ADS8354IPWR

Analog To Digital Converters (ADC) Overview

The ADS8354IPWR 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 600 kSPS per channel and features simultaneous sampling architecture. The device utilizes a standard SPI-compatible digital interface for data output. It supports an analog supply voltage range of 4.5 V to 5.5 V and a separate digital I/O 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 power consumption of approximately 45 mW. The component is housed in a 16-pin TSSOP package and is rated for operation across an extended industrial temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling architecture ensures precise phase alignment between the two input channels without interchannel delay.
• Integrated internal reference reduces external component count and simplifies board layout compared to external reference designs.
• Flexible digital interface supports standard SPI modes with selectable clock polarity and phase for system compatibility.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-precision multi-channel data acquisition
• Medical instrumentation such as patient monitoring and diagnostic equipment
• Vibration analysis and structural health monitoring sensors

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout and electrical specifications match the design requirements. Ensure that the TSSOP-16 package dimensions align with the PCB footprint library used in the schematic capture phase. Confirm RoHS compliance status if required by regional manufacturing regulations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two differential or pseudo-differential signals is critical for maintaining phase coherence. Compare SNR and total unadjusted error specifications against application noise floors. Verify that the available SPI clock speed meets the throughput requirements of the host microcontroller or DSP system.

Analog To Digital Converters (ADC) Part Context

The ADS8354 belongs to the ADSxx54 family of high-speed, simultaneous-sampling ADCs from Texas Instruments. This series includes variants with different resolutions and sampling rates, such as the ADS8353 and ADS7254. The IPWR suffix specifically denotes the 16-pin Thin-Shrink Small-Outline Package (TSSOP) with a wettable flange option for enhanced inspection reliability.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8353 offers similar functionality but with a lower sampling rate of 500 kSPS. The ADS7254 provides 12-bit resolution at higher speeds. Verify pin compatibility and register mapping before substituting these devices in existing designs.
