ADS8332IPWR

Analog To Digital Converters (ADC) Overview

The ADS8332IPWR is a low-power, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an 8-channel unipolar input multiplexer and supports sampling rates up to 500 kSPS. The device operates with an analog supply voltage range of 2.7 V to 5.5 V and a digital interface supply ranging from 1.65 V to VA. Key electrical specifications include a typical integral nonlinearity (INL) of ±1.2 LSB at 2.7 V and a maximum of ±2 LSB. The input bandwidth reaches 40 MHz, while the serial interface clock frequency can extend up to 40 MHz when powered at 5 V. It is housed in a 24-pin TSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel single-pole single-throw multiplexer with on-chip sample-and-hold functionality for efficient multi-point data acquisition.
• Supports flexible power management through deep sleep, automatic non-application mode, and programmable shutdown states to minimize energy consumption.
• Features a high-speed SPI-compatible serial interface allowing independent digital I/O supplies for compatibility with various logic families.

Analog To Digital Converters (ADC) Applications

• Programmable Logic Controller (PLC) input modules
• Industrial process control systems
• Medical instrumentation
• Data acquisition systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPWR confirms the TSSOP-24 package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status and moisture sensitivity level (MSL 2) requirements for your assembly line. Ensure the ordering quantity matches the manufacturer's standard packaging specifications to avoid cut-tape premiums or availability delays.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel multiplexed input is required alongside 16-bit resolution. Compare against the ADS8331 if only four channels are needed. Verify that the unipolar input range aligns with your signal sources, as differential inputs are not supported. Check that the 40 MHz serial clock speed meets your system timing constraints.

Analog To Digital Converters (ADC) Part Context

The ADS8332 belongs to the ADS833x family of low-power SAR ADCs, designed specifically for applications requiring moderate speed and high resolution. It shares architectural similarities with the ADS8331 but distinguishes itself through its eight-channel multiplexer configuration. This series targets cost-sensitive industrial environments where power efficiency and channel count are critical design parameters.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8331 serves as a functional substitute if only four input channels are sufficient for the application. Both devices share identical core performance metrics, including resolution, sampling rate, and pinout compatibility within their respective package types.
