ADS8361IRHBT

Analog To Digital Converters (ADC) Overview

The ADS8361IRHBT is a 16-bit successive approximation register (SAR) analog-to-digital converter featuring four single-ended input channels. It operates with a sampling rate of up to 4 MSPS and utilizes a serial interface compatible with standard SPI protocols. The device requires an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply voltage between 3 V and 3.6 V. Key performance metrics include a signal-to-noise ratio of 83 dB and low power consumption characteristics suitable for battery-operated systems. It is housed in a 28-pin VQFN package designed for surface-mount applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRHBT corresponds to the intended temperature range and tape-and-reel packaging configuration. Confirm that the analog and digital supply voltages match the system requirements before integration. Ensure ESD protection measures are implemented during handling due to the sensitive CMOS input structure.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four independent single-ended inputs are required at 16-bit resolution. Consider the 4 MSPS throughput limit for bandwidth requirements. Evaluate the VQFN package thermal performance against the application's heat dissipation constraints. Verify compatibility with the host processor's serial communication timing parameters.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS836x family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with other SAR converters but is distinct in its four-channel configuration. The IRHBT designation indicates a specific commercial temperature grade and reel packaging format within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8363 is a documented alternative within the same family offering similar specifications. Verify pinout compatibility and software register settings when substituting. Check if the replacement part meets the exact voltage and interface requirements of the existing design.
