ADS8327IRSAR

Analog To Digital Converters (ADC) Overview

The ADS8327IRSAR is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with an analog supply voltage range of 4.5 V to 5.5 V and a digital supply voltage range of 2.375 V to 5.5 V. The device supports sampling rates up to 500 kSPS and features a serial interface compatible with standard SPI protocols. Key performance metrics include a signal-to-noise ratio (SNR) of 93.9 dB, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1.5 LSB. It is housed in a 10-pin VSON package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Supports daisy-chaining for multi-channel system expansion
• Delivers high precision with low differential and integral nonlinearity errors
• Features a compact VSON package suitable for space-constrained designs

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise analog signal acquisition
• Medical instrumentation utilizing single-ended input channels
• Data acquisition modules for sensor interfacing

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RSAR' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the ordering part number matches the required operating temperature range and package variant to avoid compatibility issues during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 16-bit resolution is required with a maximum sampling rate of 500 kSPS. It is appropriate for applications needing a 3-wire or SPI-compatible digital interface and operation from a 5 V analog supply. Consider alternative parts if lower power consumption or a different package footprint is necessary.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS831x family of precision SAR ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS8319 but is distinguished by its specific pinout, packaging, and interface timing characteristics designed for single-channel applications.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8319IBDRCT is a documented substitute within the same product family offering identical 16-bit resolution and 500 kSPS performance. Verify pin compatibility and software interface requirements before implementing any cross-model replacement.
