ADS8332IBRGER

Analog To Digital Converters (ADC) Overview

The ADS8332IBRGER is a Texas Instruments integrated circuit featuring a 16-bit Successive Approximation Register (SAR) analog-to-digital converter with an integrated 8-channel single-ended multiplexer. It supports sampling rates up to 500 kSPS and operates on an analog supply voltage range of 2.7 V to 5.5 V, with a digital I/O supply ranging from 1.65 V to the analog supply voltage. The device utilizes a SPI-compatible serial interface with a maximum clock frequency of 40 MHz at 5 V. It is housed in a 24-pin 4 mm x 4 mm VQFN package and is rated for operation within an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel single-ended multiplexer with the SAR ADC core for flexible input configuration.
• Supports daisy-chain operation via a high-speed, wide-voltage serial interface for multi-device systems.
• Includes multiple low-power modes such as deep sleep, nap, and auto-nap to minimize energy consumption.
• Features programmable end-of-conversion status signals and independent digital I/O power supplies.

Analog To Digital Converters (ADC) Applications

• Programmable Logic Controller (PLC) input modules
• Industrial process control data acquisition systems
• Medical instrumentation requiring multi-channel signal processing

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IBRGER against the manufacturer datasheet to confirm the exact packaging type, tape-and-reel quantity, and temperature grade. Ensure the ordering information matches the required RoHS compliance and moisture sensitivity level specifications for your assembly process.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight single-ended inputs are required alongside 16-bit resolution and speeds up to 500 kSPS. Compare against the ADS8331 if only four channels are needed. Verify that the system's digital logic levels align with the 1.65 V to 5.5 V I/O supply range and that the SPI timing meets the 40 MHz SCLK requirement.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS833x family, which shares a common SAR ADC kernel with the ADS8331. While the ADS8331 provides a 4-channel multiplexer, the ADS8332 expands this to eight channels. Both devices offer identical conversion performance and power characteristics, differing primarily in channel count and pinout configuration for the additional inputs.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8331IBRGER serves as a functional substitute if the application requires only four analog input channels instead of eight. Other members of the ADS833x family may be considered for pin-compatible designs, provided the channel count and specific electrical parameters meet the system requirements.
