ADS8363SRHBT

Analog To Digital Converters (ADC) Overview

The ADS8363SRHBT is a dual-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog supply voltage range of 2.7V to 5.5V and digital supply voltages of 2.3V to 3.6V or 5V. The device supports sampling rates up to 1MSPS and features simultaneous sampling capabilities for its two internal ADCs. It accommodates four differential or eight pseudo-differential input channels through an integrated multiplexer and sample-and-hold circuit. Communication is handled via a standard SPI interface. The component is housed in a 32-pin VQFN package measuring 5mm x 5mm and is rated for operation within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling architecture enables independent conversion on both channels at the maximum sampling rate without interleaving delays.
• Integrated internal reference reduces external component count and simplifies board layout compared to external reference designs.
• Flexible input configuration supports both differential and pseudo-differential modes through an onboard multiplexer.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-precision multi-channel data acquisition
• Medical instrumentation such as ECG and EEG signal conditioning
• Portable test and measurement equipment needing low power consumption

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'SRHBT' to confirm the tape and reel packaging format and temperature grade. Ensure compatibility with the required SPI mode and voltage levels before integration. Check for moisture sensitivity level handling requirements during storage and assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this model when simultaneous sampling of two channels is critical, distinguishing it from interleaved alternatives like the ADS7263 which offers lower resolution but similar speed. Consider the 16-bit resolution and 1MSPS rate against system noise requirements. Verify that the 32-VQFN package fits the available PCB footprint constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8363 family of high-speed, low-power SAR ADCs. It shares the same pinout and functional block diagram with the ADS8361 and ADS8364, differing primarily in resolution and channel count configurations within the broader series.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8363SRHBR is a compatible alternative with identical electrical specifications but may differ in packaging quantity or reel size. Verify that any substitute maintains the same VQFN-32 footprint and thermal characteristics.
