipation capabilities. Compare SNR and SINAD specifications against other SAR ADCs in the same family to ensure optimal dynamic range for your application.

Analog To Digital Converters (ADC) Part Context

The ADS8354 belongs to the ADS835x family of high-speed, low-power SAR ADCs from Texas Instruments. This series is designed for applications demanding precise analog-to-digital conversion with minimal external support circuitry. The IRTET variant specifically denotes the tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8353 offers similar functionality but operates at a lower sampling rate of 600 kSPS. The ADS7254 provides comparable performance with potential pin-out differences. Verify electrical parameters and package dimensions before substituting to ensure mechanical and functional compatibility.
